Mipi-csi video interface on Nano carrier board B01

Hello, forum

I have a pre-configured mipi csi video output(4-lanes) and want to connect it to JetsonXavierNX work with Nano’s carrier board B01, B01 have two camera interface and both are only 2-lanes,could I use all of the two camera interface for a 4lane mipi input?

No, it is CSI0 & CSI2 to the two camera connectors, they can not be combined as one 4-lane port.
