Hi @KenToku

check this:

1MP*4 Quadrascopic Monochrome - VIDIOC_DQBUF: Resource temporarily unavailable

If the green LED of the HAT flashes normally, it proves that the HAT is normal. Now there may be a problem with the cable link of one of the four cameras, or the camera is damaged. Would you take a photo for me to confirm?
