How do I disable the dump of the IP addresses?  If the IP has changed, it 
is wrong the majority of the time and it also appears that on occasion, the 
file is getting corrupted.

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[mbbackus]

I purchased a proto cape from sparkfun with an eeprom. Apparently I can 
write a dts file and compile it so that I have better control of the 
headers at boot time. I'm trying to control some dc motors and was only 
able to find 4 gpios and 4 more pwms that are low and stay low when the 
beaglebone boots. I can use those for now, but I imagine that in the future 
this will probably change and I'd like to know how to deal with it. I'd 
also like to be able to choose my pin layout so that it's a little more 
intuitive for my students.

So my questions are:

   1. Can I access and program the eeprom on the proto cape from the 
   beaglebone black? If so, how?
   2. How do I make the dts file?
   3. How do I compile it?
   4. Where do I put it?
   5. How do I make debian use it when it boots?

You need to update u-boot on your eMMC boot partition.

Rename "bbb-uEnv.txt" in the boot partition

mkdir disk
sudo mount /dev/mmcblk0p1 ./disk
sudo mv ./disk/bbb-uEnv.txt ./disk/uEnv.txt

I was using the March 31st image (I think) up until yesterday when I 
updated to the most recent image. One thing I liked about the march image 
is that it automatically booted to the sd card (no need to press the boot 
button). How can I implement this functionality with the newer image?

This is just the way Debian works. "stable" aka Wheezy is frozen, so
only bug fixes are allowed.  As we start getting closer to Debian
Jessie's freeze date, I'll start pushing out offical testing images.

But there's nothing stopping you from running:

sudo sed -i 's/wheezy/jessie/g' /etc/apt/sources.list
sudo apt-get update
sudo apt-get upgrade

Then you'll get systemd 204

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[David Farning]

This is a quirk of Debian.

Systemd represents a pretty fundamental shift to Linux distributions.
Conservative distributions like Debian have taken a wait and see
approach before adopting it. As a result the version of systemd in
Debian stable, Sid, is pretty old.

One option would be look at using the current development version of
Debian, Jessie, which will become the next stable release later this
year or early next year.

As with everything it is and engineering trade off; old and stable vs.
new and awesome :)

Ok, I took a little different tack. I just copied

it works great.

Yes and No... You got a null pointer dereference when you "unloaded a
cape", which is a long time old known issue. The "only" way to
properly unload a cape is to reboot with the v3.8.x based kernel.

Hi Robert,

I hope this isn't a repeat. I thought I posted a similar message earlier 
today, but it has not showed up in the group (at least for me), so I am 
retrying.

Today I downloaded and installed a fresh copy of the latest, 2014-04-14, 
Debian image. Previously I had been using your update scripts to update my 
installation to the latest version, but I noticed there wasn't an update 
script for this version when I did a git pull in the /opt/scripts directory.

While using the new version I noticed that I had the same problems with my 
mouse pointer becoming invisible whenever I log out of LXDE, and the DPMS 
screen blanking being disabled, that I had reported earlier.

To correct this I removed the ~/.xsessionrc file to get the default, On, 
state for the dpms screen blanking. I also had to add the following line to 
the end of the Device section of the /etc/X11/xorg.conf file. Without this 
line I had no mouse pointer at all.

Option "SWCursor" "true" 

I now have a mouse pointer that remains visible across LXDE logout/login 
cycles, and my screen now turns off after 10 minutes of inactivity. 

I really think this a better default setup since the BBB behave like a 
standard desktop PC (I have a USB keyboard and mouse, and an HDMI monitor). 
New users will get correct and standard operation. More experienced users 
can change these behaviors if they need to (to disable screen blanking on a 
kiosk for example), especially if there are clear instructions on how to do 
so.

While testing the changes to the ~/.xsessionrc file I notice that I am 
getting a ~/.xsession-errors file created on each reboot. This file 
contains the following message:

Openbox-Message: Unable to find a valid menu file 
"/usr/share/lxde/openbox/menu.xml"

[mbbackus]

Yes and no. The solution was worse than the problem. Updating to the 
development kernel as mentioned above resulted in better support for Wifi 
but an unstable LXDE environment. At this point I just don't rely on Wifi.

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[KurtE]

Question:  For the fun of it, I updated my system to the latest build 
(3/31) Also updated the kernel using the script you mentioned.

Then thought I would test out building and running my Hexapod code. As part 
of my code base I have some Sound output including Tones (beeps) using Alsa 
as well as Espeak... 

I git cloned the stuff down from my github project: 
https://github.com/KurtE/Raspberry_Pi  (Sorry about the project name) and 
did the stuff in my Readme file that included sudo apt-get of the stuff for 
ALSA and Espeak and got everything to build.  I use an external USB sound 
adapter.  With previous builds I was able to get the sound to work by 
creating a sound configuration file: /etc/asound.conf pcm. with the content 
of:
!default sysdefault:Device

So far when I try it with this build I am not having much luck:

Still investigating.  Suggestions?  

Seeing messages like:

kurt@beaglebone:~$ cat /etc/asound.conf

Correct, hdmi audio is currently disabled with the v3.13.x patchset,
so you'll get non-audio resolution options. I was seeing headache
inducing screen shakes on my work monitor, will try again with v3.14.x
(the patchset hasn't hit mainline yet).

I just thought others might want to know that switching to the 3.13.6-bone8 
kernel also changes the resolution of the HDMI display output from 720p 
(i.e. 1280 x 720) to 1280 x 960, a 33% increase in display real estate. I 
suspect there is no audio at this resolution, but I have a monitor 
connected and not a TV, so I can't tell.

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[mbbackus]

What is the problem with the default kernel? That wifi doesn't work good in 
general, that it doesn't connect to unsecured networks, that Wicd is buggy 
and will freeze up the BeagleBone? I went ahead and updated the kernel. I 
am now able to connect to secured and unsecured networks using the Adafruit 
dongle. I had limited success with the netgear wna1100 which definitely 
does NOW work better than the Adafruit dongle. The UWN200 also came in the 
mail today, but the BeagleBone was unable to detect it. Is it supposed to 
run out of the box on the newer images, or do I have to implement some sort 
of fix? The adafruit dongle shows up as wlan0, and the netgear shows up as 
wlan1. I read that the uwn200 is supposed to show up as ra0, but when I 
switch wicd accordingly, it still doesn't detect the dongle, and there's no 
wifi when I run ifconfig.

Also, is there any way to log into lxde using the root user? That would 
save me and my students some typing and other problems (such as opening 
certain files with leafpad, etc.).

Again, thanks for all the work you're putting into this image. You're 
ironing out a lot of the kinds that my students have been stumbling over.

The is problem with the default 3.8 kernel, if your not using any
cape's switch to the 3.13.x based kernel

cd /opt/script/tools/
git pull
sudo ./update_kernel.sh --beta-kernel

There is a default root user (no password like Angstrom) we just don't
log into that user via lxde.

My BeagleBone part of a primitive robot with a breadboard strapped to the 
top, and servo motors underneath. The wifi dongle was between both. For 
this reason, I dug out my unpowered USB hub and used it as an extender to 
get the wifi dong'e away from all the metal. I powered the beagle bone with 
an external power supply and remoted into it via usb. I was able to get the 
Adafruit dongle to connect to my secured home network 1 out of three times 
this time around as well as a secured hotspot hosted by my phone. This was 
better than the netgrear wna1100 which was only able to connect to the 
secured hotspot (not my regular home network). Neither was able to connect 
to an unsecured hotspot. Attempts to connect via wifi also seem to cause 
the BeagleBone to freeze up frequently. Any ideas?

Also, it would be really handy if the default user was root (like on 
Angstrom) so that I didn't have to type sudo su before most terminal 
commands. This would also allow me to open files more easily. I'm guessing 
this would also allow the user to reboot and shutdown the beaglebone, 
options which are missing from LXDE at this point, and which cannot be 
execute from the command line using the debian user.

+1 for NFS mounted shares. I like to share out a rootfs for my BBB, and
then run Samba from the server so I can map the drive on Windows to make
things easier for me. Since I run many dev tools on Windows, including a

Another option is to put your lighting code on a network file share, or
you can rsync the build directory to a server somewhere.  You'll
probably have to re-run some of the build steps (like the install part)
when switching to a clean OS, but it ought to take much less than 4
hours to setup from scratch, and you shouldn't have to actually
recompile anything (which is typically _slow_ on the BBB).

I worked this way when getting LinuxCNC running on the BBB.  I mounted a
home directory via nfs from a remote server, and I was able to swap
between various boards and OS installs while keeping a consistent
development environment.  This also let me use some tools running on
full-blown Linux and Windows systems that would have been a bit heavy
for the BBB (my regular text editor, some graphical git utilities, etc).

cd /opt/scripts/fixes
git pull

sudo ./debian-2014-03-04-to-2014-03-19.sh
sudo ./debian-2014-03-19-to-2014-03-27.sh

The only thing it doesn't do is update the bootloader from v2013.10 in
2014-03-04 to v2014.04-rc in 2014-03-19+

For that:

cd /opt/scripts/tools/
sudo ./update_bootloader.sh

Robert,
Thanks for the flurry of updated Debian images for testing (3/4, 3/19,
3/27).  I am happily trying the different images, but when I download the
image and "start from scratch" it takes me several hours to get back to the
point where I can use my system again.  I use Open Lighting
Architecture and
it takes me about 4+hours to do everything necessary to compile it from
source.  Could I update to your newest distros somehow by running a script
(Mar4 -> Mar19 -> Mar27)? ... or is it necessary to wipe everything out and
reflash the image from scratch?  Some of my BBBs I flash the eMMC and some
of them I boot directly from the uSD.  Thx!! (and sorry if this has already

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[mbbackus]

I downloaded and tested the March 27th image today. Thanks for including 
xrdp-it made testing wifi go much faster. Here's what I found.

   - I was able to connect to a WPA2 secured network at the school where I 
   teach
   - I was unable to connect to my cell phone when unsecured (Android 
   portable wifi hotspot)
   - I was able to connect to my cell phone if I secured the connection 
   (WPA2 PSK)
   - I was unable to connect to a WPA2 secured network at home
   - One of my students was able to connect to the WPA2 secured school 
   network, another was unable to connect
   - The students that was unable to connect to the school network was also 
   unable to connect to my cell phone (secured as well-didn't try unsecured)
   - I was able to create an ad-hoc network (at least I think it did 
   because it showed up in Wicd)
   
We were all using the tiny Adafruit dongles and tethered to BeagleBones via 
USB. Whenever we were unable to connect, we could see the connection-it 
just timed out when trying to get an IP (unsecured networks) or 
authenticating (secured network). Any ideas?

I also tried setting up an ad-hoc network. It showed up within Wicd, but I 
wasn't able to detect it with a computer, my Android cell phone, or an 
iPhone. Is ad-hoc working for anybody else?

Given the inconsistency, I'm guessing the problem is hardware (the dongle), 
so I ordered a few of the Netgear WNA1100 dongles. Should have them in a 
couple of weeks.

Also, looks like the eMMC version doesn't have Wicd functioning out of the 
box.

Thanks for all the work you're putting into this.

Okay tested, and i see the issue.. To save bandwidth i mirror the
kernel *.deb locally, which runs/updates at midnight, so the kernel
never got installed.  So i just need to add that error condition and
just rerun the script again..

Thanks for testing, sorry for the error!

Humm, that means "uenvcmd" wasn't defined in uEnv.txt.. I wonder how
that happened (1).  Does it help if you hold down the boot button?
What do you have flashed to the eMMC? (i have it setup to be
compatible with atleast Angstrom's 2013.06.20 u-boot)

That's why there are two separate downloads. To convert the flasher image
to not flash. Just remove the flash-emmc text file from the fat partition.

Robert,

I have just noticed now that my BBB is no longer blanking the HDMI output 
after a period of inactivity. 

Prior to these changes the display would blank after some period of 
inactivity, and I would have to move my mouse to get it to start sending 
video again. It has been sitting unused for an hour or more now (there is 
an ssh session open), and it has not blanked the screen.  

I googled Debian screen blanking and discovered what I think your 
.xsessionrc commands are doing.

xset s off # don't activate screensaver
xset -dpms # disable DPMS (Energy Star) features.
xset s noblank # don't blank the video device

I suspect you have disabled the DPMS features that were shutting down the 
HDMI video output. 

I don't need a screen saver, but I would like the video to blank after a 
while. So I executed an xset +dpms command and then an xset q to check the 
current settings and verify that DPMS was enabled. With DPMS enabled I 
waited for 600 seconds (10 minutes), and my display blanked as I wanted.

I see that many people are searching for a way to disable screen blanking, 
so I think this is one of those things that should be added to your FAQ for 
simple ways to accomplish basic setup changes. I think the display should 
blank by default out of the box both for the energy savings (135,000 BBB 
boards could be preventing their monitors from going to low power mode) and 
to provide a similar experience to what one gets using a Mac or PC. The FAQ 
should explain how to change it, both to blank or not blank.

Is there any other reason you are disabling DPMS?

OH Fun! ;)

I've had reports that xorg.conf change was causing lockup's when
moving icons around, hence we changed it to the .xsessonrc workaround
in the last week.

Robert,

More test results. 

I googled and found many references to adding 'Option "HWCursor" "off"' to 
the device section of xorg.conf as a fix for the disappearing mouse cursor 
issue in Debian/Ubuntu/Mint etc. These all seemed to be for PC based 
systems thought. I tried it and it did not work. I lost my mouse cursor on 
every logout.

I added the line you suggested to remove earlier 'Option "SWCursor" "true"' 
to the device section of my xorg.conf. This appears to have fixed the 
problem. I can logout and back in many times in a row, and haven't lost my 
mouse cursor since.

Robert,

I have done some more testing. I have discovered that I do have a mouse 
pointer on the login screen after the first logout after a reboot, and I 
have a mouse pointer when I log in again. If I log out again, I have no 
visible mouse pointer on the login screen, and no mouse pointer after I log 
back in. It remains the same on subsequent logout/logins until I reboot 
again. Then I can logout and back in one more time before I lose my mouse 
pointer.

Any ideas?

okay, so when i switch back to v3.8, i see this now too.. Weird, as
v3.13.x it works.  Might just have to go back to the xorg.conf
workaround.

Robert,

My .xsessionrc file looks identical to yours, and I did not have "SWCursor" 
anywhere in my xorg.conf file, so there was nothing to remove.

My mouse pointer definitely becomes invisible when I logout.

Any other ideas?

Previously we were making the mouse pointer viable by a custom xorg.conf.

However it works better if you add it via xset/xsetroot:

root@beaglebone:~# cat /home/debian/.xsessionrc
#!/bin/sh

xset -dpms
xset s off
xsetroot -cursor_name left_ptr

and just remove the  [Option  "SWCursor"  "true"] line
from /etc/X11/xorg.conf

So for me, right now the mouse cursor works between logout/logins.

Robert,

I did this update and then undid the workaround (i.e. I uncommented the 
display-setup-script line in /etc/lightdm/lightdm.conf). 

Now I no longer get the calibration screen on startup and logout of LXDE, 
however I lose my mouse pointer when I logout. The mouse pointer works on 
reboot, but if I logout of LXDE I have no visible pointer on the login 
screen or in LXDE after I log back in. The mouse does work and I can see 
where it is because some items like the LXDE menu icons highlight when I 
hover the mouse over them, but there is no onscreen pointer visible. 
Clicking the mouse buttons work as expected when I can figure out where it 
is pointing.

Is there anything else I can do to help pinpoint the problem?

Okay, quick update on this as i have the same K120 keyboard.  I'm
seeing this same issue on 3.8/3.13/3.14 so I just blacklisted this
device.

Just run:

cd /opt/scripts

to update the xinput script..

I have very seldom run into a situation where google did not give me a
correct answer. Sometimes the first hit is not always right / succinct
either. It takes experience googling to know what to look for, and this
does not always work either.

Anyway, answers linked on debian.org, and superuser are typically succinct
and correct. Also, as I had not reconfigured time zone, and dash before, or
in a while i did google searches on these myself not but a few months ago.

Regardless, this is all part of the learning process for everyone.

I did that and ended up 
at 
http://www.debian-administration.org/article/213/Changing_the_timezone_of_your_Debian_system
 
which suggested the tzselect command (which in turn suggested adding a TZ 
environment variable, which in turn led to me seeing that my .profile 
wasn't being executed, etc). 

I also saw the page at https://wiki.debian.org/TimeZoneChanges but the text 
at the top of that page and the titles of the other sections made it seem 
more about checking and adapting the system to changes in the dates of 
daylight saving etc. I just wanted to set my timezone. The section where 
"dpkg-reconfigure tzdata" is mentioned has the title "Check Configured 
Timezone", and the text of the command itself didn't lead me to conclude it 
would change my timezone. Had I read in more detail I would have seem what 
it did, but I was skimming for something that said "this is how to change 
your timezone" as on the page above.

As far as I can tell by using ps - p $$, lxterminal is already running 
bash, so adding -e bash shouldn't change anything. Adding the -l make it a 
login shell, so it sources /etc/profile and then .profile, which sources 
.bashrc if it exists. 

Without this change lxterminal runs bash as a non login shell so it sources 
/etc/bash.bashrc and then .bashrc instead. The /etc/bash.bashrc file setups 
the command prompt.

What I don't understand is why an lxterminal command with no options starts 
a bash shell, but an lxterminal -l command starts a /bin/sh shell which is 
actually a dash shell. You end up with no command prompt because it doesn't 
run /etc/bash.bashrc. There are probably other differences. This is why you 
added the -e bash option. 

Anyway this does seem like a better fix, though anything that runs /bin/sh 
will still have a different PATH without the user bin directory.

Sorry, I felt i was not clear in my last post . . .

*Also, as for how to change some default stuff, perhaps have a web page (
html file, or maybe even a node.js thing to make it more dynamic ? )*

What I mean by the above, is have an information web page on how to do
various things, like how to set time zone etc. Perhaps as part of the
getting started page thats already on the BBB.

Even though I think Debian is one of the better distro's out there because
of the fact you can simply google the answer to your questions( just one
aspect actually ) I feel that having a web page linked to from the getting
started page on how to change all teh default basic stuff would be super
helpful for new users.

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

Robert, your timezone is fine for me. I am actually AZ time myself, but
really simple to change via dpkg-reconfigure tzdata.

Also, as for how to change some default stuff, perhaps have a web page (
html file, or maybe even a node.js thing to make it more dynamic ? )

Dennis, just so you know, you should be able to google "debian" + whatever
keyword you need to know something about to find an answer. We're talking
basic Linux / Debian stuff here. For example.

google -> howto change debian timezone, and you will very likely find what
i asked about last night "dpkg-reconfigure tzdata".

Anyway, dont feel as though I am putting you down by saying  this. quite
the contrary actually. As I have been using Debian since  the 90's and have
to google many things. Especially now considering I really want to look
into using systemmd.

FYI, commenting out the display-setup-script line does not take effect 
until after you reboot.

I no longer have the calibration screen on startup or logout.

I moved that section from my .profile to .bashrc since .profile will source 
.bashrc if it exists. So a login shell will source .profile, which will 
source .bashrc and add the path. A non login shell will source .bashrc 
directly and add the path. This seems to work for me.

I'm not sure what happens for script that use #!/bin/sh since that runs 
dash instead of bash. The dash docs say it sources .profile on login shells 
so that should be OK, but for non login shells it says it looks in the ENV 
environment variable for the name of a file to execute. There is no such 
variable defined currently so it does nothing. 

Perhaps these commands should be put in a .shinit file and then set 
ENV=$HOME/.shint in the .profile file to take card of setting it for login 
shells, and have the .bashrc source this .shinit file for non login shells.

Yeap it does..

debian@beaglebone:~$ echo $PATH
/home/debian/bin:/home/debian/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games

What gets sourced first? i can patch it to check..

Ahh, I've been doing it over serial/ssh..

For lxterminal (which doesn't reference .profile according to lots of
bug reports). It works if i add:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi

into .bashrc

If there is no objections i'll probably set that up by default..

Ah ha... there is the nugget of truth I was looking for. Yes, this is the 
LXTerminal under LXDE. 

I checked and the .profile *is* executed for my serial console.

So how does one get the same path for the LXTerminal as you get using a 
serial terminal? Also, is an ssh terminal a login shell, or is like the X 
terminal?

I know that now, but yesterday when I was trying to get the timezone set 
correctly I ran the tzselect command (which seemed logical). This is the 
output of that command:

The following information has been given:

Canada
Mountain Time - Alberta, east British Columbia & west Saskatchewan

Therefore TZ='America/Edmonton' will be used.
Local time is now:Fri Mar 14 09:31:43 MDT 2014.
Universal Time is now:Fri Mar 14 15:31:43 UTC 2014.
Is the above information OK?
1) Yes
2) No
#? 1

You can make this change permanent for yourself by appending the line
TZ='America/Edmonton'; export TZ
to the file '.profile' in your home directory; then log out and log in 
again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
America/Edmonton

So I did as it suggested. I added this line to my .profile and logged out 
and in. This again seemed logical. I left it in as a simple test of whether 
or not my .profile was executed. I will remove it now.

Yes, thanks for the tip. I started by using env to dump my entire 
environment, and then just progressed to using grep to filter the dump, 
while looking into why the .profile wasn't being executed.  

Thanks again for the info.

Well, technically "armhf" is still "EABI", but over "armel" it has
hard floating point enabled by default.

It works here:

debian@beaglebone:~/bin$ nano simple.c
debian@beaglebone:~/bin$ gcc -Wall simple.c -o simple
debian@beaglebone:~/bin$ cd ..
debian@beaglebone:~$ which simple
/home/debian/bin/simple
debian@beaglebone:~$ simple
Simple Program

One thing i can do is just to add the directory by default in the image.

debian@beaglebone:~$ echo $PATH
/home/debian/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games

> It is also not adding the TZ variable to the environment.

Just use:

dpkg-reconfigure tzdata

or:

echo "Europe/Zurich" > /etc/timezone
dpkg-reconfigure -f noninteractive tzdata

The default /etc/profile sets the gaming directories up by default. So
i opted to just leave them.

/usr/local/games:/usr/games

The only thing i've done there, is to tweak the path to also include
the root "sbin" directories too for the normal user..

Hi Robert,

I'm sorry to nitpick, but this new "official" page is wrong right out of 
the gate. 

It says it is "about running an ARM EABI Debian" distribution. The Debian 
page at https://wiki.debian.org/ArmEabiPort says this is different than the 
newer armhf ABI which I believe is the basis for your images. Getting this 
kind of basic stuff correct is important.

Also, the description of how to set the timezone to your local timezone so 
that the clock displays local wall clock time is terse to point of extreme. 
It is not at all clear what the listed commands do, or why you might want 
to use them.

No need to set the variable then export it either, just do it all in one go.

export TZ="Whatever"

Also less typing to just "echo" variables

echo $HOME $PATH

Really no need for env and grep.

You are missing my point. These commands are already in the default 
.profile created for the debian user. See the pastebin.com/kjDXbEpJ for a 
copy of mine. I added the TZ environment variable at the end. 

ls ~ shows my bin directory exists
env | grep HOME shows the HOME variable as /home/debian
env | grep PATH shows the PATH as 
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

The .profile should be adding /home/debian/bin to the path, but it is not. 
It is also not adding the TZ variable to the environment.

BTW, we could probably remove the two games directories from the default 
PATH as well. I don't think many users will be using BBB for gaming.

Hi Steve,

I've started an offical page at:

http://elinux.org/Beagleboard:BeagleBoneBlack_Debian

My plan is to hint at this page in both the serial/dvi terminal along
with an ssh message on the default image.

I'll try to get the "more info" links from here
http://beagleboard.org/latest-images

also linked to that page.

Robert,
Just my $0.02 about *where* info should be stored:   I completely agree
about Dennis' "Wild West" comment.  When I first started with the BBB back
in Sep2013 all 5 of the various websites that Dennis referenced seemed to
contradict each other.  The "official" image was outdated and the most
recent images were hidden away and you almost needed a "secret knock" to
find them.  I completely understand that everything has been in a massive
state of flux, especially since all of the changes with the way Device Tree
was handled, etc, etc.  It seems to me, though, that out of the 5 websites
that Dennis referenced, perhaps 4 of them should say "Things are in a state
of massive flux right now Instead of us updating 5 websites all the
time, Please check this *one* website for the most up-to-date info."  Then
on the *1* website which is "continuously updated" it could say:  Here is
the most recent "stable" official image and here is the most recent
"development" official image.  It is strange having 5 different websites to
have to check when you are a Newbie...and then Gerald says "why didnt you
check 'the' website".

Thx!  I respect and appreciate all the work you do!!  These are challenging

No worries, I have no plans to discontinue those monthly "minimal"
images. I have a lot of users using them. Plus they support older
boards like the beagle.

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[iustinian . input]

Robert, thanks for your work. 

Is there a guide somewhere to build or a way to download a absolute minimal 
image. Something with only ssh, apt and full hardware initialization on it 
and nothing else. That would be a good base for couple of headless projects 
I am thinking about.

When I am talking about HW initialization I am only thinking about network 
and hwrng

Right now I am using this:

http://rcn-ee.net/deb/flasher/wheezy/BBB-eMMC-flasher-debian-7.4-2014-02-16-2gb.img.xz

and I will continue to use it as it is. But if you plan to stop developing 
those images I need to start thinking about another way to get a headless 
emmc debian image working.

That's interesting, the lcd/touchscreen detect script is pretty basic,
i'll have to add whitelist for some devices.

Can you pastebin this file for me:

/var/log/xinput_calibrator.pointercal.log

and the output of "xinput" you will have to run it from x11, no serial/ssh..

Yeah,

export PATH=$PATH:~/bin

in ~/.profile is all you should need..

However I am now sure that I didn't grab Robert's kernel. 😠 A pitty, for I
would have speared a lot of time.

All the Best

leafpad is installed so that would be pretty easy, to show web link
for help. xchat2 is even installed, ( i was feeling a little evil and
was temped to have that autoconnect to beagle on #freenode (it
doesn't..))

I think UTC would be best, but there should be clear instructions for

tzselect

I can pretty much dump them anywhere, but the hard question is where...


motd or the banner for ssh, together with an instruction to use rm to
get rid of the message.

Listing those basic steps there would get rid of thousands question from
people using broken, old and/or outdated instructions belonging to some
broken/old and/or outdated images.


And if some gui is supported, open an editor like gvim or similiar to 
show those instructions gui-users too (by using some autoexec mechanism

Anything else than in-image-instructions which people will see when they

I've been dumping the default username/password + the current ip
address if we get it in time to "/etc/issue" so it shows up on both
the dvi and serial terminal. We could dump an elinux link faq there
too.  Good call on the ssh message, didn't think of that.

I don't know where they should be stored, but there should definitely be 
links on the beagleboard.org main page. It seems to me that if Debian is 
going to replace Angstrom, then a link to the Debian release images and 
FAQs should be put there. Eventually, the Angstrom info could be 
deprecated, or rather archived and its visibility reduced.

It seems to me that there are currently too many places to go to get the 
various linux distributions and kernels, and none of them seem to be 
officially sanctioned as the "standard" release. This leads to unnecessary 
confusion for new users. Some info on beagleboard.org, some info at 
circuitco.com, some info at elinux.org, some info at armhf.com, etc., not 
to mention all the other stuff at ti.com.

The official wiki 
at http://www.elinux.org/Beagleboard:BeagleBoneBlack#Software_Resources 
doesn't even mention this Debian releases (and it should if you want people 
to test it). The community wiki 
at http://elinux.org/BeagleBone_Community#Debian does list a Debian 
release, but it is a different, and incompatible, arm EABI version from 
this new armhf release.

I appreciate all the hard work that people have done to prepare all this 
information, but it's a little like the wild west when you first start 
looking around.

I'd rather see a system come up "UTC" rather than some other TZ not

When, eth0 is defined in /etc/network/interfaces, the login prompt
(serial/video) can be delayed for up to 2 minutes as the system
attempts to get an ip. If a cable is NOT connected it will wait the
full 2 minutes.

So by allowing the wicd/systemd deamon to take care of it, we get the
login prompt must faster

I had rebooted many times. I hadn't paid any attention to the wicd program 
since it seemed to be for WIFI which I am not using. 

I had to open the preferences and check the option to always show wired 
interfaces (I also checked always switch to wired connection when 
available) before I saw the eth0 connection. I then clicked the connect 
button and waited until it finished. It still didn't connect, but after I 
rebooted again, it did connect using dhcp. Since then it has been 
connecting on each boot.

mean "uncomment", or did you mean "comment out".

Is it faster to boot with the eth0 defined in /etc/network/interfaces, or 
is it faster with the eth0 section commented out? Why? Is it redundant to 
define eth0 here, and then have wicd also connect eth0; or does having 
defined in the interafces file cause wicd to skip its redundant setup later?
 
On an unrelated issue, how do you setup the timezone for the time display 
on the LXDE desktop? I have set /etc/timezone. I have also used tzselect 
and added the TZ environment variable to my .profile as suggested in the 
output of tzselect. It does not appear that my .profile file is being 
executed though. I have a user bin directory in my /home/debian directory, 
and it is not being added to the path as it seems it should be by reading 
the .profile file. I checked and I don't have a .bash_profile or 
.bash_login file which would prevent .profile from executing. Any ideas?

The wicd deamon should setup eth0 within 30 seconds on 2nd boot.
(first boot there is a slight delay as the ssh key's are generated).

If you uncomment out the eth0 interface in /etc/network/interfaces
boot time falls from 15seconds to 35ish..

Nice catch, i need to remove that application from the menu. It was
requested to blank out the root password for ease of use.

Using a different 8GB SD card my BBB boots this new image as expected. 
Hopefully the bootlog from the problem card will help identify the issue.

OK, so I removed the quiet from the systemd definition and rebooted my BBB. 
It did log a lot more stuff. The complete boot log is attached. 

Since you seem t think the problem is SD card specific, I will try again 
with a different card.

Robert,

The uEnv.txt file from the FAT partition in this image (attached) does not 
have optargs defined. Both sections where optargs appears are commented out.

There is a line that says:

systemd=quiet init=/lib/systemd/systemd

I'm not sure if you mean to remove the quiet from this line, or perhaps 
something else.
