My m5stack camera F not work, when check JPEG header.

camera.c file line 724

       //check for correct JPEG header
        if(s_state->sensor.pixformat == PIXFORMAT_JPEG) {
            uint32_t sig = *((uint32_t *)s_state->fb->buf) & 0xFFFFFF;
            if(sig != 0xffd8ff) {//sig always 0xffd9ff
                s_state->fb->bad = 1;
                return;
            }
        }

Is it a hardware problem? If not how to fix it?

Maybe software problem, Try test https://docs.m5stack.com/#/en/unit/m5camera_f?id=easyloader, if it works well, pls describe the software used if works wrong, it`s hardware problem
