Where to get STM32MP257F-DK source code and device tree file？

[LiamChen]

We are developing the STM32MP257F-DK development board. We searched the development documents on the official website of ST and found the development documents of STM32MP257F-DK (https://wiki.stmicroelectronics.cn/stm32mpu/wiki/STM32MPU_Developer_Package#Installing_the_components_to_develop_software_running_on_Arm_Cortex-A_-28OpenSTLinux_distribution-29). However, there is a sentence "Go on st.com to download the STM32MP2 Developer Package, en.SOURCES-stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06.tar.gz file.". We did not find the source code download entrance of STM32MP2 in the link provided. We further found the source code of the linux kernel in github (https://github.com/STMicroelectronics/linux/tree/v6.6-stm32mp), but did not find the device tree file for the STM32MP2 series. Please let us know how to get the source code of the STM32MP257F-DK so that we can explore it and add our device driver.

Hello @LiamChen ,
The sources are the one provided at this link here:

The device trees are present under Linux sources, at this place: <Linux_sources>/arch/arm64/boot/dts/st

Kind regards,
Erwan.
