9.1 HPM.1
The PICMG HPM.1 (Hardware Platform Management) specification defines a standard
way of updating (MC) 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 requirements
in Telco platforms like AdvancedTCA. The Advantech IPMI Core supports HPM.1
updates over any of its IPMI interfaces.
As defined by the HPM.1 specification, the HPM.1 image contains a MD5 checksum
over the complete image. For example the IPMITool uses this checksum to verify that
the image is not corrupted. HPM.1 upgrades separate the upgrade procedure into
several phases, one of this phases is the image upload, while activation is a different
phase, see HPM.1 specification for the details.
