How and where I should I edit stm32mp135f-dk.dts in yocto?? I need to edit pinmux files of kernel, I want that if I make final image files using yocto then those edited images should get include in final image using bitbake? 

Or the second method is to take out developer package and edit pinmux and dtsi, dts files of linux kernel then generate uImage and dtbs then copy them in /boot folder in board.

Please clear my doubts!!!

Hi,

 

We have tried the second method several times and it works perfectly and is definitely faster. If you have any doubts you can always follow the tutorial page:

Before bulding the kernel, adapt your configuration files.
