The HPM.1 command, Activate Firmware does not reboot the payload firmware
unconditionally. Instead the blade can be power-cycled gracefully to activate the new
firmware.
9.2.1.4 BIOS Component
The ATCA-7480 provides two SPI flashes for storing two redundant BIOS firmware images; one
is called "Active", the other one is "Backup". Due to the fact that the "Active" SPI flash is routed
to the Intel CPU always, the IPMC can perform HPM.1 specific firmware upgrades only to the
"Backup" SPI flash.
The information about which BIOS flash is actually active, is provided using the Boot Bank
Supervision Sensor. For details, see
Boot Bank Supervision Sensor on page 304 . Besides HPM.1
manual rollback, there is also a possibility to switch the banks without upgrading an HPM.1
firmware at all. For details, see
System Boot Options Commands on page 233 .
Automatic rollback is implemented via failsafe architecture. For details, see Fail Safe Logic on
page 316 .
The HPM.1 command, Activate Firmware does not reboot the payload firmware
unconditionally. Instead the blade can be rebooted gracefully to activate the firmware.
Crisis recovery is supported fully (two broken SPI flashes can be reprogrammed via IPMI with
the help of the ShMM).
9.2.2 Retrieving Versioning Information
Retrieving the actual and backup version of the components is possible without switching
payload firmware boot banks (Artesyn Embedded Technologies Embedded Computing
strongly recommends to use fcu for embedded firmware upgrades). The following terminal
output illustrates the component versions as an example:
A payload cold reset is not enough to execute a new FPGA component. In this particular case
a power cycle is required.
