HPM.1 Upgrade Support
The PICMG HPM.1 (Hardware Platform Management) specification defines a stan-
dard way of updating (BMC) firmware components over IPMI based interfaces.
Among the mechanism itself, it defines a common update file format and IPMI based
commands for the update procedure. HPM.1 is the de facto standard for firmware
updates in PICMG based environments.
Advanced features in HPM.1 address redundancy mechanisms, supporting both
automatic and manual rollbacks, to properly support the high availability require-
ments in platforms like CompactPCI.
The Advantech IPMI Core G02 supports HPM.1 updates over any of its IPMI inter-
faces. See the following tables for a list of HPM.1 components implemented on the
CPCI blade and their respective description.

3.9.1
Bootloader update
The bootloader HPM.1 upgrade is written to the LPC1768 flash directly. Means there
is no recovery existing for the bootloader image. It is not recommended to upgrade
the bootloader in the field.
3.9.2
Firmware upgrade
The firmware upgrade component follows the HPM.1 specification and the upgrade
and activation stage can be performed while the payload is running. In case of an
update, the BMC is not accessible to any service while activation stage.
3.9.3
FPGA upgrade
The firmware upgrade component follows the HPM.1 specification. The upgrade can
be performed while the payload is running. For the activation stage, a payload part
reboot and power off is required. The BMC is not accessible to any service while acti-
vation stage.
3.9.4
BIOS upgrade
Like the FPGA component, the BIOS component requires a payload reboot or power
cycle, in order to perform the activation stage. The component follows the HPM.1
standard.
