Hello, I was just confronted with this as well. The cause is that the program is trying to allocate memory in PSRAM, but by default the PSRAM component is not included. You have to add esp_psram yourself like this:

./main/CMakeLists.txt

idf_component_register(SRCS take_picture.c
                        PRIV_INCLUDE_DIRS .
                        PRIV_REQUIRES nvs_flash esp_psram)

A minimal test to see if PSRAM is working:

#include <esp_psram.h>

size_t psram_size = esp_psram_get_size();
printf("PSRAM size: %d bytes\n", psram_size);

Also make sure to set your PSRAM to the correct mode (Octal or Quad, depending on your board) in idf.py menuconfig or the VSCode extension, or whatever you use to configure that. Espressif's development environment is a bit confusing..

The problem was solved by adding this parameter .fb_location = CAMERA_FB_IN_DRAM,

I have just the same error!
tried with arduino framework and the code works great!
it seems that the idf is missing something in the camera initialization

Another thing which seems to cause me grief is this line in the camera config in take_picture.c:

    //XCLK 20MHz or 10MHz for OV2640 double FPS (Experimental)
    .xclk_freq_hz = 20000000,

My camera apparently didn't like the 20 MHz mode and only worked sporadically. When I changed it to 10000000 Hz, it started working fine.

That solved your issue precisely because PSRAM (slow but big external RAM) was not enabled. DRAM (small but fast internal ram) however is quite small so you can only take quite small pictures, SVGA and below I believe. If you need bigger resolutions try the fix above.

thank you Although I don’t understand much, I’m very grateful. The problem has been solved.

DRAM (small but fast internal ram) however is quite small so you can only take quite small pictures, SVGA and below I believe. If you need bigger resolutions try the fix above.这恰恰解决了您的问题，因为 PSRAM（缓慢但大的外部 RAM）未启用。然而，DRAM（小但快速的内部内存）非常小，因此您只能拍摄很小的照片，我相信是 SVGA 及以下。如果您需要更大的分辨率，请尝试上面的修复。

Can you write a simple example? I didn't understand how you solved it. I think you're right. I combined the ap example with the camera example and got an error again. I think it's the problem you mentioned.
