Quick-Build-Ubuntu-On-ZedBoard

This project provides a quick way to build Ubuntu on the Xilinx ZedBoard. This project provides compiled boot image. You don't need to compile u-boot and Linux kernel, etc.

Requirements

• Xilinx ZedBoard
• SD card ( >4GB )
• PC (running Ubuntu)

Description of directory structure

Directory	Description
boot	All necessary kernel boot files
root	Ubuntu root file system link

Build Steps

1. Download this project

   • git clone https://github.com/flsgavin/Quick-Build-Ubuntu-On-ZedBoard

2. Make SD card and adjust file and directory structure

• Insert the SD card into the PC and check the mount node

  • dmesg | tail -n 50

  The last part of the command output will indicate the node where the SD card is mounted, as shown in the figure, sdb is mounted

  Note: The following "sdb" should be replaced with your mount node (e.g. sda sdc..).

• Unmount SD card

  • sudo umount /dev/sdb1

• Erase the first sector of SD card

  • sudo dd if=/dev/zero of=/dev/sdb bs=1024 count=1

• Create SD card partition

  • sudo fdisk /dev/sdb
  • n

  n: Create a new partition 1, enter +100M in the Last sector, and the others keep the default.

  • n

  n: Create a new partition 2 and keep all defaults.

  • w

  w: Write partition table, save and exit.

3. Format partition

   • sudo mkfs.vfat -F 32 -n boot /dev/sdb1
   • sudo mkfs.ext4 -L root /dev/sdb2

4. Mount SD card

   • sudo mkdir -p /media/ubuntu/boot

   • sudo mount /dev/sdb1 /media/ubuntu/boot

   • sudo mkdir -p /media/ubuntu/root

   • sudo mount /dev/sdb2 /media/ubuntu/root

     Note: "ubuntu" here should be replaced with your user name.

5. Copy boot file to SD card boot partition

   • cd $THIS_PROJECT_PATH/boot
   • sudo cp ./* /media/ubuntu/boot

6. Build Ubuntu root file system

   • cd $THIS_PROJECT_PATH/root
   • wget https://rcn-ee.com/rootfs/eewiki/minfs/ubuntu-18.04.2-minimal-armhf-2019-02-16.tar.xz
   • sudo tar -xJvf ubuntu-18.04-2-minimal-armhf-2019-02-16.tar.xz
   • cd ubuntu-18.04-2-minimal-armhf-2019-02-16
   • sudo tar xvf armhf-rootfs-ubuntu-bionic.tar
   • sudo rsync -av ./ /media/ubuntu/root

7. Startup Ubuntu on your ZedBoard

   • Insert SD card into ZedBoard

   • Connect ZedBoard UART to PC

   • Poweron your ZedBoard

   • Open the serial software and set the baud rate to 115200

   • When serial output:

     Ubuntu 18.04.2 LTS arm ttyPS0
default username:password is [ubuntu:temppwd]
arm login:
     
     Ubuntu boot successfully!
