hello f.ortolano,
that’s correct. assume you’ve two 4-lane camera connected to and sharing the same CSI brick, you should have same port-index and bus-width settings for both of them, but using vc-id to distinguish difference cameras.
note,
there’re vc-id for destination ID assigned to sensor, and vc_id property in sensor mode, they should be within the same settings. you must set the vc-id property in the gmsl-link node for each sensor to match the vc_id property in the sensor mode device node.
