Access Intel ME IPMB from BMC

[CS20 CHMa0]

Hi Oskar,
You can reference Intel node manager for send IPMB command example.
https://github.com/Intel-BMC/node-manager/blob/master/NodeManagerProxy.cpp

And you can get more information about how IPMB work by following link:

Thanks,

Subject: Access Intel ME IPMB from BMC

Hi everyone

I'm trying to find out how I can access the Intel ME via IPMB from the BMC (OpenBMC).

From what I gathered, Intel ME's IPMB is on the PCH's SMLink0. I know this is connected to one of the SMBus modules on my AST2500. But what I can't find out is how I actually send commands there? I'm sure I'm missing a document that makes this obvious.

Or is it as simple as dropping IPMI packets onto the bus?

Is this by any chance already implemented in OpenBMC?

Thanks for any hints!

Oskar
