ATCA-7490 Installation and Use (6806800U11F
)
348
The IPMC provides an OEM command called
Set/Get Serial Output
to be used to
influence this serial interface routing default. The serial line selection is implemented non-
persistently to ensure that the serial interfaces always can be accessed easily after power-up.
9.12 BIOS Boot Bank Selection
The ATCA-7490 provides redundant payload boot flashes for manual and automatic crisis
recovery.
The general concept is that there is always an active and a standby SPI flash device. The role of
the two devices can be reversed by the FPGA; for this to work, the FPGA has to drive the chip
select signals to the SPI flashes. The final decision on which of the two devices is active and
standby is done by the IPMC.
The BIOS Boot Bank Selection is implemented such that swapping the SPI flashes is not in effect
immediately. To ensure that the active BIOS bank cannot be overwritten at all (BIOS upgrades
always can just access the backup boot bank), the boot bank selection is masked with a
payload reset. Therefore, swapping the boot bank is possible with the following steps only:
Swap the BIOS boot banks
Reset the payload
The IPMI command,
Set/Get System Boot Options
together with the parameter #96
can be used to specify the BIOS boot bank from which the payload shall boot from persistently.

9.12.1 Boot Bank Sensor
The ATCA-7490 provides a Boot Bank Sensor, illustrating from which BIOS Boot Bank the boot
firmware has last booted. For details, see
.
Be aware that swapping the BIOS boot bank is active only after payload reset.
