I2c access in the UEFI shell

bkingsbury — Wed, 17 Feb 2021 22:16:22 GMT

I am attempting to access the I2c bus from efi code that runs from the UEFI shell. This is on an adlink cExpress-wl module with a 8th Gen Intel® Core™ i7-8665UE . I am looking for the low level UEFI code to access the I2c over the PHC.

Thanks

Brian
