In OSPI boot mode, a single OSPI flash (8-bit data bus configuration) or a dual-stacked OSPI flash (8-bit data bus configuration) can boot the device.
For additional information on the OSPI controller, see the Octal SPI Flash Memory Controller chapter.
For details on OSPI flash device support, see the Vivado Design Suite User Guide: Programming and Debugging (UG908).
Note: The Boot Search Limit section describes
the search limits.
