Dear barebox community and hackers, we use barebox 022.04.0-dirty from https://github.com/menschel-d/meta-barebox.git in our yocto kirkstone project. This worked for ages in up to hundreds of BBBs without any issue.
Since last week I have the problem, that the system is not able to reboot (linux userspace issuing reboot command) or reset (command reset at barebox prompt) anymore in _some_ of the BBBs we got delivered from SEEED (we get a couple of hundreds a couple of times per year). Speaking of some one digit percentage. Linux userspace running, issuing reboot command: systemd-shutdown[1]: Rebooting. reboot: Restarting system -> Then gets stuck Barebox prompt, issuing reset command: Hit m for menu or ctrl-c to stop autoboot: 3 barebox@TI AM335x BeagleBone black:/ reset -> Then gets stuck This also applies to triggering the barebox's watchdog to trigger reset and also the hardware line on the BBB S2 is not working on those BBBs too! The S2 button is connected to CPU's NRESET_INOUT ball A10. If I test those use cases with stock u-boot delivered with the BBB the reset/reboot works each time. >From the symptoms I guess the barebox is not able to start in each case when it should. Where can I start to investigate such an error, what could cause the hardware glitching away that something is on the edge which does not work anymore? I learned it is something like a soft reset which is done in software, where can I look in the sourcetree for this special part?
