Why this installation fails? Should I create a directory before launch it?

You can find them listed in the datasheet of the processor. Use the signal
name on the expansion header schematics to start..

[beagleboard] Why is eclipse prompting me for password when trying to connnect to BBB through remote systems?

[vinaydivakar1990]

Hi Everyone,

I have recently started getting my hands on with the BBB and have been 
following Derek Molleys blog. Presently I am following his video on cross 
compiling using eclipse luna in chapter 7 
http://exploringbeaglebone.com/chapter7/. However I am facing a bit of a 
problem here trying to have access to my BBB using the remote systems on 
eclipse. The problem is as follows:

When I try to connect to the BBB, a window pops up stating that I am using 
the default username and password as shown in the image, as I had not set 
any password for my BBB. Then, once I click "OK", then another window pops 
up as shown in the image, prompting for requirement of password in order to 
access the files on my BBB.

Now, I do not know what password is it asking for? and why is it prompting 
for a password, as I haven't set any?. Can anyone provide me some support 
on resolving this issue and shed some light If I am doing anything wrong?. 

Thank you all in advance!


Regards
~VD

[beagleboard] Re: Cannot install minicom with Jessie 8.3 lxqt

[guy . smith]

Hello Robert,

Thanks for your reply.

I did the apt-get update and then apt-get install minicom and that worked 
fine, thanks.

I then tried to follow the instructions at 
https://github.com/beagleboard/bb.org-overlays/blob/master/readme.md

I type the following:

git clone https://github.com/beagleboard/bb.org-overlays
cd ./bb.org-overlays
dtc --version  (response:  Version: DTC 1.4.1-g1e75ebc9)
./dtc-overlay.sh
./install.sh
zcat /proc/config.gz | grep CONFIG_BONE_CAPEMGR  (repsonse:  
CONFIG_BONE_CAPEMGR=y)
cd /opt/scripts/tools
git pull

The next five steps just say:

v4.1.x-ti:
v4.1.x-ti + Real Time:
v4.1.x mainline:
v4.1.x mainline + Real Time:
v4.3.x mainline:

and then a command for each one.  I think this is to run a script which 
updates the kernel.  If I type uname -r I get 4.1.15-ti-rt-r43 so I'm 
guessing I should run the script for "v4.1.x-ti + Real Time" (rt meaning 
Real Time??).

Part of the response is:

info: you are running: [4.1.15-ti-rt-r43], latest is: [4.1.15-ti-rt-r40] 
updating...

then the update proceeds and seems to completre OK.

The next two steps just say:

capemgr: enable/disable capes on kernel cmdline:
capemgr: enable/disable capes with slots:

I'm guessing that this is showing two different methods to enable/disable 
capes on the BBB.  Since the lernel command line seems to need cape part 
numbers and I've no idea what these might be, I've tried the slots 
commands.  I type:

cat /sys/devices/platform/bone_capemgr/slots

and I get:

 0: PF  -1
 1: PF  -1
 2: PF  -1
 3: PF  -1
 4: P-O-L-   0 Override Board Name,00A0,Override Manuf,cape-universaln

 The instructions only show entries 0 to 3.  I type:
 
 sh -c "echo 'BB-UART1' > /sys/devices/platform/bone_capemgr/slots"
 
 and I get:
 
 sh: echo: I/O error

 Can you tell me what I am doing wrong?
 
 Thanks.

[beagleboard] Re: Cannot install minicom with Jessie 8.3 lxqt

[Soapy Smith]

I think there is a conflict you can see in the dts files for 
"exclusive-use", P9.26.
Not sure, but I think this will cause the IO error message.
The dts files are in /opt/source/bb.org-overlays/src/arm.

cape-universaln:
"P9.26",

BB-UART1:
exclusive-use =
"P9.24", // uart1_txd
"P9.26", // uart1_rxd

Just to preclude the obvious, you are running this either as root or via sudo, 
right?

[beagleboard] PyBBIO development

[Alexander Hiam]

Hi all - I just wanted to put it out there that I've been pretty short on 
time to work on PyBBIO (https://github.com/graycatlabs/PyBBIO), so if 
there's any BeagleBone + Python developers / enthusiasts out there 
interested I'd appreciate the help! Pull requests are always welcome, but I 
would love to work towards getting one or more people added as 
collaborators on the repo.

[beagleboard] Re: Why is eclipse prompting me for password when trying to connnect to BBB through remote systems?

[Graham]

Assuming an unmodified Debian release.

If you log in as 'debian', you need a password, which is given to you as 
part of the log-in dialog.

If you log in as 'root', you do not need a password.

Re: [beagleboard] Failure to recognize SD card inserted at runtime

[Hilmar Lapp]

Any chance someone has an idea what might be going wrong here? I’d be happy to 
reformat the card or take other destructive measures, but right now the device 
for the card is not even showing up under /dev when the card is inserted.

Is it that the 4.1.15-ti-r40 kernel doesn’t support hot-plugging of uSD cards? 
If so, anything I can do to change that? And I’m not sure how to boot into the 
eMMC when the card is inserted in at boot. (The system will boot into the SD 
card if inserted.)

Any updates on this? 
I have a simple web-browser application, which I'd like to run in 60Hz 
rather than the 24. We have no use for audio.

[Gerald Coley]

You cannot do 60Hz. The processor will not support 60Hz.

Doesn't seem un-normal...

what kernel?

uname -r

what rootfs?

lsb_release -a

For ethX, how do you have the rootfs setup to enable it?
(/etc/network/interfaces network-manager, etc..?)

[beagleboard] Cape manager on linux 4.1: can't load bone_eqep2b cape

Re: [beagleboard] What limits Beagle Board Black HDMI resolution

[John Syne]

Plug your numbers into this video timing calculator and you will see that given 
the AM3358 max pixel clock rate of 126MHz, you cannot do 60Hz.

Good point, we can't do that:

https://github.com/beagleboard/bb.org-overlays/commit/cc5c45529402f5e8cea86b703c6e148cf10c0ffc

use "bone_eqep2b" for the one that doesn't conflict with hdmi..

[beagleboard] Questions about boot configuration

[Zachary Jacobs]

Hello,

I'm currently configuring a BeagleBoneBlack (Element14) to be used in a 
remote location to store a very large amount of sensor data at any given 
time.  To do this, I wanted to boot directly from the SD card so I changed 
the boot flag on the eMMC.  However, after using this setup for a few 
months, my SD card became corrupted.  Whenever I try to boot using that 
card, it boots into recovery mode and suggest that I run fsck.  I tried to 
do this with no success: 
 https://gist.github.com/zachjacobs/7f7d1d6f9bf3c8e424f9.  I am using an SD 
card that has built in wear leveling so I don't think the issue was caused 
by too many read/write cycles.

My application may require intermittent power cycling so I need to limit 
the chance of file system corruption and need to ensure a reliable boot up 
procedure if that does happen.  My initial thought is to have an image on 
the eMMC and a duplicate image on the first partition of the SD card.  If 
the eMMC boot fails then boot from the SD card.  In that scenario, both 
boot methods would use a secondary partition on the SD card to store the 
data.  I have tried to set this up by using the latest Jessie snapshot 
flasher image for the eMMC and the microSD/standalone image for my SD card. 
 When I boot with the SD card plugged in (without pushing the S2 button), 
it skips the eMMC and boots straight to the SD card.  When I boot without 
the SD card, it boots using the eMMC just fine.  Did I mess something up 
that caused this?  As you see in the boot sequence for the eMMC, uboot is 
looking for the SD 
card: https://gist.github.com/zachjacobs/df76521c58429bdd90d4.  And boots 
the SD card when the SD card is plugged in even though I'm not pressing the 
S2 button:  https://gist.github.com/zachjacobs/66c9e7e3e72baa1c06ab.  I 
noticed both logs show "trying to boot from mmc... bad magic".  Does this 
have something to do with it?


Questions:
Is my proposed bootup method in the first paragraph typical?
In the event of an eMMC corruption and a failed boot to emergency mode, can 
I somehow protect myself from this partial boot sequence by trying to 
automatically boot from the SD card?
Should I have concerns with eMMC corruption like I saw on the SD card?

In the second paragraph, Have I don't something to effect the boot order 
within uboot that causes the SD card to be first?

Thanks!

Zach

[beagleboard] Re: Make a backup of contents of one beaglebone black and install said contents on a second BBB

[canis]

Hi Wally

Many thanks.  I'll apologize in advance- there are terms I'm not familiar 
with; I fear I'll have to take small steps

First question, is your system running from an SD card or the eMMC?

Running the eMMC

If running from an SD card, just "clone" or duplicate the card using 
Windows or Linux tools.  If its running from the eMMC (on-board storage).  
It'll require knowing some Linux commands.   For a beginner, I'd suggest 
downloading an image as close to what is in your eMMC as you can, write it 
to an SD and then mounting the SD card using a USB to SD card adapter (this 
gets you the correct partition layout) on the BBB and using rsync or dd to 
clone (copy) the / (root) and /boot partitions from your eMMC to the SD 
card.

Is the image the list of files & folders visible upon opening BBB on my 
laptop OR the list of folders and files within Cloud 9 OR something else?

Thanks again,
canis

Re: [beagleboard] Read analog inputs BBB running Debian Jessie

[Caveman]

That has definitely gotten me one step closer, thank you.

After using that command i typed

cat /sys/devices/platform/bone_capemgr/slots
and got this result
 0: PF  -1
 1: PF  -1
 2: PF  -1
 3: PF  -1
 4: P-O-L-   0 Override Board Name,00A0,Override Manuf,cape-universaln
 5: P-O-L-   1 Override Board Name,00A0,Override Manuf,BB-ADC

Now the next step in the instructions that i've found says that I should 
search the /sys/ directory for files with "ain" in the name
find /sys/ -iname "ain*"

this results in 0 files being found.

I guess the newer kernels don't use "ain" files for reporting the inputs.  
Once again my googlefu has failed to return a useful result.

Anyone have any ideas on where exactly I find the data coming in the inputs?

Thanks in advance for any advice.

Re: [beagleboard] Read analog inputs BBB running Debian Jessie

[Caveman]

Right after I posted the last question I found the answer.

this command
cat /sys/bus/iio/devices/iio:device0/in_voltage5_raw

got me the values from the AIN5 (p9.36)

Problem solved.

[beagleboard] Re: Reading BeagleBone Serial Number

[Super Twang]

Hi all,

FWIW, based on the answers in this thread, and a little messing around with 
an element14 BBB rev C, the following command produces a result which seems 
to match the serial number printed on the bottom of the bar code sticker, 
attached to the left-most, outside edge of the P8 header.  

I don't know why it is only 9 digits long, or if it is the official serial 
number, but at least with the element14 series, it does seem to vary per 
unit.

hexdump -e '8/1 "%c"' /sys/bus/i2c/device -s 80 -n 9; echo

Re: [beagleboard] MicroSD for removable storage on BBB?

[Hilmar Lapp]

I know this is 1.5 years later, but I seem to be running into the same 
issue and am having a hard time finding anything as to how to solve this:
https://groups.google.com/d/msg/beagleboard/IeLSZ19NbMU/xeND-QH0AAAJ

Interestingly, hot plug for the uSD card works for me on a 3.8.13 kernel 
under Debian Wheezy (3.8.13-bone79 to be precise), so this must have been 
fixed in the meantime. However, it fails to work on a 4.1.15 kernel under 
Ubuntu 14.04.3 (4.1.15-ti-r40 to be precise). Would this be because it 
wasn't compiled into the kernel?

 I cannot see how removing the SD card that is the boot device can be a

 If it was just SD card storage and you issue the unmount command sure
 or if the kernel has some kind of hot swap mechanism to allow that 


 am i wrong that removing the boot device is a bad thing ?

[beagleboard] eMMC

[Cerium]

Hi!

I'm about to make a copy of the BBB, the hardware. My intentions are to 
change the outline of the board so it can fit my use (i'm working on a 
controller for my heating system). But, Im more of a HW-person so SW is not 
my strong side. What if I use a different eMMC, e.g. MTFC4GACAJCN-1M WT, a 
newer eMMC instead of the one on the BBB, MTFC4GLDEA-0M WT. Do I need to do 
some changes to the distrubition (Linux debian)?
