I'd like the system's reset cause (por, watchdog etc) to be available to Linux - it's shown in the u-boot debug e.g.
"Reset cause: POR"
I've only found a few references to this in searching, and it seems that u-boot clears the register after reading?
Has anyone done any modifications to preserve this, and then been able to read it from the OS?
Thanks
Hi colinhelliwell
seems you are right, in general one can save that reset info in some
of SRC_GPR registers and use in linux.
Best regards
