[OA-syst-ref] Xilinx BOOT.BIN with bif file Generation documents

Hi Bill,

Following documents / User Guide can help to understand how BOOT.BIN is generated.

1. Petalinux Tools Userguide: https://www.xilinx.com/content/dam/xilinx/support/documentation/sw_manuals/x... * Page – 31 explains how to generat BOOT.BIN using petalinux (petalinux-package tool) * Internally it should be using bootgen utility 2. Bootgen userguide : https://www.xilinx.com/content/dam/xilinx/support/documentation/sw_manuals/x... * This user guide explains whole bif (boot image format) file format (Page – 45) * It also explains how to use bootgen command.

i. In general I use something like following to generat BOOT.BIN:

bootgen -arch <platform name> -image boot.bif -w -o BOOT.BIN

Platform name could be: zynq, zynqmp or versal

We mention all the images’ path in bif file, i.e. fsbl, ATF, u-boot etc.. and bootgen can combine them all in one BOOT.BIN file and we can use that BOOT.BIN to boot to u-boot. In Yocto this is taken care by Vitis xsct tool. So we don’t have to generate it manually.
