ESP32 FreeRTOS memory allocation error

[alas21]

Hi,
I use xTaskCreate and when I use it twice it works properly but when I add one more xTaskCreate then I have error:
[E][ssl_client.cpp:36] _handle_error(): [start_ssl_client():207]: (-32512) SSL - Memory allocation failed
[E][WiFiClientSecure.cpp:133] connect(): start_ssl_client: -32512

What can be reason of that ? It used the whole available memory ?

1.   xTaskCreate(led,"led",6000,NULL,1,NULL);
2.   xTaskCreate(door,"door",6000,NULL,1,NULL);

Don't think it should have as 3 tasks of 6K bytes each alone shouldn't be enough to consume all memory. You can call

Code: Select all

heap_caps_get_free_size()

in esp_heap_caps.h to get amount of free memory of a particular type/capability. Suggest you check the amount of memory with MALLOC_CAP_INTERNAL capability after each task creation to see if you are really running out of memory.
