Functional Description
The IPMC flash comprises two components:
IPMC Firmware Updates
Update Modes
There are two update modes:
• Internal Flash on IPMC – 512 KB of memory. Used to store the primary firmware
• External Flash Memory – External 2 MByte flash memory. The external flash
• Direct Mode – This upgrade procedure happens when the user updates the IPMC
image. It consists of boot block and operational code (known as the execution

to back up the “old” operational image.

— Operational Code – This area contains the active operational code. Which is

— Partition B (Rollback Region) is used to store a backup copy of the original
operational code (opcode). This is a recovery block and not updated in the field.
