How to dump Xavier MIPI controller register or other Peripheral module register through linux?

I want to check Xavier MIPI contrlller rx status through linux, can you tell me methods ?

hello 413940089,

may I have more details about what’s the status you would like to check.
suggest you download [Xavier Series (SoC) Technical Reference Manual] from Jetson Download Center and check NVCSI registers

hello JerryChang,

 I want to dump Xavier MIPI contrlller register  when  Xavier system (Ubuntu) startup  [b]for debug VIDEO input[/b]

For example, what Linux command can I use to view register, when app is running in Xavier

hello JiaZW,

there are 3rdparty tools such as devmem2 or i2cget to check register values.
you may also check the register address in the [Xavier TRM].

hello JerryChang,

I still need to ask you a question about VI register!!

Why I check VI register (0x0x15c14034,0x15c14038,0x15c1403c) through devmem tools,

all return 0xBADF5100 ?????

It’s a little abnormal

hello JiaZW,

you may also check register description for details,
for example, VI_CFG_VGP*.

may I know are you able to access camera sensors?
here’s v4l2-ctl command for your reference, thanks

$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100
