I’m testing a couple Apalis boards by rebooting them by SSH every other minute using a cronjob.
Once in a while a board gets stuck with a “CPU1 Shutdown” message displayed on the screen. The only way to wake up the board again is by manually pushing the reset button.
This is a huge problem for us, because our software uses a similar procedure out in the field.
Image Version Apalis_T30_LinuxImageV2.6_20160331
Hardware Version Apalis 1.1A
Any ideas what’s going on here?
It happened again. Here’s the output from the serial port:
