Issue Using CubeMX Generated Files on STM32MP135DF with Kirkstone Yocto

Midhul_Pk
Associate II

‎2025-10-23 6:26 AM

Hi all,

I’m working with the STM32MP135DF board and trying to use a fully custom stack including Machine/Device Tree, Kernel, U-Boot, TF-A, and OP-TEE.

Here’s my setup:

  • Poky / Yocto version: kirkstone-4.0.27

  • CubeMX version: openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11

  • Added CubeMX generated files under: 

meta-st/meta-st-stm32-Addons/mx/
└── stm32mp135df-comtrol
    ├── kernel
    │   ├── Makefile
    │   └── stm32mp135f-stm32mp135df-comtrol-mx.dts
    ├── optee-os
    │   ├── conf.mk
    │   └── stm32mp135f-stm32mp135df-comtrol-mx.dts
    ├── tf-a
    │   ├── stm32mp135f-stm32mp135df-comtrol-mx.dts
    │   ├── stm32mp135f-stm32mp135df-comtrol-mx-fw-config.dts
    │   └── stm32mp13-mx.dtsi
    └── u-boot
        ├── Makefile
        ├── stm32mp135f-stm32mp135df-comtrol-mx.dts
        └── stm32mp135f-stm32mp135df-comtrol-mx-u-boot.dtsi

 

  • Generated custom machine by copying stm32mp13-disco-mx.conf.sample.

  • Successfully built the image.

 

Problem:

When I try to flash using the STM32 flashing tool Using Usb, it gets stuck after the 0x03 partition.

I suspect this is due to version mismatch between CubeMX-generated files and my Yocto version.

Questions:

  1. How can I change the Yocto version in CubeMX so it matches my kirkstone-4.0.27 setup?

  2. Am I missing any additional steps when integrating CubeMX generated files into an existing Yocto project?

  3. Are there any known compatibility issues with openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11 files on kirkstone?

Any guidance, best practices, or examples would be highly appreciated.

Thanks!
