A.2.2.1. Feature Availability under SDM/HPS Ownership of Quad SPI Controller
This includes operations such as retrieving items from the QSPI, like the Linux file system, an encryption key, phase 2, partial reconfiguration FPGA image, and others. If the SDM has ownership of the QSPI controller, the HPS cannot access the QSPI device for reading or writing, and vice versa.
The following table describes the QSPI controller ownership requirement for different device functionalities.
Device | Feature/Application (QSPI Ownership: HPS/SDM must own) |
||||||
---|---|---|---|---|---|---|---|
HPS loading from QSPI flash | HPS loading Phase2 bitstream | HPS loading Partial Reconfiguration bitstream | RSU from HPS | Attestation | On Boarding | BKPS | |
Agilex™ 5 | HPS | HPS: If Phase2 bitstream is in QSPI flash. SDM: If Phase2 bitstream is encrypted with AES key in QSPI flash. 74 HPS or SDM may own the QSPI controller under other scenarios following the above restrictions. |
HPS: If PR bitstream is in QSPI flash. SDM: If PR bitstream is encrypted with AES key in QSPI flash.74 HPS or SDM may own the QSPI controller under other scenarios following the above restrictions. |
