3.2.3. 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 the OS files.

Depending on the boot stage that performs the FPGA configuration, you have the following options for storing the FPGA core and I/O configuration file:

  • An SDM flash storage partition—In this case the SSBL initiates configuration
  • In the OS file system—In this case the OS initiates configuration
Table 7.  Supported Single SDM Flash Sources

In order for the software running in the HPS (for example, the FSBL and SSBL) to access the flash attached to the SDM, it must request permission from the SDM.

In the Quad SPI flash example, the SSBL, OS and file system reside in the Unsorted Block Image File System (UBIFS).
