Modifying Source Code for FSBL and PMU Firmware

When boot component generation is selected in the platform generation phase, FSBL and PMU firmware applications are created within the platform project. To modify the source code of these applications, follow the steps below.
  1. To modify the source code for FSBL or PMU firmware, go to Explorer view and expand the corresponding platform.
  2. Expand the boot domain folder and modify the source files inside.
  3. Save your changes and click the button to build the boot components with the new changes.
    Note: To reset domain/BSP sources anytime, click the Reset BSP Sources option on the Board Support Package overview page.
    Note: An alternative way to update the FSBL and PMUFW source code is to follow the instructions in Modifying the Domain Sources (Driver and Library Code).
