ESP32 restarting while running a task

While I’m running this specific task, sometimes it works fine but sometimes it reboots continuously.

Guru Meditation Error: Core  0 panic'ed (Interrupt wdt timeout on CPU0).

Seems like this malloc if failing: esp-afr-sdk/esp_adapter.c at 9e3992ead78da4e9c4c0c6082d719640f258d29c · espressif/esp-afr-sdk · GitHub

Would you please try to enable CONFIG_SPIRAM_TRY_ALLOCATE_WIFI_LWIP in your sdkconfig?

Thanks.

I already have it enabled in my sdkconfig file.

CONFIG_SPIRAM_MALLOC_ALWAYSINTERNAL=16384
CONFIG_SPIRAM_TRY_ALLOCATE_WIFI_LWIP=y
CONFIG_SPIRAM_MALLOC_RESERVE_INTERNAL=32768
CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY=y
CONFIG_SPIRAM_CACHE_WORKAROUND=y

Again got this similar error but at a different location.

None of the code in this call-stack is from us. I would recommend asking on Espressif forum.

Thanks.

Oh okay, will do that. Thanks for the support.

Did you get to solve it? Please I’m having a similar issue.
