Broken SDCard and watchdog triggering

[Aeronautic]

I got one sd card that seems to be broken: cant write anything using computer.
Using esp32, card is correctly detected, I am able to read every sector but when writing with sdmmc_write_sectors to some sectors eg. 0x23d, 0x23e, 0x2bd, 0x2be watchdog is triggered:

Code: Select all

[0;31mE (22102) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:[0m
[0;31mE (22102) task_wdt:  - IDLE1 (CPU 1)[0m
[0;31mE (22102) task_wdt: Tasks currently running:[0m
[0;31mE (22102) task_wdt: CPU 0: IDLE0[0m

[0;31mE (22102) task_wdt: Aborting.[0m
abort() was called at PC 0x400d1b3b on core 0

That may be because the SD card is at its end of life, when it happens you can read but not write to the card, that is part of why they are called secure disk card, because you don't lose the data. Perhaps the IDF don't handle correctly that state, and stays wanting for a response from the SD card until the watchdog gets triggered.

Exactly it was the thing that happened, nevertheless I create application that saves lots of data shouldn't trigger watchdog and block everything for broken sector. I am looking for a way to protect such exception
