NRF9160 watchdog + OTA Update fails

[danielboe]

Hi,

I try to do a OTA Update with watchdog enabled . The OTA Update runs and boots image B but this is stopped after watchdog timeout (1Sek). In my code the watchdog runs after some boot init so after the OTA it gets not directly reinitialized. 

So what is the best practice here? I tried to disable watchdog after OTA finish but it seems not to work because if I try the disable function ( wdt_disable() ) the watchdog only tirggers.

Thanks for your help and best regards

Daniel

Hello Daniel,

In MCUboot v1.7.0, watchdog feed has been added via CONFIG_BOOT_WATCHDOG_FEED. This should solve the problem you are facing.

Hi Markus,

thanks and best regards
