Importing a Hardware Configuration - 2023.1 English - UG1144

Steps to import hardware configuration are:

1. Change into the directory of your PetaLinux project.

   cd <plnx-proj-root>

2. Import the hardware description with petalinux-config command using the following steps:
   • Using path of the directory containing the .xsa file:

     petalinux-config --get-hw-description <PATH-TO-XSA Directory>

   Or
   • Using the XSA file path as follows:

     When you have multiple XSA files in a specified folder petalinux-config gives you an error. To avoid these kind of errors you can provide complete XSA file path as follows:

     petalinux-config --get-hw-description <PATH-TO-XSA-FILE>

   Note: Changing the XSA file in the <PATH-TO-XSA directory> later gives an INFO: Seems like your hardware design:<PATH-TO-XSA Directory>/system.xsa has changed warning for all subsequent executions of the petalinux-config/petalinux-build commands. This means that your XSA has changed. To use the latest XSA, run petalinux-config --get-hw-description again.
3. This launches the top system configuration menu. When the petalinux-config --get-hw-description command runs for the PetaLinux project, the tool detects the changes in the imported hardware design and launches the menu.

Ensure DTG Settings > (template) MACHINE_NAME is selected and use the option as follows:

• Keep the BSP setting as AUTO when using a Xilinx evaluation board with the default BSP/hardware project. The DTG machine configuration is automatically determined based on the specific design you use.
• For the custom board, keep the default value.
• For customized hardware design implemented on a Xilinx evaluation board, use the values in the following table.

Ensure Subsystem AUTO Hardware Settings is selected, and go into the menu which is similar to the following:

Figure 2. Subsystem AUTO Hardware Settings

The Subsystem AUTO Hardware Settings → menu allows customizing system wide hardware settings. You have a choice to select the processor, memory bank, serial console, flash etc.

This step can take a few minutes to complete because the tool parses the hardware description file for hardware information required to update the device tree, PetaLinux U-Boot configuration files (only for MicroBlaze) and the kernel config files(only for MicroBlaze) based on the “Auto Config Settings --->” and “Subsystem AUTO Hardware Settings --->” settings.
