petalinuxbuild

petalinuxbuild is a command-line utility within the Xilinx PetaLinux workflow used to build the software images for a PetaLinux project. It orchestrates the Yocto-based BitBake build system to assemble a Linux kernel, device tree, boot loader, and root filesystem configured for the target Xilinx hardware. The exact set of images produced depends on the project configuration, including machine settings, kernel options, and filesystem layout.

Usage and workflow: A project is created with petalinux-create and configured with petalinux-config. After configuration, a full build is started by running petalinux-build in the project directory. The command can target specific components with the -c option, for example petalinux-build -c kernel, petalinux-build -c rootfs, or petalinux-build -c images. The build process compiles cross-compiled binaries and assembles boot artifacts appropriate for the target hardware. The resulting artifacts are suitable for deployment on devices such as SD cards or other boot media.

Output: On successful completion, petalinux-build writes artifacts to the project’s images directory. Typical outputs include a kernel image, a device tree blob, boot-related files, and a root filesystem in a chosen format. These components can be combined into a bootable image set for the target board or packaged for distribution via other PetaLinux tools.

Notes: petalinuxbuild is part of the PetaLinux toolchain and relies on the host system’s environment and the board support package configured in the project. It is commonly used for embedded Linux development on Xilinx devices, including Zynq-7000 and Zynq UltraScale+ MPSoC families.
