The petalinux-package --prebuilt command creates
a new directory named “pre-built” inside the directory hierarchy of the specified
PetaLinux project. This directory contains the required files to facilitate booting a
board immediately without completely rebuilding the project. This workflow is intended
for those who will later create a PetaLinux BSP file for distribution using the petalinux-package --bsp workflow. All
Xilinx®
reference PetaLinux BSPs contain a prebuilt
directory.
