[beagleboard] Re: BBB FT232 USB Serial Settings Delay Problem

2014-03-20 Thread Bekir Bahadir
Which Kernel are you using? 
I had also several problems with kernel 3.8 and 4 Port FTDI USB->Serial 
Converter. 
With kernel 3.13 everything works fine.

[beagleboard] why different compilers available for a beaglebone black

2014-03-20 Thread siva kumar
hai all,
i found there are so many compilers available for beaglebone black based on 
which os installed 
after googled i found 
[1] generic- arm-linux-gnueabi- ,
[2] angstrom - arm-angstrom-linux-gnueabi- 
[3] linaro   - arm-linux-gnueabihf-

and some others like

[4] arm-none-linux-gnu-
[5] arm-linux-gnu-

these are the compilers available to build a kernel for beaglebone black .

my ques 

why should these many varieties available ??
any how the processors are same for all the beaglebone black.. so a generic 
compiler is more than enough to build a os for beaglebone black.
i'm have bit confusion  with these compiler's.are these are different from 
one another..if so which one is the best suit for creating os for 
beaglebone black.


thanks&
regards
siva

[beagleboard] boot messages to HDMI

2014-03-20 Thread Richard-tx
I see all manner of topics referenceing ttyO0 as the console device, but I 
don't want the boot messages to spew out the RS232 port.  I would prefer 
that the boot messages appear on the screen or be logged to a 
fileanything but have those boot messages go to the serial port.

If this is possible what do I have to change in  uENv.txt?

Re: [beagleboard] Beaglebone Black Ethernet Phy Not Detected on Boot.

2014-03-20 Thread Kees k
I have seen this problem repeatedly by A6 revision hardware, but not with 
revision A5C hardware (I am running exactly the same software on both).

Noteworthy is that the "PHY problem" only appears when powering the BBB via 
the headers. Powering via USB does not give any problems.

I tried the following:
-Use the kernel from the v3.8.13-bone40  image 
-Change some lines in davinci_mdio.c to hardcode the mask to 0 
("desperately scan all phys")

Both tries weren't lucky. It seems to me that the CPU cannot find the PHY 
chip, because it never powers up.

OK, thanks Robert, so it doesn't indicate anything amiss in my setup.

I just need to make sure that things I fire off at system start-up
don't depend on having a net connection.  It was making a number of
reverse ssh tunnels fail until I added a delay before starting them.

Change the console= setting passed to the kernel.  Exactly which line to
change depends on the install you're running.  I have the console
messages being sent to both serial and HDMI (you can pass more than one
console= setting to the kernel).

[beagleboard] Re: BBB FT232 USB Serial Settings Delay Problem

2014-03-20 Thread RT Mistler
Yes, I'm using 3.8.

Linux beaglebone 3.8.13 #1 SMP Wed Sep 4 09:09:32 CEST 2013 armv7l 
GNU/Linux.

I may give 3.13 a try.

Thanks for the info.  I may first try building the 3.8 kernel (right now 
using the prebuilt one) and adding some debug to the FT232 driver to see if 
I can determine why these problems are happening.  If I do follow that 
route and end up finding a solution, I'll post the outcome.  Of course 
another tact might be to compare the code for the driver between each 
kernel release and see if there's something obvious.

Well, if it works via USB, but not with the headers. (I didn't check
if the Ethernet can be powered from the headers.)

I'd first double check your power regulation.  It's probably dropping
from 5Volts when under load.

[beagleboard] Beaglebone Black does nothing

I am need of some serious help or some advice. I accidentally used the dd

was about to flash the eMMC with Ubuntu. Now I can't get anything out of it 
any more. When i plug it into my linux computer i get a TI 355x stuff in my 
network connections but nothing else is really seeing. I am hoping i didn't 
just nuke my BBB and have to send it back, I am sure it will cost money to 
fix and I really don't want to do that, but I did just recently purchase it.

I'm powering my BBB using P9 pins 1/2 for 0v and 5/6 for +5v, I'm
using the 'real' ethernet connection and it works fine.  It has run
with no problems for at least 24 hours, staying connected (ssh) to my

[beagleboard] Re: Beaglebone Black Ethernet Phy Not Detected on Boot.

2014-03-20 Thread Kees k




The 5V is fine (maybe a little spike of 0.8V after 60 ms PS).

However, the 3.3V gives a strange 2-stage powerup cycle. I compared a 
revision A5C to a revision A6, see plots below. 

As can be seen the A5C has a 'normal ' powerup cycle on the 3.3V, but the 
A6 a 2-stage powerup cycle. May this cause any problems with PHY?

I measure 3.3V on P9.3. 

USB powering shows the 'good' powercycle, 5V via P9.5 shows a 'bad'

Btw, I seen that in revision A6 and A4 there is an NCP349 chip between 
VDD_5V and pin 10 of the TPS65217b, which I cant see in revision A5.

[beagleboard] bare metal programming (starterware): unable to get SCLK

2014-03-20 Thread Lukas Van Iseghem
I'm develloping a bare metal application for BBB. Everything seems to work 
perfectly, but I can't seem to get any SPI_CLK signals on the pins.
I literally read the Technical Reference Manual (sections PCRM, control and 
McSPI) of the AM3358 multiple times, and I can't figure out why I don't 
measure any signal on my pins. 

I can write to the SPI registers, so the interface clock is working. 

The functional clock doesn't seem to work/be connected to the pin.

[beagleboard] BBB Failes to flash

2014-03-20 Thread Rafael Fiebig-Bindner
Hi everyone out there,
 
I wanted to flash my BBB with a new Angstrom Image, since I messed up a 
little with the old operating system, but it refuses. I insert the SD card 
with the .img file, press the isolated button (boot/or flash button or 
whatever it is called), reconnect to power, the LEDs start to glow, after 
the third glows it all stops. 3 LEDs glowing and nothing. Is there any 
explanation for this, or even any idea how to fix it? 
Btw: the old operating system still functions like I never intended to get 
rid of it.
 
Best regards
Rafael Fiebig-Bindner

I did not use the NCP349 on the BBB. What board are you looking at?

 I'm powering my BBB using P9 pins 1/2 for 0v and 5/6 for +5v, I'm
 using the 'real' ethernet connection and it works fine.  It has run
 with no problems for at least 24 hours, staying connected (ssh) to my
 desktop computer.

Press and HOLD the button until after the first user LED comes on. Sounds
like it is booting from eMMC and hanging when it detects the SD card.

Re: [beagleboard] Beaglebone Black Ethernet Phy Not Detected on Boot.

2014-03-20 Thread bkozak
After upgrading to the new kernel I setup a script to constantly soft 
reboot a revision B beaglebone black and have not seen the ethernet lockup 
once after some 800 consecutive reboots. With the old kernel I did see the 
ethernet lockup after soft reboots on the same board. 

I did however see the *libphy: PHY 4a101000.mdio:01 not found* message on 
rebooting many times. 

When you say you see the "PHY problem repeatedly" do you mean you see the 
error messages on boot or have you actually seen the ethernet fail?

http://www.elinux.org/Beagleboard:BeagleBoneBlack#Terms_of_Use describes
what you can do with the HW information we provide.

Yes there is open source SW as well, but that has some more interesting
restrictions on the usage of that code and licenses that are involved.

[beagleboard] Re: Problem with UART on the BBB

2014-03-20 Thread Richard-tx
This issue is very reminiscent of a serial port issue that occurred in the 
early days of SYSV rel 3 on Intel.  What would happen was if the baud rate 
was high enough, the interrupts would occur so frequently that the kernel 
would be preempted which would cause the OS to hang.  The fix at the time 
was to throttle the data within the device driver.  That worked well 
enough.  When processors got faster and buffered UARTs were used, 
interrupts were no longer a problem but that code remained...until the day 
when we were testing POSIX compliance on SVR4 on a SMP 486 machine. Proper 
throughput could not be achieved.  The fix was simple once the developers 
knew where to look.

I'm still looking for contributions and issue reports to

people want to review it there. Many broken links from there to be fixed 
due to a change in the root path that needs to be handled.


Also, I'm getting asked a lot about eth0. Is it supposed to be commented

Correct, it's disabled in [/etc/network/interfaces] so wicd will
configure it automatically (with any sane router/dhcp server) on
bootup (wicd seems to take a good 5-15 seconds to get a valid ip
address over dhcp, conman is slightly faster).

You can see the ethernet driver taking it's sweet time over dmesg:

[   29.139188] net eth0: initializing cpsw version 1.12 (0)
[   29.142439] net eth0: phy found : id is : 0x7c0f1

[   37.103082] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

However, if we enable it in [/etc/network/interfaces], the serial
login prompt will not show up till after eth0 gets a valid ip or the 2
minute dhcp time out.  So boot times fall from the 12-15 seconds to
30ish.

2014-03-20 Thread Todd Riffel
Varieties and choices are always nice.  It invites competition, innovation, 
improvement, etc.  Most likely all of those will build the kernel.  Picking 
the best one is up to you.  If you're interested in finding out which one 
is currently the best you could build a kernel with each and then run a set 
of benchmarks on them.

[beagleboard] Re: why different compilers available for a beaglebone black

2014-03-20 Thread lee
These are not competing products, these are all ports of GCC. GCC is a huge 
software package that takes considerable effort to build for a new 
platform, and a lot of choices to be made in how to configure it. For 
example, the "gnueabi" versions produce code compatible with a certain spec 
to allow for linking with libraries compiled the same way. The "hf" ones 
produce code that uses the hardware floating point instructions on some ARM 
processors but not others.

Personally, I think the Linaro folks have done a great job, and that 
version is quite stable, complete, and well-supported. It is also popular, 
making it more likely that your code will play well with others.

[beagleboard] Re: crontab error

2014-03-20 Thread edwin . j . slv

When the executable is not successful, the journalctl output stops with the 
following line: 

> Jan 01 00:00:07 beaglebone kernel: gpiochip_add: registered GPIOs 0 to 31 
> on device: gpio

when the executable is successful, this line follows: 

> Jan 01 00:00:07 beaglebone kernel: OMAP GPIO hardware version 0.1
>


Why would the beaglebone black stop after the gpiochip_add?


I am getting the same results using crontab and the service method below. 
 For some reason the executable file is being cleared most of the time 
after being called at boot up.  

1. Compile the required code.

2. Create a bash script that will launch the code at boot/ startup
cd /usr/bin/
Type nano 
#!/bin/bash 
/home/root/

Save and grant execute permission
chmod u+x /usr/bin/.sh
3. Create the service
nano /lib/systemd/.service
4. Edit the above file as necessary to invoke the different functionalities 
like network. Enable these only if the code needs that particular service. 
Disable unwanted ones to decrease boot time.
[Unit]
Description=
After=syslog.target network.target
[Service]
Type=simple
ExecStart=/usr/bin/.sh
[Install]
WantedBy=multi-user.target
 5.  Create a symbolic link to let the device know the location of the 
service.
cd /etc/systemd/system/
ln /lib/systemd/.service .service

6. Make systemd reload the configuration file, start the service 
immediately (helps to see if the service is functioning properly) and 
enable the unit files specified in the command line.

systemctl daemon-reload
systemctl start .service
systemctl enable .service

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?

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.

Re: [beagleboard] bare metal programming (starterware): unable to get SCLK

2014-03-20 Thread Guy Grotke
You might try using 24 or 16 Mbps instead of 48 Mbps.  The SPI clock divider 
has a 48 Mhz input, so maybe it has to actually divide by more than 1.

Subject: [beagleboard] bare metal programming (starterware): unable to get SCLK

I'm develloping a bare metal application for BBB. Everything seems to work 
perfectly, but I can't seem to get any SPI_CLK signals on the pins.
I literally read the Technical Reference Manual (sections PCRM, control and 
McSPI) of the AM3358 multiple times, and I can't figure out why I don't measure 
any signal on my pins. 

I can write to the SPI registers, so the interface clock is working. 

The functional clock doesn't seem to work/be connected to the pin.

My main code:

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?

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

[beagleboard] Accessing GPIO pins with non-root user

2014-03-20 Thread jason . fehr
I just recently got my BBB, and although the board is new to me I do have 
some experience with linux.

The first thing I did when I received the board was to flash it with the 
official Debian image. The next thing I did was create a new user with sudo 
access and logged in under that account (just a best-practices thing I 
always do).

It seems that I am unable to access the GPIO pins while using a non-root 
account. Even prepending the command with sudo doesn't work. However if I 
log in as root then everything does work as expected.

Is there a way to run these scripts from my user account or will I have to 
log in as root each time? 

Thanks in advance,

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?

[beagleboard] Is BBB I2S Capable out of the box for VOIP Applications? (SIM interface)

2014-03-20 Thread André Prado
Hello, i have a BBB and i've played with it mostly for Qt Applications
(HMI).
Now i want to use it in my home as a VOIP gateway, i saw that there is an
asterisk port ( http://www.beaglebone-asterisk.org/ ) that seems to be
pretty cool.

For this i need to interface my SIM (I2S) with the BBB, is there an I2S
GPIO and drivers for it available? I've saw some projects but they all use
the chan_dongle or something like this.

Thanks

Re: [beagleboard] BBB Failes to flash

2014-03-20 Thread Wilfredo Nieves
You can not just place the .img file on the sd card. You have to write the
file using something like win32diskimager. Which makes the image boot able.

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.

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.

[beagleboard] New Start with Beaglebone Black with Ubuntu 12.04 LTS (Urgent)

Hello everyone
I just have a new beaglebone black, But I still confusing how to get start

about it with Windows System. However I read some information about getting 
start it with Ubuntu at the website 
(http://elinux.org/Beagleboard:BeagleBoneBlack), I still do not know how to 
build it.

I just plug USB Power Cable with BBB and connect with Ethernet cable with 
it, and use the " Terminal" check the Beaglebone Black IP address like the 
picture as below:



When I write the "ssh 192.168.7.1" ut said

ianymu@ianymu-desktop:~$ ssh 192.168.7.1 -l ubuntu
ssh: connect to host 192.168.7.1 port 22: Connection refused

I do not know the reason. If someone can help I really thank you.

By the way, I would like to the project is about voice recognize and stream 
video function with Beaglebone Black, is that possible to achieve this 
function connect with Beaglebone?

The similar like the  Tony Stark's assistant JARVIS.

I am going to build the picture as below to achieve that, But I do not know 
what key point I should consider with Beaglebone Black. 




Still now, I just worry about how to getting start with Beaglebone Black on 
the Ubuntu, I hope someone can give me some advice. Thank you very much.

Ian

[beagleboard] UART1 was working, now it isnt

2014-03-20 Thread Adam Langley
I enabled UART1 and 2 in BBB (otherwise it is stock standard, no video 
attached etc).

I then connected a bluetooth module to UART1, (4 pin) and it worked - I 
then connected a second module to UART2 (4 pin) and it worked.
Now, when I go back to accessing tty on UART1, I get nothing - no response. 
I have swapped devices, and UART2 always remains accessible, UART1 never 
responds.

Any ideas why this would just stop working?
What commands do I use to check & switch the muxing for pin?

Thanks

Sorry, I m still confusing the steps on this.

Firstly, connecting ethernet cable and usb power wire with router and 
computer?!
And, open the "Terminal" on the Ubuntu 12.04
Then, put the ssh 192.168.7.2 -l ubuntu (*or other user name*)
Because I saw the website from (192.168.7.2), it said can use root for 
username, I would like to know what's the different between these two names?
Finally, the password, you just told look the wiki page, is that

did as above, the system showed "Permission denied, please try again."

[beagleboard] Encouragement for the disencouraged

2014-03-20 Thread Thorsten Gonschior
Hi to you all out there, new to the BBB, new to Linux, new to whatever?

This is no request for a particular solution but somehow a thought to whats 
wrong with me, ... or some of the others?

Never worked with Linux or Unix, never did anything else than windows and 
TI embedded stuff. I would think of me as a professional senior engineer 
for embedded systems, automotive and industrial control.

Now, I entered the embedded Linux world and I am thrilled and frustrated at 
the same time. Before some days system and software engineering was somehow 
deterministic to me, something you plan and do. yea, welcome to waynes 
world.

After reading some hundred hours in the internet, peeking through about 12 
new books I bought like hands on the beagle bone black for hyperdummies 
down to realtime driver development in subatomicmicrokernels I am almost as 
clueless as before. almost ;) 
After trying to do some really complex stuff like hello world on a php web 
page I am beginning to understand that I have to let go some very basic 
principles of thinking like an engineer if I want to act in and survive 
this new scene.

My first impression on the BBB was somehow, oh wow now I can do everything 
I always wanted for free. Today I am more on the way of thinking what I 
could do if noone or nothing unavoidably unseen screws me up, kicks me in 
the back and stabs me with a fork in my ass (in my sleep).


After this esotheric discourse for all you out there finding yourself here 
I will come to the encouragement thing I promised.
You cannot make it run? its not there? dont know where, why, how or when?

Its there and it is quite simple and so much more complex you will ever 
imagine. Know what? give a damn, go get it and make it any way you can.

Newbie/Noob Rule 1: there is no correct way, there ist never only one way, 
and what ever way you find out, if ever, its the wrong one anyway.
Newbie/Noob Rule 2: dont do it on your own. its already there. dont even 
start thinking how you can solve a subtask. just go and get your component 
out of the internet. talking caipirinha serving robots doing your laundry, 
just call for it. it will never be a 100% solution. be happy if it works 
just good enough, more or less. On the other hand, if you do it on your 
own, how perfect would you think you would do it, after endless doing your 
stuff . There is just nothing you can do on your own against the 10.000 
man years of productive work you buy with your cellphone ;) 
Newbie/Noob Rule 3: dont believe in all the creeps out there. my impression 
is that there are seemingly 50 people out there not talking crap. they are 
easy to find.
Newbie/Noob Rule 4: if you are confronted with the fishermans feed fish and 
net crap, skip the page, its not with it.
Newbie/Noob Rule 5: I dont know how, but all the people out there managed 
to make it somehow. even if you have no Idea what you are doing, in the end 
it works. you dont know why, or for how long, but it does. thanks and 
regards to all of you out there contributing to this vast community. With 
the stuff you do and how you do it, you would not have survived in any kind 
of industrial working environment. On the other hand this so professional 
industrial working environment is just loosing the edge against you. And 
that feels great :D


In direct words to the BBB and my experiences of the first days:
after two days of stumbling around to understand how to get ubuntu on my 
BBB I was able to set up my SD Card and power up the ubuntu. Just early 
enough to undertsand that Angstrom ist not half as bad as everybody tries 
to state. Now I am back to angstrom and I like it (today).
After endless discussions from guys who tried to provide the perfect way of 
setting up a so much better web server and endless attempts from me to make 
those explanations work, I found out that the BBB comes with a webserver 
and to enable stuff like php its just a two lines command. it works fine to 
me (today).
After reading horrific stories of how not to find a working FTP server 
solution for the not usable and totally crappy Angstrom distribution, I 
found out that I had to load and start an SFTP capable transfer program on 
my windows machine, connect it to my BBB and do stuff I better had done but 
reading these stories.

Some more of this happened.


My conclusions are:
1. No you dont have that problem! Its just that creep over there who 
fumbled his BBB or OS to death. Do your own stuff.
2. No its probably not perfect but its great and it works (most of it)
3. Angstrom server is currently down. I am missing documents on the 
distribution and some manuals or tutorials that are NOT written from the 
wise guys out there.
4. I am looking forward to work with this great device, the good community 
and these damn ideas I still have with the BBB

My only real issue that I have no idea what the Angstrom is realling 
capable of and what really comes with it. Yes I know I can read the 
manifest, but it doe

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?

 In other words, I have been waiting for a month an a half to be able to buy
 a audio cape (in France) an so far every "where to buy" is out of stock.
 
 But anyway I wanted to make a custom audio cape based on the available one.
 
 I looked at the schematics (Rev A) and saw there was a lot of DVI things in
 it. Then I saw a yet-to-come Rev B with what seems to be a much cleaner PCB
 (audio only ?). Plus it has a AIC3104 (instead of the 3106) which adds
 selectable bias voltage !
 
 So : nowhere to buy + available schematics (I hope) = let's build it !
 
 Does anyone have any info that could help me getting started ?

[beagleboard] switching distribution

2014-03-20 Thread janszymanski12345
Hi,

 I need to get back to BBB to do a project involving openCV.
I see here http://www.elinux.org/Beagleboard:BeagleBoneBlack the following 
statement:
"We will be moving to Debian in the next few weeks"

What distribution should I use if my basic concern is the application 
execution speed?
In the past I've used Angstrom and have some (little) experience with 
Ubuntu on desktop and know nothing about Debian.

After this esotheric discourse for all you out there finding yourself 
here I will come to the encouragement thing I promised.

You cannot make it run? its not there? dont know where, why, how or when?

Its there and it is quite simple and so much more complex you will 
ever imagine. Know what? give a damn, go get it and make it any way 
you can.


Newbie/Noob Rule 1: there is no correct way, there ist never only one 
way, and what ever way you find out, if ever, its the wrong one anyway.
Newbie/Noob Rule 2: dont do it on your own. its already there. dont 
even start thinking how you can solve a subtask. just go and get your 
component out of the internet. talking caipirinha serving robots doing 
your laundry, just call for it. it will never be a 100% solution. be 
happy if it works just good enough, more or less. On the other hand, 
if you do it on your own, how perfect would you think you would do it, 
after endless doing your stuff . There is just nothing you can do 
on your own against the 10.000 man years of productive work you buy 
with your cellphone ;)
Newbie/Noob Rule 3: dont believe in all the creeps out there. my 
impression is that there are seemingly 50 people out there not talking 
crap. they are easy to find.
Newbie/Noob Rule 4: if you are confronted with the fishermans feed 
fish and net crap, skip the page, its not with it.
Newbie/Noob Rule 5: I dont know how, but all the people out there 
managed to make it somehow. even if you have no Idea what you are 
doing, in the end it works. you dont know why, or for how long, but it 
does. thanks and regards to all of you out there contributing to this 
vast community. With the stuff you do and how you do it, you would not 
have survived in any kind of industrial working environment. On the 
other hand this so professional industrial working environment is just 
loosing the edge against you. And that feels great :D



In direct words to the BBB and my experiences of the first days:
after two days of stumbling around to understand how to get ubuntu on 
my BBB I was able to set up my SD Card and power up the ubuntu. Just 
early enough to undertsand that Angstrom ist not half as bad as 
everybody tries to state. Now I am back to angstrom and I like it (today).
After endless discussions from guys who tried to provide the perfect 
way of setting up a so much better web server and endless attempts 
from me to make those explanations work, I found out that the BBB 
comes with a webserver and to enable stuff like php its just a two 
lines command. it works fine to me (today).
After reading horrific stories of how not to find a working FTP server 
solution for the not usable and totally crappy Angstrom distribution, 
I found out that I had to load and start an SFTP capable transfer 
program on my windows machine, connect it to my BBB and do stuff I 
better had done but reading these stories.


Some more of this happened.


My conclusions are:
1. No you dont have that problem! Its just that creep over there who 
fumbled his BBB or OS to death. Do your own stuff.

2. No its probably not perfect but its great and it works (most of it)
3. Angstrom server is currently down. I am missing documents on the 
distribution and some manuals or tutorials that are NOT written from 
the wise guys out there.
4. I am looking forward to work with this great device, the good 
community and these damn ideas I still have with the BBB


My only real issue that I have no idea what the Angstrom is realling 
capable of and what really com

Had a similar experience 28 yrs embedded many RTOS some linux/UNIX like DEVICE 
DRIVERS preference
I struggled just getting a kernel to build even after being trained by TI

LInux -> to me access to lots of app code if thats what you need  

 the cost a ton of overhead and too many places to look when it doesn't work 

 loss of bare metal control and embracing the printf debug model
Been able to finally build uboot and kernel from scratch then I realized the 
revolution was never coming
beyond handheld pc like devices Linux will never COMPLETELY replace bare metal 
or an RTOS
SO i have the boards have seen only one emebedded med device using am35x and 
linux/wifi drivers 

Meanwhile
I'm back to using SMP  VxWorks with 8 core POwerPC Serial Rapid IO, fibre 
channel, And guesss what
yes printfs. only the BSP team gets a JTAG

ARM has not replaced all other processors and RTOS or barebone on a multitude 
of DSP's and uC AND sOC is where all the jobs are I get called for are 

It all sounded so good and what a noble cause Linux on a TI chip in every 
American school and company (-:

[beagleboard] Re: UART1 was working, now it isnt

2014-03-20 Thread Adam Langley
Some progress... I don't know why it changed from working, to not working, 
but this is a comparison of my UARTS

1: uart:OMAP UART1 mmio:0x48022000 irq:89 tx:5 rx:0 RTS|CTS|DTR|DSR|CD|RI
2: uart:OMAP UART2 mmio:0x48024000 irq:90 tx:13 rx:38 RTS|CTS|DTR|DSR

UART2 works, and 1 doesnt.

How (on the command line) can I disable CD/RI for UART 1 so that its the 
same configuration as UART2?

Yes, Ubuntu is based on Debian. One major difference is that Ubuntu uses
Upstart for its System-V init daemon. Where as Debian starting with Jessie
is / was supposed to use Systemd.

Does anyone know of a JTAG adapter for the BBB that will connect to the 
IAR/Segger iJet?

The Samtec FTR-110-03-G-D-06 does not have the correct spacing or pin-out.
The two rows have the correct pin-to-pin spacing but the two rows are too 
far apart (.05inX.05in pitch)
The IAR interface has the following pinout:
1 VTref   2 SWDIO/TMS
3 GND   4 SWCLK/TCK
5 GND   6 SWO/TDO
7 N/C 8 TDI
9 GNC  10 nRESET
11 TgtPwr 12 N/C
13 TgtPwr 14 N/C
15 GND 16 N/C
17 GND 18 N/C
19 GND 20 N/C

Thanks in advance for any help!!!

 Looks like more things to learn and more problems to solve and I though I

I need GUI for webcam and from what I see so far I need to install it 
myself for Ubuntu - so far it boots but no GUI
With a Debian image taken from the link provided I have the error:
"Openbox Syntax Error.
One or more XML..
Start tag expected '<' Not found"
Nothing happens after that.
What is the fix?

I've only seen this happen with one microSD card. (one that i've been
flashing daily for 6 months or so) It seems to happen when either your
usb-microsd adapter is failing or a bad microSD.  First try recreating
the microSD.

I have a number of products with am335x processors running at different

course the linux kernel is the same for both products but the system does
not know correctly which frequency should be used. 1GHz version runs fine
at 1GHz, but the 300MHz version is not limited to 300MHz. Here is what
cpufreq-info prints at am3352bzczd30:

root@arm:~# cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpuf...@vger.kernel.org, please.
analyzing CPU 0:
  driver: omap
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 300 us.
  hardware limits: 275 MHz - 720 MHz
  available frequency steps: 275 MHz, 500 MHz, 600 MHz, 720 MHz
  available cpufreq governors: conservative, userspace, powersave,
ondemand, performance
  current policy: frequency should be within 275 MHz and 720 MHz.
  The governor "ondemand" may decide which speed to use
  within this range.
  current CPU frequency is 275 MHz (asserted by call to hardware).
  cpufreq stats: 275 MHz:nan%, 500 MHz:nan%, 600 MHz:nan%, 720 MHz:nan%

As you can see it is capable to run at 720MHz which I don't consider to be
safe for this specific model of processor. Is there any way to read the
marked frequency from CPU registers and limit the PLL?
