hello DavidSoto-RidgeRun,
please check this, Ganged mode does not work with HDMI input via CSI - #5 by JerryChang
Multi-brick streams (i.e. gang mode) is NOT implemented for Xavier series VI driver.
there’s limitation for the CSI bandwidth, 40-Gbps (2.5Gbps/lane) in DPHY; CPHY will have larger bandwidth, 109-Gbps.
regarding to the ISP capability, it has the max line buffer width as 6144.
