4.12. QSPI Controller Ownership Selection Impact on the HPS Software
4.7. Configuration over AVST
An external initiator sends the configuration data to the device over an Avalon® Streaming Interface bus. There is one supported width for the Avalon® Streaming Interface bus: AVST x8.
Note: On Configuration over AVST, the QSPI access from the HPS software is not supported and the QSPI component must be disabled in both the bootloader (for example: U-Boot configuration and device tree) and the OS (for example: Linux* device tree).
