$ 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
