Steps to import hardware configuration are:

Change into the directory of your PetaLinux project.
```
$ cd <plnx-proj-root>
```
Import the hardware description with petalinux-config command using the following steps:
1. By giving the path of the directory containing the .xsa file as follows:
```
petalinux-config --get-hw-description <PATH-TO-XSA Directory>
```
2. By giving 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 below
```
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.

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.

Figure 1. System Configuration Menu

Ensure DTG Settings > (template) MACHINE_NAME is selected and change the template to any of the below mentioned possible values.

Note: These values are applicable only to Xilinx® evaluation boards. For custom boards, do not change the configurations.

Note: In our default evaluation BSPs, the configuration is set to AUTO. Based on the design, this DTG machine will be set by Yocto default.

Tip: For details on the PetaLinux project structure, see PetaLinux Project Structure.

CAUTION:

When a PetaLinux project is created on NFS, petalinux-create automatically changes the TMPDIR to /tmp/<projname-timestamp-id>. If /tmp is on NFS, it throws an error. you can change the TMPDIR to local storage while creating the PetaLinux project by running

petalinux-create -t project -s
                              <PATH_TO_PETALINUX_PROJECT_BSP> --tmpdir <TMPDIR
                              PATH>

, or selecting petalinux-config > Yocto-settings > TMPDIR. Do not configure the same location as TMPDIR for two different PetaLinux projects. This can cause build errors. If TMPDIR is at /tmp/.., deleting the project does not work. To delete the project, run petalinux-build -x mrproper.

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.

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.

Note: For more details on the Auto Config Settings menu, see the Auto Config Settings.

The --silentconfig option allows you to reuse a prior configuration. Old configurations have the file name CONFIG.old within the directory containing the specified component for unattended updates.
