1# Development Board Porting 2OpenHarmony has organized a Special Interest Group (SIG) [SIG_DevBoard](https://gitee.com/openharmony/community/blob/master/sig/sig-devboard/sig_devboard.md) to provide support for third-party development boards. 3 4Before learning about how to port the code of a development board, take a look at the device classification on OpenHarmony. The porting methods vary according to the device type. 5 6| Device Type| Hardware Requirement| Supported Kernel| 7|---------|-------------|----------------| 8| Mini-system devices| Memory > 128 KB| LiteOS-M | 9| Small-system devices| Memory > 1 MB, with MMU| LiteOS-A and Linux| 10| Standard-system devices| Memory > 128 MB| Linux | 11 12## Code Preparation 13 14OpenHarmony has created repositories for vendors in openharmony-sig. To participate in the repository development, you need to use the following method to initialize and download the code. 15 16```shell 17repo init -u https://gitee.com/openharmony-sig/manifest.git -b master -m devboard.xml --no-repo-verify 18``` 19 20The download steps for other resources are the same as those in the mainline version. 21 22## Porting Procedure 23 24- [Mini System SoC Porting Guide](porting-minichip.md) 25 - [Porting Preparations](porting-chip-prepare.md) 26 - [Before You Start](oem_transplant_chip_prepare_knows.md) 27 - [Building Adaptation Process](porting-chip-prepare-process.md) 28 - [Kernel Porting](porting-chip-kernel.md) 29 - [Overview](porting-chip-kernel-overview.md) 30 - [Basic Kernel Adaptation](porting-chip-kernel-adjustment.md) 31 - [Kernel Porting Verification](porting-chip-kernel-verify.md) 32 - [Board-Level OS Porting](porting-chip-board.md) 33 - [Overview](porting-chip-board-overview.md) 34 - [Board-Level Driver Adaptation](porting-chip-board-driver.md) 35 - [Implementation of APIs at the HAL](porting-chip-board-hal.md) 36 - [System Modules](porting-chip-board-component.md) 37 - [Third-party Module Adaptation](porting-chip-board-bundle.md) 38 - [XTS](porting-chip-board-xts.md) 39 - [FAQ](porting-chip-faqs.md) 40- [Small System SoC Porting Guide](porting-smallchip.md) 41 - [Porting Preparations](porting-smallchip-prepare.md) 42 - [Before You Start](porting-smallchip-prepare-needs.md) 43 - [Compilation and Building](porting-smallchip-prepare-building.md) 44 - [Kernel Porting](porting-smallchip-kernel.md) 45 - [LiteOS Cortex-A](porting-smallchip-kernel-a.md) 46 - [Linux Kernel](porting-smallchip-kernel-linux.md) 47 - [Driver Porting](porting-smallchip-driver.md) 48 - [Overview](porting-smallchip-driver-overview.md) 49 - [Platform Driver Porting](porting-smallchip-driver-plat.md) 50 - [Device Driver Porting](porting-smallchip-driver-oom.md) 51- [Standard System Porting Guide](standard-system-porting-guide.md) 52 53# Third-Party Library Porting Guide 54 55- [Overview](porting-thirdparty-overview.md) 56- [Porting a Library Built Using CMake](porting-thirdparty-cmake.md) 57- [Porting a Library Built Using Makefile](porting-thirdparty-makefile.md) 58
