You can check heap like this:

Code: Select all

ESP_LOGI(TAG, "RAM left %d", esp_get_free_heap_size());
To find out if you can reduce the FreeRTOS stack size of the currently executing task to free some memory you can query the high watermark like this:

Code: Select all

ESP_LOGI(TAG, "task stack: %d", uxTaskGetStackHighWaterMark(NULL));
I never ran into code size limitations with the 4MB of flash, so I don't know how to help with that.

Don't forget your 32bit aligned free space. xPortGetFreeHeapSizeTagged(MALLOC_CAP_32BIT)

VisualGDB gives you a memory utilization report after building your project. Which lists your used DATA_FLASH, INSTR_FLASH, INSTR_RAM and DATA_RAM. No idea how they do this though.
