PetaLinux is an embedded Linux Software Development Kit (SDK) targeting FPGA-based system-on-a-chip (SoC) designs. This guide helps the reader to familiarize with the tool enabling overall usage of PetaLinux.
You are assumed to have basic Linux knowledge, such as how to run Linux commands. You should be aware of OS and host system features, such as OS version, Linux distribution, security privileges, and basic Yocto concepts.
The PetaLinux tool contains:
- Yocto Extensible SDK (eSDK )
- XSCT (Xilinx Software Command-Line Tool) and toolchains
- PetaLinux CLI tools
PetaLinux SDK is a Xilinx development tool that contains everything necessary to build, develop, test, and deploy embedded Linux systems.
Yocto Extensible SDK
The following table details the four extensible SDKs installed.
| Path | Architecture |
|---|---|
| $PETALINUX/components/yocto/source/aarch64 | Zynq® UltraScale+™ MPSoC and Versal® ACAP |
| $PETALINUX/components/yocto/source/arm | Zynq-7000 devices |
| $PETALINUX/components/yocto/source/microblaze_full | MicroBlaze™ ™ platform full designs |
| $PETALINUX/components/yocto/source/microblaze_lite | MicroBlaze platform lite designs |
petalinux-config or the petalinux-build command in the PetaLinux project. The
project extracts the corresponding eSDK, for example, if you create a Zynq UltraScale+ MPSoC project, then only the
aarch64 eSDK is extracted into the <plnx-proj-root>/components/yocto project.XSCT and toolchains
For all embedded software applications (non-Linux), the PetaLinux tool uses XSCT underneath. The Linux toolchain for all three architectures is from Yocto.
PetaLinux Command Line Interface (CLI) tools
This contains all the PetaLinux commands that you require. The CLI command tools are:
-
petalinux-create -
petalinux-config -
petalinux-build -
petalinux-util -
petalinux-package -
petalinux-upgrade -
petalinux-devtool -
petalinux-boot
