The boot process can be based on a primary boot device such as SD, eMMC, QSPI, OSPI, JTAG, or SelectMAP, and UFS (Only for Versal AI Edge Series Gen 2 and Versal Prime Series Gen 2 devices). At POR or system reset, the boot process starts with the primary boot:

BootROM
  • Reads the boot mode register to determine the primary boot device
  • Loads the PLM from the specified primary boot device into the PPU RAM
  • Releases the PPU to execute the PLM
PLM
Loads remainder of PDI content (Images and partitions) from the primary boot device.
