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 RSU image. To ensure reliable operation, the Programming File Generator creates two copies of the sub-partition table (SPT0 and SPT1) and the configuration pointer block (CPB0 and CPB1).
The initial RSU image stored in flash typically contains the following partitions:
Sub-partition Name | Contents |
---|---|
BOOT_INFO | Decision firmware and decision firmware data |
FACTORY_IMAGE | Factory Image |
SPT0 | Sub-partition table 0 |
SPT1 | Sub-partition table 1 |
CPB0 | Pointer block 0 |
CPB1 | Pointer block 1 |
P1 | Application image 1 |
P2 | Application image 2 |
- SPT0 and SPT1 point to everything:
- BOOT_INFO
- Factory Image
- Pointer Block 0 and Pointer Block 1
- All Application Images
- Pointer Block 0 and Pointer Block 1 point to all Application Images
- You do not need to know the addresses of the decision firmware, decision firmware data, and factory image.
- You have access to the sub-partition tables. The sub-partition tables provide access to the data structures required for remote system update.
