Build a new project After exporting the hardware description file from vivado, the next step is to create and initialize a new Petalinux project. The petalinux-create tool is used to wear the basic project directory: These parameters are: Import hardware description file 1. Switch to the directory of the hardware description file generated by vivado. E.g 2. Use the petalinux-config - -get-hw-descripTIon command to import the hardware description. Linux Components SelecTIon ---> In the menu, move the cursor to “Subsystem AUTO Hardware Settings - - ->†ENTER to enter the menu. A menu similar to the following will appear: This directory allows customization of system level hardware and software settings. When exiting the system level menu interface, the tool will take a few minutes to complete. The tool will parse the hardware description, update the device tree, and user-configured U-Boot and Linux kernel kernel configuration files. The tool uses your settings in "Auto Config Settings - - - >" and Subsystem AUTO Hardware Settings - - -> to ensure your system is configured to your requirements. For example, if you choose ps_ethernet_0 as the base Ethernet interface, the tool will automatically enable its Linux kernel driver. And if the user chooses to automatically update the U-Boot configuration, it will also update the enable U-boot Ethernet controller. Configuring engineering components If you want to perform advanced Petalinux project configuration similar to enabling Linux kernel options or modifying flash partitions, use the petalinux-config tool with the -c COMPONENT option. 1. Switch to the Pealinux project root directory. 2. Log in to the top-level configuration menu of the system and set the settings you want. 3. Log in to the Linux kernel configuration menu and configure 4. Log in to the root file system configuration menu and configure

Petalinux-create - -type project - -template < CPU_NAME > - -name < PROJECT_NAME>
- -template: The CPUs supported by TYPE are zynqMP, zynq, and mircroblaze.
- -name: The name of the project you will be building.
This tool will create a new Petalinux project directory based on the default template. These parameters will be configured later based on the specific hardware.
$ cd
$ petalinux-config --get-hw-descripTIon -p
The -p option specifies the Petalinux project directory to be initialized or updated with the target hardware description file.
After the initialization is complete, the tool displays the system level menuconfig interface. This automatically displayed interface only appears when the Petalinux project is first initialized. If you want to display this interface later, enter the petalinux-config command in the Petalinux project directory.
