MMC Firmware Update
5.2.1
MIC-5602 Field Upgradeable Components
The MIC-5602 Processor AMC board provides HPM.1 compliant in field updates,
supporting a total of four components:
1) MMC Boot Loader
2) MMC Firmware
3) x86 BIOS
4) LAN EEPROM
The HPM.1 update works through the IPMB capable interface such as IPMB-L.
5.2.1.1
MMC Boot Loader
Located at the end of the program memory space (on-chip flash memory) of the AVR
microcontroller is a small software component, called the boot loader. This compo-
nent has several important tasks to perform for the MMC boot process. As the boot
loader is not rollback capable, it can potentially be damaged through a failed upgrade
operation. Hence, Advantech do not plan to release boot loader updates to custom-
ers.
5.2.1.2
MMC Firmware
The active MMC firmware (application) is located at the beginning of the program
memory space. The AVR on-chip flash holds two firmware (FW) copies, an active
one as well as a backup one, providing roll back features in case of failed FW
upgrades. Advantech will provide bug fixes, updates and new features through FW
application images.
5.2.1.3
x86 BIOS
The FWH chip contains two BIOS images. The first copy is treated as the default
image, and the second one as roll back copy for error recovery and fail safe booting.
Upgrading of the BIOS firmware requires dedicated support by OS level software on
the x86 system.
Known Limitation:
At the time of the manual creation, the dual BIOS upgrade
utility is not yet available.
5.2.1.4
LAN EEPROM
The LAN EEPROM only contains a single image; meaning it is a HPM.1 compliant
component without rollback support therefore extreme caution should be exercised
when upgrading the LAN EEPROM component. Upgrading the LAN EEPROM image
requires dedicated support by OS level software on the x86 system.
Note!
At the time of the manual creation, this feature has not been imple-
mented in the MMC firmware.
