5.1.3. OCTEON U-Boot Redundancy
The OCTEON U-Boot image is stored in a NOR flash memory. On the aTCA-N700,
each NP has two of such U-Boot flash memories in a primary and a redundant fashion.
The flash device selection is done by the CPLD and configurable by a CPLD register on.
Shown below is a command example of such setting.
[ NOR_FLASH1 for NP-A (top) ]
root@aTCA-N700:~#
nbm-cpld flashctl @npa 0 <- select
NOR_FLASH1(bank#0) for NP-A

[ NOR_FLASH2 NP-A (top) ]
