What is the use of FSBL?
First Stage Bootloader (FSBL) for Zynq UltraScale+ MPSoC configures the FPGA with hardware bitstream (if it exists) and loads the Operating System (OS) Image or Standalone (SA) Image or 2nd Stage Boot Loader image from the non-volatile memory (NAND/SD/eMMC/QSPI) to Memory (DDR/TCM/OCM) and takes A53/R5 out of reset.

The First Stage Bootloader reads software images from flash memory, utilizing redundant copies of the images, and launches the operating system. This bootloader finds a valid copy of the OS image and the ram filesystem image in flash memory.
How do I create a ZYNQ boot image?
Currently, boot image creation for Zynq and Zynq UltraScale+ MPSoC architectures is supported. Select Create a new BIF file….Creating a Boot Image
- Select the Partition type as “bootloader”.
- Select the FSBL “zynq_fsbl. elf” path.
- Select the authentication as rsa and encryption as aes.
What is QSPI32?
I created it because I couldn’t find this information from a few Google searches. TL;DR. QSPI24 means 24-bit addressing which also means 3-byte address mode and that QSPI32 means 32-bit addressing which also means 4-byte address mode.
