Building PetaLinux

The PetaLinux build process entails the following tasks.

• Build the Linux Kernel
• Build GNU tools
• Build the Root Filesystem
• Build the U-Boot bootloader

Build Procedure

Change into the $PETALINUX/software/petalinux-dist directory.

$ cd $PETALINUX/software/petalinux-dist

Execute the following command to start the build process.

$ yes "" | make oldconfig dep all

This step will take a while to complete. During the build process the build message will be printed on the console. If any error occurs, rectify the error and repeat this process.

Output Images

Once the build process is completed, all the images are located in both the $PETALINUX/software/petalinux-dist/images and the /tftpboot directory.

The following table describes the output images from this build process.
