2.7.4 MMC Firmware Code
MMC firmware code is organized into boot code and operational code, both of which are stored in a flash
module. Upon an MMC reset, the MMC executes the boot code and performs the following:
1 Self test to verify the status of its hardware and memory.
2 Performs a checksum of the operational code.
3 Set operational state that tells the boot block the firmware operate correctly.
Upon successful verification of the operational code checksum, the firmware will jump to the operational
code.
2.7.5 MMC Firmware Upgrade Procedure
The upgrade procedure is compliant to PICMG HPM.1. MMC Firmware upgrades can be done by using IPMITOOL
from
sourceforge from the front board or remotely on the chassis. It has been designed to be upgradable
through any IPMI interface without payload impact.
