Generating boot.bin

📘

Note

This tutorial assumes you've created the First Stage Boot Loader from our tutorial.

Required Files

The first step of making a custom boot.bin file is acquiring the following three files:

• fsbl.elf - generated by Xilinx SDK, previously built in Create the First Stage Boot Loader
• ocpoc_rev1.bit - generated by Vivado, previously built in Configure/Create OcPoC
• uboot.bin - provided, or generated by U-Boot Generator

Required Software:

• Xilinx Vivado(minimum version of 2015.4)
• Xilinx SDK(minimum version of 2015.4)
• Device Tree Generator - checkout the same branch as your version of Vivado
• U-Boot Generator - checkout the same branch as your version of Vivado

Generating the 'boot.bin'

1. Open the Xilinx SDK 2015.4.
2. Choose Xilinx Tools -> Create Boot Image

3. The path of the Output BIF file should be the directory of the generated boot.bin.
   Click add -> Browse
4. Select the three required files (noted at the top of this tutorial) and click OK. The Add order is: fsbl.elf, ocpoc_rev1.bit and uboot.bin.

5. Now click Create Image and the boot.bin file will be generated.
