Re: Using spiffs and FreeRTOS tick hook causes crash
ESP_igrr, thanks a lot !
I tried apply IRAM_ATTR only for callback itself, but no success.

Using spiffs and FreeRTOS tick hook causes crash
Hi. In my project I'm using SPIFFS and some FreeRTOS tasks. One of this tasks (its LCD library) uses callback for ticks: https://github.com/espressif/esp-idf/blob/release/v3.1/components/esp32/include/esp_freertos_hooks.h#L90 Problem: each tasks works fine separatly. But when I'm trying use both I g...

Re: CPU cant start (spiffs and adc?)
Yes, that option increases your main application stack. 8K is lots. Just wondering if that is your problem though. When I have had an overflow error I think that that was because I have exceeded my partition size. Not sure because I just increased everything. Takes so long to build on Windows so ju...

Re: CPU cant start (spiffs and adc?)
Issue was with stack memory allocation (other library require in some define 32KB). So sheduler cant start, my two functions causes overflow, so I thought problem is with them. Decreasing library memory to 18KB solves issue. Not sure, but does changing of this in sdkconfig : CONFIG_MAIN_TASK_STACK_S...
