How to write i2c device registers before pcie driver load on jetson xavier AGX

hi all

I have one pcie re-driver for enlarge signal .I need to write the below value
"i2ctransfer -f -y 7 w5@0x51 0x03 0xd0 0xc4 0x7c 0x7c "
to i2c re-driver device before PCIE driver load during system boot up.
can you teach me how to do it? or can give me the sample code?

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

yes,still need the support

I don’t have a good idea for this. Not sure why that is required.

Maybe you rescan or rebind the pcie driver again after your i2c write is done?

I already know how to do it ,thank you.
