The Apalis Linux BSP v2.7b1+ does not support the hw watchdog in u-boot out-of-the-box see a later comment in this related question. (The hw watchdog is supported from point in time where the kernel boot is triggered. Not before kernel boot.)
As adding hardware watchdog support to u-boot is very module specific I have some questions:
- Is the described generic procedure to add hw watchdog support to u-boot in the related question correct?
- If applicable: What needs to be implemented different for the Apalis TK1?
- if applicable: What needs to be implemented in addition for the Apalis TK1?
