# Mini-System Devices with Screens – Bestechnic SoC Porting Case
This document exemplifies the porting procedure for a development board on a mini-system device with a screen – an intelligent switch panel. It uses the BES multi-modal V200Z-R development board powered by the Bestechnic BES2600W SoC as an example. Components such as `ace_engine_lite`, `graphic_ui`, `aafwk_lite`, `appexecfwk_lite`, and `HDF` are adapted based on the OpenHarmony LiteOS-M kernel. This example uses the board-SoC separation solution as the porting architecture, the Newlib C or Musl C library as the toolchain, and GN and Kconfig graphical configuration for LiteOS-M kernel compilation.

This document describes how to port small development boards with screens based on the [BearPi-HM Micro development board](https://gitee.com/openharmony/device_board_bearpi) of the `STM32MP157` SoC from STMicroelectronics, so as to adapt components such as `ace_engine_lite`, `graphic_ui`, `aafwk_lite`, `appexecfwk_lite`, and `HDF` to the `OpenHarmony LiteOS-A` kernel. The porting architecture uses the solution where `Board` and `SoC` are separated.
