Bootlin is happy to announce a new release of our OpenWrt feed openwrt-feed-st, which provides integration of ST’s STM32MP platforms with the OpenWrt build system. This new release openstlinux-6.1-openwrt-master-mpu-v24.06.26 updates the BSP software components and adds support for the new STM32MP2 platform.
ST BSP Update
The components of the ST BSP were updated as follows:
- U-Boot: v2022.10-stm32mp-r2
- TF-A: v2.8-stm32mp-r2
- OP-TEE: 3.19.0-stm32mp-r2
- Linux: Linux kernel 6.1.109 with OpenWrt patches and patches from ST as of version v6.1-stm32mp-r2
STM32MP2 support
A few months ago STMicroelectronics released its new STM32MP25 processor family. It is composed of ARM64 processors based on single or dual Arm Cortex-A35 cores, combined with one Cortex-M33 and a wide range of peripherals.
A first evaluation board is already available, the STM32MP257F-EV1.
Our feed openwrt-feed-st provides 2 configurations for this 
STM32MP257F-EV1 evaluation board:
STM32MP257F-EV1: minimal configuration for the STM32MP257F-EV1STM32MP257F-EV1-DEMO: more complete configuration for the STM32MP257F-EV1 which mainly includes the OpenWrt Web configuration interface.
The documentation in the openwrt-feed-st feed describes all steps to fetch the OpenWrt code, build it, flash the image and boot the board, with details for both STM32MP1 and STM32MP2 platforms.
