CM4 compilation in Yocto Layer

[stm32mp1--Player]

Hello,

we have developed a project in STM32CubeIDE which already works.

the the project is generated  "Under Root"  like this:

 

Now we want to implement the compilation in a yocto layer instead of use .elf directly.

we have take into account the extended recipe of example project (recipes/extended/M4projects) and we have adapted it to compile our project. However the .elf files are not same size as the ones generated in CubeIDE and  doesnt work.

is there any solution to implement the compilation of CM4 firmware in yocto ?

thank you
