reserved 7:0
Set to zero
Note: Intel Quartus Prime patches do not change the firmware version field. All patches have the same firmware version field as the
base release on top of which the patches are applied to.
Both U-Boot and LibRSU enable the decision firmware versions to be queried. For examples on querying the decision firmware
version for both U-Boot and Linux, refer to the Remote System Update Example section. The decision firmware version must
first be queried in U-Boot for the value to be available in Linux.
5.4.1.3. RSU Image Layout – Your Perspective
The sub-partition table (SPT) is used for managing the allocation of the quad SPI flash.
The Intel Quartus Prime Programming File Generator creates the SPT when creating the initial manufacturing image. To
ensure reliable operation, the Programming File Generator creates two copies of the sub-partition table and the configuration
pointer block, SPT0 and SPT1 and CPB0 and CPB1
The initial RSU image stored in flash typically contains the following partitions:

SPT1 Sub-partition table 1
