Devicetree symbolic link related problem when building "Eco system V2.1.0" distribution

[Machilus]

Hi All

When building "Eco system V2.1.0" distribution of Custom Board based on STM32MP151C chip, there is a problem that devicetree symbolic link is not created.

Symbolic link of custom board devicetree is not created in "tmp-glibc/work-shared/stm32mp1-fiscal/kernel-source/arch/arm/boot/dts" folder.

"TF-A" and "U-Boot" also do not create symbolic link of custom board device tree.

Due to the above, an error occurs because there is no "xxxxxxx.dtb" file when building with the "bitbake st-image-core" command.

Please let me know if there is a way to fix it without manually creating the symbolic link.

Thanks and regards

I solved the above problem.

ENABLE_CUBEMX_DTB ?= "1"

I added the above values to the ".conf" file for custom board configuration.
