    How to send commands to ME using Aardvark?

    EagerXie

          As we know, in Purley platform server, if I use Aardvark which is connected to PSU-BMC I2C bus to send PMBus commands to Power Supply, if will cause server system CPU throttle. Because for PSU, there are two masters, one is Aardvark, and the other is ME. This is not convenience when system debug. How could I send commands to ME via Aardvark and then ME forward to PSU? Which I2C bus should my Aardvark connect, is it IPMB bus(SMlink0) bus between BMC and ME?  if Yes, what's the command format? For example, I want to read PMbus command code status word 79h of PSU, how could I send command to ME via Aardvark?

       

      Thanks so much.
