Hello

I was just talking to a person from Nvidia in their forums and he informed me that the CSI ports on the Jetson Xavier NX Developer Kit can be converted from 2-lane to 4-lane (link) and that means that it should be possible to connect 2x Arducam 12MP IMX477 Motorized Focus High Quality Camera for Jetson Nano/Xavier NX . If they are connected as master/slave would that make them suitable for stereo vision at 12MP@60fps? Can anyone verify this? What changes must be made to the drivers to support a setup like this?
7.What attempts at troubleshooting have you already made?

8.How would you like us to help you?

Hi there,

We have verified the 12MP@60 of a single camera, but it needs to use a third-party carrier board (because the official carrier board only has 2lanes)

In this thread the person from Nvidia says that the buses can be changed to 4 lanes by changing a command to:

bus-width = <4>;

Hi @serstel

The CSI2 interface of the official carrier board is only 2-lane, so just modifying the driver and device tree is not enough.
And we currently do not plan to release a 4-lane version of the camera driver, but we accept customization.
