Syntax

bootgen -arch versal -dual_ospi_mode stacked <size>

Description

Example

This example generates two output files for independently programming to both flashes in a OSPI dual stacked configuration. The first 64 MB of the actual image is written to first file and the remainder to the second file. If the actual image is less than 64 MB, the tool generates only one file. Only the Versal adaptive SoC supports this.
