Hi Experts,
There is a warning trace when booting up Orin NX board with Jetson 6.2, Linux 36.4.3
I connect a 4K HDMI monitor with the DP port of Orin NX board.
[ 11.525920] NVRM nvAssertFailedNoLog: Assertion failed: minRequiredIsoBandwidthKBPS <= clientBwValues[DISPLAY_ICC_BW_CLIENT_EXT].minRequiredIsoBandwidthKBPS @ kern_disp_0402.c:111

BTY, if I change another monitor or another DP-to-HDMI cable, the warning trace may disappear, but there is another error as below
[ 12.752477] NVRM rpcRmApiControl_dce: NVRM_RPC_DCE: Failed RM ctrl call cmd:0x731341 result 0xffff:
Because the driver is very complicated, I can not handle it in short time.
So, could you please help to check it, and give me some advice to fix it?
thanks,
LImeng
