What does petalinux do petalinux-build?

Jump to solution

Hi, all!

 

I don't understand that petalinux-build does. Because petalinux-build is binary file, not script.

Petalinux-build uses bitbake command may be.

 

I want to more understand to petalinux.

 use <plnx-proj-root>/build/conf/bblayers.conf?

 

 

Thank you!

Hi @jrceokura

 

In short, petalinux-build internally calls bitbake petalinux-user-image, that generates a device tree DTB file, a first stage bootloader (if selected), U-Boot, the Linux kernel, and a root filesystem image. Finally, it generates the necessary boot images

 

<plnx-proj-root>/build/conf/bblayers.conf?

 

If you want to add any layers to petalinux, then ideally this is the file that you will edit to include the layer
