  • Done!

Build The PetaLinux Distribution

Create a new project

  • Setup PetaLinux Environment
    $ cd <petalinux-install-directory>
    $ source peta/settings.sh
    
  • Create Project from Ultra96 BSP
    $ petalinux-create -t project -s <path-to>/xilinx-ultra96-reva-v2018.2-final.bsp
    

Start the Build

$ cd xilinx-ultra96-reva-2018.2/
$ petalinux-build
  • Grab a cup of coffee… this might take a while.

Create BOOT.BIN

$ petalinux-package --boot --fsbl components/plnx_workspace/fsbl/fsbl/Release/fsbl.elf --fpga hardware/xilinx-ultra96-reva-2018.2/xilinx-ultra96-reva-2018.2.runs/impl_1/design_1_wrapper.bit --pmufw components/plnx_workspace/pmu-firmware/pmu-firmware/Release/pmu-firmware.elf --u-boot

Flash micro-SDCard

**All files required for this step will be present at /images/linux/ once the build is completed**

  • Format the SD Card with the following layout. To do this you can use tools such as fdisk, GParted, gnome-disks etc.
    • Partition 1:
      • Format: FAT32
      • Size: 1GB
      • Label: boot
    • Partition 2:
      • Format: ext4
      • Size: 4GB or more
      • Label: rootfs
  • Copy Boot files
    $ cd <project-dir>/images/linux/
    $ cp BOOT.BIN <mount-point-for-boot>
    $ cp image.ub <mount-point-for-boot>
    
  • Flash rootfs Partition
    $ sudo dd if=rootfs.ext4 of=/dev/sdX2
    $ sync
    

Once the installation is complete safely remove the sdcard and insert into your Ultra96 and power-on, you should see PetaLinux boot.
