  1. How many cameras can the Jetson-Xavier support?
    We have a new project that needs to connect 8 cameras,
    Can Jetson-Xavier connect 8 cameras?

  2. What do “CSI_5(note)” and “CSI_7(note)” mean?

Thank.

Basically only can support 6 physical connect to tegra. However with virtual channel you can connect to 12 sensors with serdeser/gmsl bridges.
