Enables the camera four times

[edward18]

I used the official nano development kit.

The csi interface should be 7 and 8.
But now there is a problem.

hello edward18,

may I know what’s camera module you’re using?
that’s not actual 4-times to enable same camera, it’s looking for imx219 at four different i2c buses but all return with probing failure.

@JerryChang

It’s arducam’s imx219.
Under normal circumstances, shouldn’t the nano read the 7 and 8 interfaces?

hello edward18,

as you can see, there’s cam_i2cmux which used to share the same i2c address for different cameras.
if you’re using multiple cameras, please check you’ve enable i2c mux also.

@JerryChang

I understand what you mean, but the i2c mux is already equipped in the official imx219 configuration and I didn’t make changes.

@edward18

It’s arducam’s imx219.

hello edward18,

camera vendor should also share source package, or release image for validation.
could you please also contact with them for confirmation. thanks
