2.5.4 MMC Firmware Code
MMC firmware code is organized into boot code and operational code, both of which are stored in internal
flash memory. 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 that the firmware operates correctly.
Upon successful verification of the operational code checksum, the firmware will jump to the operational
code.
2.5.5 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 upgradeable
through any IPMI interface without payload impact.
2.5.6 Hot-Swap Process
The RTM8242 has the ability to be hot-swapped in and out of the front board. The onboard MMC manages the
RTM's power-up and power-down transitions. The list below illustrates this process for power down request.
1 Ejector latch is opened. MMC firmware detects the event.
2 MMC sends "Module Handle Open" event message to the front board. The corresponding M state of
the RTM moves from M4-> M5.
