I am trying to creating u-boot files for self definded project.
Unfortunately i get the error during individual building (see https://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package#Installing_the_OpenSTLinux_BSP_packages:(
Device Tree Source (arch/arm/dts/stm32mp153c-***-mx.dtb) is not correctly specified.
The issue itself is correct. How do i create the *.dtb from STM32 Project (Device Tree Source available for all 4-5 Phases)? In which phase is the generation of this *.dtb File done (Kernel,TF-A,OPTEE,...)?
A dtb file is generated for each boards that you are building and for each software levels.
You have one dtb for your board at TF-A, one at OPTEE level, one at U-Boot and one at Linux level.
The DTB file provides the configurations needed for all the peripherals of your board.
Since you are talking about U-Boot, I recommend you to follow this page that explains how to build the U-Boot from the Developer Package: https://wiki.st.com/stm32mpu/wiki/How_to_cross-compile_with_the_Developer_Package#Modifying_the_U-Boot
