2.2.3. Single SDM Flash

In a single flash attached to SDM layout, the flash contains all of the files required for booting, including the configuration bitstream and OS files.

Software running on the HPS such as the FSBL must request permission from the SDM to access the flash attached to the SDM.

In the Quad SPI flash example, the OS and file system reside in the Unsorted Block Image File System (UBIFS). The SSBL, which is U-Boot, resides in Raw Partition.
