9.13.2. Using a Single flash for Both FPGA Configuration and HPS Mass Storage
The QSPI device connected to the SDM can also be accessed directly by the HPS. However, there is a significant speed penalty when doing so. It is up to you to decide whether the speed penalty is acceptable for the end application.
For reference, here are some performance numbers:
- Maximum HPS eMMC read speed: 50Mbytes/s
- Maximum HPS SD read speed: 25Mbytes/s
- Maximum HPS read speed from SDM QSPI: 4Mbytes/s
