STM32MP153 custom layer No rule to make target

[JMD]

Hello, 

If I put my new machine conf and device tree in meta-st-stm32mp-addons I can compile device tree and my image without any error. 

But if I use my own layer meta-my-layer (in meta-st), machine config is used but I have this message : | make[2]: *** No rule to make target 'arch/arm/boot/dts/st/stm32mp153c-linux-platform-mx.dtb'. Stop.

I read the forum and documentation but, I don't find a way to have a working project. 

Could you explain me how to create my own layer to be outside meta-st-stm32mp-addons  (to use my own git) and compile my new machine with associated device tree ?

Thank you so much for your help

Hello @JMD ,
Is it possible for you to provide a kind of tree of your Yocto layer here (with folders, subfolders) to check the architecture of your Yocto layer ? 

If sensitive information are inside, maybe you can filter or replace by a tag the sensitive file names / information.

I guess you are already aware about this article:

• https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package
• https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine

Did you take the same architecture than the addons layer ? Are you able to source your own MACHINE ? Do you well have your Yocto layer inside the Yocto BUILD path ?

Kind regards,
Erwan.

Hello,

My bad, I read lot of time these documentation but I forgot to add meta-st-stm32mp-addons into NEEDED_BSPLAYERS

#@NEEDED_BSPLAYERS: layers/meta-openembedded/meta-oe layers/meta-openembedded/meta-python layers/meta-st/meta-st-stm32mp-addons

 It works fine now. 

Thank you and sorry for inconvenience.

Best regards,
