Hello everyone,
I am trying to migrate a project for the STM32MP151C from dunfell to kirkstone.
The versions of the main components I am using are the following:
Component | Version |
tf-a-stm32mp | v2.6-stm32mp-r2.2 |
optee-os-stm32mp | v3.16.0-stm32mp-r2.2 |
u-boot-stm32mp | v2021.10-stm32mp-r2.2 |
linux-stm32mp | v5.15.145-stm32mp-r2.2 |
I used a given .ioc file with a newer version of STM32CubeMX (v6.8.0 - openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23) to re-generate the devicetrees and added the custom changes from the old devicetrees (see devicetrees attached).
Eventually during boot following error occurs:

Has somebody an idea why this error occurs and/or how I can fix it?
Any help would be greatly appreciated :)

Hi @dhk112
Before addressing technical point I would first understand/challenge your migration strategy.
What reason to migrate and why only on kirkstone (V4.x) which is close to end of maintenance ?
I would rather recommend to move to latest V5.1 / openstlinux-6.1-yocto-mickledore-mpu-v24.06.26, or even, if you can wait few weeks, the coming V6 ( Scarthgap kernel 6.6 ).
Else your migration strategy looks good, by generating DTS backbone with relevant MX version and porting the custom change.
Maybe a review/comparison against reference device tree generated by CubeMX for our evaluation board may help to catch some hidden policy change that may explain some issues.
Hope it help
