11.2 IPMC Upgrade
The IPMC component is fully HPM.1 compatible and contains three elements as shown on the
figure below.
There are images for the boot loader and the firmware. There is also a combined image
containing the boot loader and the firmware. The Boot loader update should only be done if it's
required.
The boot loader does not perform any upgrade action. The boot loader is able to boot either of
two redundant copies of the firmware in the flash depending on the current value of the special
partition status byte that is stored in the internal IPMC EEPROM. The boot loader can fall back
to the backup copy by booting the alternate partition. The boot loader manages two firmware
partitions; the active and backup partition. It is responsible for detecting if the active firmware
is invalid or has failed. If the active firmware failed or is invalid, the Boot loader will switch to the
backup partition. When switching, the partitions change their roles. Switching of the partitions
also takes place when the firmware is upgraded and activated using the HPM.1 upgrade
procedure.
The firmware image is the regular firmware and change with every update.
