How to check MIPI CSI error in Orin?

hello jw.cs.park,

you may check registers to obtain more CSI details.
for example,
NVCSI_STREAM_0_PH_WC_0, or NVCSI_STREAM_0_PF_CRC_0

you should enable camera stream before access registers.
moreover, there’s firewall configuration of accessing to these registers on Orin platforms.
you may refer to Topic 234321 for CBB FIREWALL settings, please update tegra234-mb2-bct-scr-p3701-0000-override.dts then re-flash your target to apply the config.
