Firmware Upgrade Process

Upgrade Utilities
The firmware upgrade procedure is performed using the upgrade agent utility, implementing the
HPM.1 Upgrade Protocol and capable of programming custom firmware images into the flash
memory of the MMC over a serial interface or IPMB-L. Any HPM.1-compatible Upgrade Agent
can be used to upgrade the MMC firmware. It is recommended to use the
ipmitool
utility for
these purposes. The
ipmitool
utility is available from PT. Contact PT Customer Support and
Services for contact information.
The firmware image is supplied to the
ipmitool
utility in a single file called an HPM.1 upgrade
image (for information about the format of HPM.1 upgrade images refer to the HPM.1
specification).
Detailed HPM.1 Upgrade Procedure
The following images are available from PT:
•
hpm1fw.img
- this image contains the MMC firmware
•
hpm1boot.img
- this image contains the boot loader
•
hpm1all.img
- this image contains both the firmware and the boot loader
These images can be used to upgrade corresponding components of the IPMC: the firmware,
the boot loader or both.
