First, source the appropriate environment file for PetaLinux 2019.1; something like:

$ source .../2019.1/settings.sh
$ echo $PETALINUX
/home/rpjday/xilinx/2019.1
$

followed by creating a new (for this discussion, zynqMP-based) PetaLinux project and moving to that new project directory:

$ petalinux-create \
  --type project \
  --name ultra96v2 \
  --template zynqMP
$ cd ultra96v2

Configure the new project by running petalinux-config and incorporating the aforementioned .hdf file by referring to its directory location:

$ petalinux-config --get-hw-description <dirname of HDF File>

at which time you will be placed in the PetaLinux “System Configuration” utility; if you have nothing to change, simply exit and save your configuration.

$ petalinux-config
$ petalinux-config -c bootloader   [virtual/fsbl]
$ petalinux-config -c u-boot
$ petalinux-config -c kernel
$ petalinux-config -c rootfs
$ petalinux-config -c busybox
$ petalinux-config -c pmufw
$ petalinux-config -c device-tree

Now that all of the project configuration is complete, kick off the PetaLinux build with:

$ petalinux-build

A successful build should generate numerous build artifacts under the project's images/linux/ directory, depending on how the project was configured:

$ ls images/linux/
bl31.bin     rootfs.cpio.bz2        rootfs.its            system.dtb
bl31.elf     rootfs.cpio.gz         rootfs.jffs2          System.map.linux
Image        rootfs.cpio.gz.u-boot  rootfs.manifest       u-boot.bin
image.ub     rootfs.ext3            rootfs.tar.bz2        u-boot.elf
pmufw.elf    rootfs.ext3.bz2        rootfs.tar.gz         vmlinux
rootfs.bin   rootfs.ext4            rootfs.testdata.json  zynqmp_fsbl.elf
rootfs.cpio  rootfs.ext4.gz         system.bit
$

The final step in the PetaLinux build is to “package” the appropriate generated artifacts to copy to a bootable SD card to boot the target system (in this case, a Fidus Sidewinder). The simplest SD card image will contain two files:

• BOOT.BIN
• image.ub

The FIT image file image.ub should already have been generated; to complete the process, build the BOOT.BIN file with:

$ petalinux-package \
  --boot \
  --force \
  --format BIN \
  --fsbl images/linux/zynqmp_fsbl.elf \
  --fpga images/linux/system.bit \
  --u-boot
$

whereupon you can see the target boot file BOOT.BIN being constructed, generating output something like:

INFO: File in BOOT BIN: ".../myproj/images/linux/zynqmp_fsbl.elf"
INFO: File in BOOT BIN: ".../myproj/images/linux/pmufw.elf"
INFO: File in BOOT BIN: ".../myproj/images/linux/system.bit"
INFO: File in BOOT BIN: ".../myproj/images/linux/bl31.elf"
INFO: File in BOOT BIN: ".../myproj/images/linux/u-boot.elf"
INFO: Generating ZynqMP binary package BOOT.BIN...

You can optionally create a .bsp file for import into a future PetaLinux project with:

$ petalinux-package \
  --bsp \
  --project . \
  --output myproj.bsp
