The Alveo Card Out-of-Band Management Specification for Server BMC documentation describes out-of-band (OoB) support implemented in the SC firmware, supporting communication with the server board management controller (BMC) over the SMBus/I2C interface on the PCIe edge connector. The underlying protocols supported are standard I2C protocol and PLDM over MCTP over SMBus.
The Card Management Solution Subsystem Product Guide (PG348) provides card management solution IP allowing you to quickly develop and interact with the satellite controller from the FPGA.
