Dear Stefan Roese,
In message 201005201355.01964.sr@denx.de you wrote:
Also I would like to determine in u-boot if a reset was caused by the watchdog timer using the TSR WRS field. If it was reset by the watchdog we will boot into a failsafe partition to protect against system update errors.
Has anyone done something like this?
Such a detection is not implemented for PPC4xx. Not sure if it's implemented for any other architecture.
I think lwmon5 performs such checking; eventually this is buryied somewhere in the POST code.
Best regards,
Wolfgang Denk
