Task WDT timeout
Posted: Fri Mar 10, 2023 2:07 pm
Hi,
I'm working on a project and after some time I get this at the console:
I've decoded the backtrace with the xtensa-esp32-elf-addr2line -pfiaC -e command and found this:
The point where I hand over to esp-idf is clearly at i2c_master_cmd_begin
That line looks like this:
i2c.c:1529 is this:
Any idea why this might be happening?
I'm not using I2C from different tasks, this node is using wired ethernet via lan8720 (wifi disabled), it does udp communicaiton (tcp listeners setup but no connection attempted) also simple gpio is used, pcnt is used too.
