Introduction

OpenHarmony has organized a Special Interest Group (SIG) SIG_DevBoard to provide support for third-party development boards.

Before 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.

Device Type	Hardware Requirement	Supported Kernel
Mini-system devices	Memory > 128 KB	LiteOS-M
Small-system devices	Memory > 1 MB, with MMU	LiteOS-A and Linux
Standard-system devices	Memory > 128 MB	Linux

Code Preparation

OpenHarmony 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.

repo init -u https://gitcode.com/openharmony-sig/manifest.git -b master -m devboard.xml --no-repo-verify

The download steps for other resources are the same as those in the mainline version.
