Dear experts

I’d like to check GMSL camera deserializer on Drive AGX board (Drive OS 5.1). I see that on i2c, the deserializer is on address 0x29. Trying to read any register from 0x29 response with error “Device or register busy”

nvidia@tegra-ubuntu:~$ sudo i2cdetect -y -r 0
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- UU -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --                        
nvidia@tegra-ubuntu:~$  sudo i2cget 0 0x29 0x11
Error: Could not set address to 0x29: Device or resource busy
nvidia@tegra-ubuntu:~$

Can you please advise?

Thanks
Tuan

Dear @v.tuanln10 ,
May I know why you want to run this command? Is it a blocker in your development?
