I use UNIT CAMERA DIY KIT.
I tested it with the latest cameraWebServer sample program.
I got the same error, so I checked the source program.
I found the following description in the comment of esp_camera.h.
typedef enum {
CAMERA_FB_IN_PSRAM, / *! <Frame buffer is placed in external PSRAM * /
CAMERA_FB_IN_DRAM / *! <Frame buffer is placed in internal DRAM * /
} camera_fb_location_t;
I added one line to the cameraWebServer program as a trial.
// if PSRAM IC present, init with UXGA resolution and higher JPEG quality
// for larger pre-allocated frame buffer.
if (psramFound ()) {
config.frame_size = FRAMESIZE_UXGA;
config.jpeg_quality = 10;
config.fb_count = 2;
} else {
config.frame_size = FRAMESIZE_SVGA;
config.jpeg_quality = 12;
config.fb_count = 1;
config.fb_location = CAMERA_FB_IN_DRAM; // add 2021-12-09
}
I checked the operation of UNIT CAM.
