Glue Logic FPGA Flash Selection
The ATCA-747x provide redundant FPGA flashes for manual 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 IPMC, for this to work the IPMC has to drive the chip
select signals to the SPI flashes. The final decision which of the two devices is active and
standby is done by the IPMC.
The FPGA Bank selection is implemented such that swapping the SPI flashes is not in effect
immediately. To ensure that the backup FPGA bank is loaded (FPGA upgrades always can just
access the backup bank), the payload need to be power-cycled. Therefore swapping the FPGA
bank is possible with the following sequence only:
1. Swap the FPGA banks
2. Power-cycle the payload
The IPMI command Set/Get System Boot Options together with the parameter #96 can be
used to specify the FPGA boot bank from which the payload shall boot from persistently, for
