U-Boot image for ZYBO

FPGA-SoC-U-Boot-ZYBO

Overview

Introduction

This Repository provides a U-Boot Image for ZYBO.

Features

• U-Boot v2016.03 (customized)
  • Build for ZYBO
  • Customized boot by uEnv.txt
  • Customized boot by boot.scr
  • Enable bootmenu

Build U-boot for ZYBO

There are two ways

1. run scripts/build-u-boot-2016.03-zynq-zybo.sh (easy)
2. run this chapter step-by-step (annoying)

Download U-boot Source

Clone from git.denx.de/u-boot.git

shell$ git clone git://git.denx.de/u-boot.git u-boot-2016.03-zynq-zybo

Checkout v2016.03

shell$ cd u-boot-2016.03-zynq-zybo
shell$ git checkout -b v2016.03-zynq-zybo refs/tags/v2016.03

Patch for zynq-zybo

shell$ patch -p0 < ../files/u-boot-2016.03-zynq-zybo.diff
shell$ git add --update
shell$ git commit -m "patch for zynq-zybo"
shell$ git tag -a v2016.03-zynq-zybo-1 -m "Release v2016.03-1 for ZYBO"

Setup for Build

shell$ cd u-boot-2016.03-zynq-zybo
shell$ export ARCH=arm
shell$ export CROSS_COMPILE=arm-linux-gnueabihf-
shell$ make zynq_zybo_defconfig

Build u-boot

shell$ make

Copy u-boot.img, u-boot.elf and u-boot-spl.sfp to root directory

shell$ cp spl/boot.bin  ../boot.bin
shell$ cp u-boot.img    ../u-boot.img
shell$ cp u-boot        ../u-boot.elf

fpga-soc-u-boot-zybo's Issues

about vivado build the bitstream on ZYBO for U-Boot

hi
Why is there no script for compiling the Zybo bitstream in Vivado? I'm aware that it's possible to dynamically configure the FPGA's bin file (https://github.com/ikwzm/FPGA-SoC-Linux-Example-1-ZYBO). Why are the two repositories separate? For the ZynqMP, there is a script provided for compiling the FPGA bitstream (https://github.com/ikwzm/ZynqMP-U-Boot-Ultra96/tree/master).
thanks
