5.3 Firmware Upgrade

The standard way to upgrade the MMC's operational code is to use the open tool “ipmitool” (see

Table 2, Related Publications). This tool allows download and activation of the new operational

code and also a rollback to the “last known good” operational code. Additionally, the status and

the firmware version of the firmware copies can be checked.

For local or remote firmware upgrade, the following IPMI interfaces are available:

• KCS interface (local, requires active payload, but fast)

• IPMB (remote, independent of the payload state)

During the download process, the currently running operational code operates as usual until

the activation command is issued. During the activation process, the MMC is off-line for about

20 seconds while the boot code is re-organizing the firmware storage. Afterwards, it starts the

new operational code. If this doesn't succeed, after a timeout the boot code performs an auto-

matic rollback to the “last known good” operational code.

5.3.1 Firmware File Formats

Firmware images for upgrade are provided in two formats:

• Firmware in binary format, e.g. FW_IPMI_<BOARD>_<REL>_FWUM.bin,

for usage with “ipmitool fwum ..” commands

• Firmware images in the PICMG defined HPM.1 file format,

e.g. FW_IPMI_<BOARD>_<REL>_FWUM.hpm,

for usage with “ipmitool hpm ..” commands

where:

<BOARD> indicates board family of the MMC’s firmware

<REL> indicates release (version) of MMC’s firmware

Note ...

To upgrade the IPMI firmware and to obtain its version, the U-Boot “fwum”

command can be used. For further information, refer to the AM4150 U-Boot

Bootloader User Guide.
