SPIFFS EXAMPLE

Postby pepopi » Thu Jun 08, 2023 10:44 am

Hello everyone,
I am running the spiffs example in two different ESP32. However I get watchdog error. How can I solve it? Thank you.
E (5336) task_wdt: Task watchdog got triggered. The following tasks/users did not reset the watchdog in time:
E (5336) task_wdt: - IDLE (CPU 0)
E (5336) task_wdt: Tasks currently running:
E (5336) task_wdt: CPU 0: main
E (5336) task_wdt: CPU 1: IDLE
E (5336) task_wdt: Print CPU 0 (current core) backtrace

What's the log output before

Code: Select all

E (5336) task_wdt: Task watchdog got triggered. The following tasks/users did not reset the watchdog in time:
?
It looks like the program/CPU 0 is busy doing something for about 5s before even the first write to the file. Is it formatting the SPIFFS partition?

Easiest fix may be to change the WDT configuration.
