If you select boot component generation in platform generation, the Vitis tool creates FSBL applications within the platform component. To modify the source code of these applications, follow the steps below.
  1. To modify the source code for FSBL, go to the corresponding platform and expand the Source.
  2. Expand the zynqmp_fsbl_bsp folder and modify the source files inside.
  3. Save your changes and rebuild the platform with the new changes.
    Note: To reset domain/BSP sources anytime, click the Regenerate BSP option on the Board Support Package overview page.
Note: An alternative way to update the FSBL and PMUFW source code is in Modifying the Domain Sources (Driver and Library Code).
