Please elaborate what “test pattern generator” you want to use here…
At least tell us what interface you want to use.

TPG of the CSI unit.

hello ashik.p,

may I know which JetPack release you’re working with?
the latest JetPack release (i.e. JetPack-4.4 GA) should have nvhost-tpg to enable that.
here’re steps for your reference.

1) sudo insmod /lib/modules/`uname -r`/kernel/drivers/media/platform/tegra/tpg/nvhost-vi-tpg.ko
2) export DISPLAY=:0
3) argus_camera -d <num> --kpi 
# is video node in /dev/video#, video6 is normally a TPG node.
