14.5 EDK - FSBL hangs when I try to boot an application that is linked to the PL system


If I create an application (ELF) that is linked to memory that is controlled by the PL (e.g., BRAM, MIGs DDR), the FSBL hangs when downloading the application, even when DONE goes High.


The 14.5/2013.1 version of the FSBL tries to download the user application before the level-shifters to the PL are enabled, thereby hanging the system.

To work around this issue:

  1. Open the fsbl_hooks.c file in the FSBL project.
  2. Change the function FsblHookAfterBitstreamDload() to the code listed below:
u32 FsblHookAfterBitstreamDload(void)
	u32 Status;

	Status = XST_SUCCESS;

	 * User logic to be added here.
	 * Errors to be stored in the status variable and returned
	fsbl_printf(DEBUG_INFO, "In FsblHookAfterBitstreamDload function \r\n");

	return (Status);
