I have first success after switching to GRAYSCALE format. e.g.
I (1148) camera: Detected camera at address=0x3c
I (1148) ov3660: Mismatch PID=0x0
I (1148) ov5640: Mismatch PID=0x0
I (1148) camera: Detected GC2145 camera
I (1148) camera: Camera PID=0x2145 VER=0x00 MIDL=0x00 MIDH=0x00

I (1638) cam_hal: buffer_size: 30720, half_buffer_size: 15360, node_buffer_size: 2560, node_cnt: 12, total_cnt: 10
I (1648) cam_hal: Allocating 76800 Byte frame buffer in OnBoard RAM
I (1648) cam_hal: cam config ok
I (1658) gc2145: subsample win:640x480, ratio:0.500000
W (1668) gc2145: unsupport format
Camera initialized.
Captured image. size=76800
ChatGPT suggest that I need to somehow initialize the PSRAM that has 4MB of memory. However the question is that I don’t understand how this can be done :(. If of course he says something real
