Default debian image not booting

GoogleGroups

Hi everyone,

after having my Beagleboard xM collecting dust for quite some time I decided to get back to it and give it some useful work. Unfortunally I don’t even get it to boot with the latest debian image.

My display just turns orange when I power it up and then goes black. I tried the 2 latest versions:

I tried reflashing the image (using etcher) A LOT, different sd-cards, power supplies and nothing helped.

Once I got a blinking text-cursor followed by a stuck mouse cursor on a black background, but even after waiting ~20min nothing further happened. After resetting then it again got stuck on loading the kernel and I never managed to get ahead of that anymore. Also I can’t tell any difference to the tries before. I was trying around with holding the user button at that time, but since that doesn’t really do anything for the beagleboard xM (and I couldn’t reproduce it trying pressing/holding the button) I don’t think that had anything to do with that one more successful attempt.

Now I connected it to my pc via serial and managed to get some debugging information, but unfortunally I didn’t find anything useful about those messages:

Any ideas about what is the issue here or what I could try to fix it would be nice.

Hey,

thanks at first for the quick reply. The mentioned Images look a lot more promising, but both of them won’t show anything on hdmi after the orange starting screen and will crash after some time with those messages:

`

[ 79.053771] INFO: rcu_sched detected stalls on CPUs/tasks:

`

I also tried a version from cristmas ( https://rcn-ee.net/rootfs/bb.org/testing/2017-12-24/stretch-lxqt-xm/bbxm-debian-9.3-lxqt-xm-armhf-2017-12-24-4gb.img.xz ) which froze after booting to the login, also producing no output to the hdmi.

Logs of attempts for all 3 version are attached.

Update: It seems to boot and be stable when booting without the hdmi cable attached.
