[176] System: Flash erase through CTRL-AP fails due to watchdog time-out

This anomaly applies to IC Rev. Engineering C, build codes QIAA-CA0, CKAA-CA0.

It was inherited from the previous IC revision Engineering B nRF52840.


Full flash erase through CTRL-AP is not successful.


WDT is enabled.


Flash is not erased. If the device has a WDT time-out less than 1 ms and is readback-protected through UICR.APPROTECT, there is a risk of permanently preventing the erasing of the flash.


Try again.
