Hi, I want add two ARM-based boards to the supported boards to OpenBSD in the near future, which I own.
STMicroelectronis STM32MP157F-DK2 board: SoC: STM32MP157F (Dual Core Cortex-A7 with Cortex-M4) Fully (expect the Vivante GPU) documented. U-Boot support: yes STMicroelectronis STM32H747I-DISCO board: SoC: STM32H747 (Cortex-M7 with Cortex-M4) Fully documented. U-Boot support: I'm currently working on it. For the last board, I must create a new ARM architecture: ARMv7-M Any tips where to start? Kind regards, Johannes Krottmayer
