This is a branch of the Eclypse Z7 board containing the Petalinux project which is currently configured to boot into an INITRAMFS by default which is generated within the project; this however has limited rootfs capabilities.
The hardware platform used for this Petalinux project has been imported from the Hardware repository of the same branch as this.
- The Petalinux projects are version-specific. Source files may not be backward compatible and are not automatically forward compatible. Release tags specify the targeted Petalinux version. There is only one version targeted per year, as chosen by Digilent. Non-tagged commits on the master branch are either at the last tagged version or the next targeted version. This is not ideal and might be changed in the future adopting a better flow.
- Eclypse Z7
- Petalinux 2019.1: For installation, please follow the user guide provided by Xilinx Petalinux Reference Guide (UG1144).
This guide will walk you through some basic steps to boot into Linux and rebuild the Petalinux project. After completing it, you should refer to the Petalinux Reference Guide (UG1144) from Xilinx to learn how to do more useful things with the Petalinux toolset. It also assumes that you have managed to install Petalinux 2019.1 as per the Xilinx user guide.
Whenever you want to run any petalinux commands, you will need to first open a new terminal and "source" the Petalinux environment settings:
source /opt/pkg/petalinux/settings.sh
It is recommended to version control your project and rebuild it with the latest features. In order to do that, clone your repository on the appropriate branch:
git clone https://github.com/Digilent/Eclypse-Z7-OS
Run the following commands to build the Petalinux project with the default options:
petalinux-build
petalinux-package --boot --force --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/system_wrapper.bit --u-boot
Once the build is done, you will have format your SD card to FAT and load the <repo-location>/images/linux/BOOT.bin and <repo-location>/images/linux/image.ub on it.
In order to customize the Petalinux project, please refer to the Petalinux Reference Guide (UG1144) which provides all the details regarding the commands which can be used and how to use them in order to achieve this. After each customization, you will have to rebuild the project using the commands provided by the Build the Petalinux Project section of this document.
If you have changed the base hardware of the Vivado design referenced by this project and/or wish to import a new hardware design into this project to build upon, you will need to run:
petalinux-config --get-hw-description=<location-of-your-hdf>
!!!IMPORTANT!!!
Some changes to the hardware will require changes to the device-tree in <repo-location>/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi
