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.
