I am using above code. ESP-IDF version :- 5.1.2 Board :- Lilgo-t-camera s3 with PSRAM 8MB and FLASH 16MB in build

The above code is giving the below error

E (472) cam_hal: cam_dma_config(301): frame buffer malloc failed
E (478) cam_hal: cam_config(390): cam_dma_config failed
E (484) gdma: gdma_disconnect(234): no peripheral is connected to the channel
E (492) camera: Camera config failed with error 0xffffffff
E (498) example:take_picture: Camera Init Failed
me-no-dev commented 2 days ago

frame buffer malloc failed usually means that PSRAM was not enabled. Are you sure you have enabled it?

nitinGangurde commented 2 days ago

Yes, I have initialize the PSRAM in esp32-s3

cnadler86 commented 2 days ago

might be that you need to enable octal psram?
