Beaglebone freezes after login ubuntu

Hello all,

Currently I’m having some problems with my Beaglebone. The problem is that the beaglebone hangs/freezes at a certain point.
This point is not always the same, sometimes it stops before logging in, while logging in or when executing a difficult task (lsusb).
When the beaglebone freezes, the computer stops showing outputs from putty and the heartbeat (led d2) is no longer blinking.
The output of a putty session is showed at the end of this message.

My setup is as follows:
a beaglebone rev A5 connected through the usb device with the computer. I access the beaglebone from the computer (Ubuntu 11.10 kernel 3.0.0-17) with putty (ttyUSB1).
The SD-card inserted in the beaglebone is prepared with the latest ubuntu 11.10 filesystem (from http://elinux.org/BeagleBoardUbuntu , method 1 for the beaglebone)
and the kernel 3.2.0 psp6 on the boot partition.

The results are the same with the power cable attached (and the usb, but not the ethernet cable).
Also when trying method 3 from the site the results are the same.

Does anybody have a clue where to look for? Hopefully I have given enough information, if not let me know.

ps. sorry for my bad english

Hello,

Sadly no one have replied. I still hope someone encountered this problem and has a fix.
For now a quick update:

I tried to connected the beagle bone with an ethernet cable, then I logged in with ssh.
But the results are the same, after the login the beaglebone stops running.

Also I tried different kernels, but the result is still the same.

right now i’m out of idea’s, hopefully someone has an idea or something…

greetings

Hello all,

Currently I'm having some problems with my Beaglebone. The problem is that
the beaglebone hangs/freezes at a certain point.
This point is not always the same, sometimes it stops before logging in,
while logging in or when executing a difficult task (lsusb).
When the beaglebone freezes, the computer stops showing outputs from putty
and the heartbeat (led d2) is no longer blinking.
The output of a putty session is showed at the end of this message.

My setup is as follows:
a beaglebone rev A5 connected through the usb device with the computer. I
access the beaglebone from the computer (Ubuntu 11.10 kernel 3.0.0-17) with
putty (ttyUSB1).
The SD-card inserted in the beaglebone is prepared with the latest ubuntu
11.10 filesystem (from http://elinux.org/BeagleBoardUbuntu , method 1 for
the beaglebone)
and the kernel 3.2.0 psp6 on the boot partition.

The results are the same with the power cable attached (and the usb, but not
the ethernet cable).
Also when trying method 3 from the site the results are the same.

Does anybody have a clue where to look for? Hopefully I have given enough
information, if not let me know.

Couple ideas,

But first, the image used "as-is" works fine on my A2/3/5 :
http://elinux.org/BeagleBoardUbuntu#Demo_Image so you should REALLY
test that first, before building stuff on your own.. :wink:

First of all thanks for your reply. I tried a clean image of ubuntu, with the setup_sdcard.sh script.
but beaglebone still freezes. A clean setup with the Angstrom image works well.

After installing the latest GCC (4.6.3) I compiled a new kernel (with build_kernel.sh script).
but still beaglebone stops running (no heartbeat) before/during/after login ubuntu.

Yesterday I tried another distro (Archlinux) this one workes fine (untill now it doesn’t freeze).
because of available time I choose to use Archlinux. But if someone knows a solution to this problem
I will try it.

Today I had the opportunity to test a different Beaglebone. Surprisely this beaglebone works with a standard ubuntu image.

So with this I can conclude that my own beaglebone is broken. I don’t know which component is broken, but I will have to get a new one.

Thans for the help i got.

I am having a similar problem with my Rev A4 Bone using the http://elinux.org/BeagleBoardUbuntu guide as is.
Angstrom works fine for me but I want to use python and for some reason I can’t work out the python can’t load the normal sha1 libraries so I though I would simply use ubuntu.
boot looks like this:

This is one of the odd issues i was seeing to, it should be fixed in
3.2.0-psp8..

Packages are currently being built, so until they are out, here's the
script to build it..

https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.2

Regards,

I am also still seeing this issue on psp12 for the beaglebone.

Pulling the USB will allow the system to continue to boot and run normally.

Psp12 is the first (well have not tried since psp8 or so) kernel on the am33x-v3.2 branch that will run, for me, without crashing under load/disk. The shipped kernel worked fine.

Ubuntu 12.04 hf system with self hosted kernel build :-).

FYI/ plymoth steals the serial console, here is a fix (remake initrd after).
cp -v /usr/share/initramfs-tools/scripts/init-top/plymouth /etc/initramfs-tools/scripts/init-top
sed -i ‘s/^/sbin/plymouthd//sbin/plymouthd --tty=ttyO0/g’ /etc/initramfs-tools/scripts/init-top/plymouth
sed -i ‘s/^printf/#printf/g’ /etc/initramfs-tools/scripts/init-top/plymouth

TM.

Interestingly enough brining up usb0 on the host will also unfreeze the board.

Interesting,
I went through many changes of kernels as suggested by Robert Nelson and was about to try his 3.2.17-psp10.4 next when 3.2.17-psp10.1 gave hangs as I have described in earlier posts.

I had to power down the PC to do some hardware changes and magically noticed on the USB monitor that the BeagleBone had successfully booted 3.2.17-psp10.1.

Since then I've disconnected the USB port that provides the serial console.
I have upgraded from 11.10 to 12.04 (took well over 24 hours) and it's been fine even across reboots.

I haven't reconnected the USB cable for serial console access but it sure looks like it was the cause of the CPU hang timeouts.

Sid.
