DisplayBuffer is null!!

[AnyReader]

@tekker Hi, tekker, I have a NodeMCU-32S based on ESP32 and an OV7670 camera. I am using the newest ESP-IDF , all compiles cleanly and when I flash/run, the log shows: DisplayBuffer is null!!(in camera.c), unless i change currFbPtr=pvPortMallocCaps(3202402, MALLOC_CAP_32BIT); (in app_main.c) to currFbPtr=pvPortMallocCaps(1601202, MALLOC_CAP_32BIT);

and i add some codes to make a test:
size_t free8start=0, free32start=0, free8=0, free32=0;

free32=heap_caps_get_largest_free_block(MALLOC_CAP_32BIT);
free8=heap_caps_get_largest_free_block(MALLOC_CAP_8BIT);
free8start=heap_caps_get_minimum_free_size(MALLOC_CAP_8BIT);
free32start=heap_caps_get_minimum_free_size(MALLOC_CAP_32BIT);

ESP_LOGI(TAG, "Free (largest free blocks) 8bit-capable memory : %d, 32-bit capable memory %d\n", free8, free32);
ESP_LOGI(TAG, "Free (min free size) 8bit-capable memory : %d, 32-bit capable memory %d\n", free8start, free32start);

it print:
Free (largest free blocks) 8bit-capable memory : 144272, 32-bit capable memory 144272
Free (min free size) 8bit-capable memory : 272396, 32-bit capable memory 338868

i think it's
3202402=153600>144272 that make pvPortMallocCaps(3202402, MALLOC_CAP_32BIT) return NULL

Have you meet this issues?

@AnyReader I met the same issue .It got resolved after changing branch to framebuffer_overlay
