How can I increase wifi task stack size?

Postby jsam589 » Mon May 11, 2020 7:50 pm

Task "wifi" is overflowing its stack sometimes and when I just checked the high water mark, it was 48 bytes (i.e. very close to stack overflow!). I am using v4.0 stable IDF. I don't see a CONFIG parameter to increase the stack for wifi. Although many other system tasks have adjustable sizes. Am I missing something?

I already have these increased parameters in sdkconfig.defaults:

Code: Select all

CONFIG_ESP_SYSTEM_EVENT_TASK_STACK_SIZE=6144
CONFIG_ESP_MAIN_TASK_STACK_SIZE=6144
CONFIG_ESP_TIMER_TASK_STACK_SIZE=3584
CONFIG_ESP_IPC_TASK_STACK_SIZE=2048
Console output

Code: Select all
