Writing UEFI application for UpXtreme

Ruvimp — Wed, 06 Jul 2022 23:26:12 GMT

I am writing a UEFI application to access I2C on an UpXtreme. The pins are within CN26 (docking II), but I do not see a way to access them. I am using edk2 with the whiskeylake - upxtreme package.

Is there any way to access the pins directly or maybe the registers that are associated with?

Hello, @Ruvimp:

Thanks for your clarification.

You need to contact your Intel BIOS Vendor (IBV) because the UEFI is distributed and supported by each BIOS vendor, they have their own information on their channels of support, and even i2c is an open standard. They should provide as a reference something similar to the information stated on the following website:
