When I connect a V2 camera module (8 MP) to the Raspberry Pi Zero [W], I get
mmal: mmal_vc_component_enable: failed to enable component: ENOSPC mmal: camera component couldn't be enabled mmal: main: Failed to create camera component mmal: Failed to run camera app. Please check for firmware updates
I tried the tests and fixes discussed in What causes ENOSPC error when using the Raspberry Pi camera module? and they suggest a defective camera.
- The V2 works fine with the Raspberry PI 4.
- The V1 works fine with the Raspberry PI 4.
- The V1 works fine with the Raspberry Pi Zero.
- The V1 does not work with the Raspberry Pi Zero.
So I do not suspect a hardware problem.
