After LOS\_KernelInit is complete, this sample program will create two tasks that loop the **LOS\_TaskDelay** function and print the log information cyclically.

Drivers can be classified as platform drivers or device drivers. The platform drivers are generally in the SoC, such as the GPIO, I2C, and SPI drivers. The device drivers are typically outside of the SoC, such as the LCD, TP, and WLAN drivers.

The Hardware Driver Foundation \(HDF\) is designed to work across OSs. The HDF driver framework provides strong support for drivers to achieve this goal. During HDF driver development, you are advised to use only the APIs provided by the HDF driver framework. Otherwise, the driver cannot be used across OSs. Before driver development, familiarize yourself with the [HDF](../driver/driver-hdf-overview.md).

LiteOS Cortex-A provides the system initialization process and custom configuration options required for system running. During porting, pay attention to the functions related to hardware configuration in the initialization process.
The LiteOS Cortex-A initialization process consists of five steps:
The LiteOS Cortex-A initialization process consists of seven steps:
1. Add the **target\_config.h** file and compile the macros **DDR\_MEM\_ADDR** and **DDR\_MEM\_SIZE**, which indicate the start address and length of the board memory, respectively. The prelinker script **board.ld.S** creates the linker script **board.ld** based on the two macros.
2. The kernel creates a kernel image based on the linker script **board.ld**.
3. Operations such as initialization of the interrupt vector table and MMU page table are performed in the assembly files: **reset\_vector\_up.S** and **reset\_vector\_mp.S**, from which a single-core CPU and a multi-core CPU start, respectively.
4. The assembly code in **reset\_vector.S** jumps to the **main** function of the C programming language to initialize the hardware clock, software timer, memory, and tasks. This process depends on the feature macro configuration in **target\_config.h** . The **SystemInit** task to be implemented in the board code is then created, and **OsSchedStart\(\)** is enabled for task scheduling.
5. The **DeviceManagerStart** function is called to initialize the HDF driver. This process is implemented by calling the driver configuration file **hdf.hcs** and driver source code in the board code.
2. Define **g\_archMmuInitMapping**, the global array of MMU mappings, to specify the memory segment attributes and the virtual-to-physical address mappings. The memory mapping will be established based on this array during kernel startup.
3. If there are multiple cores, define **struct SmpOps**, the handle to the slave core operation function. The **SmpOps-\>SmpCpuOn** function needs to implement the feature of waking up a slave core. Then, define the **SmpRegFunc** function and call the **LOS\_SmpOpsSet** interface to register the handle. The registration process is completed by starting the framework using **LOS\_MODULE\_INIT\(SmpRegFunc, LOS\_INIT\_LEVEL\_EARLIEST\)**.
4. Create a kernel image based on the linker script **board.ld**.
5. Perform operations such as initialization of the interrupt vector table and MMU page table are performed in the assembly files: **reset\_vector\_up.S** and **reset\_vector\_mp.S**, from which a single-core CPU and a multi-core CPU start, respectively.
6. Enable the assembly code in **reset\_vector.S** to jump to the **main** function of the C programming language to initialize the hardware clock, software timer, memory, and tasks. This process depends on the feature macro configuration in **target\_config.h**. Then, create the **SystemInit** task to be implemented in the board code, with **OsSchedStart\(\)** enabled for task scheduling.
7. Call the **DeviceManagerStart** function to initialize the HDF driver. This process is implemented by calling the driver configuration file **hdf.hcs** and drivers source code in the board code.
Below is the overall initialization process.
The figure below shows the overall initialization process.

It is intended for developers with experience in developing embedded systems. Before following instructions in this document, it is recommended that you familiarize yourself with [OpenHarmony](../../OpenHarmony-Overview.md), including its technical architecture, directory structure, kernel subsystem, and driver subsystem. The following table lists the development boards that have been adapted to the small system.

This document provides guidance for OpenHarmony developers to port third-party libraries that use common compiler organization modes, such as CMakeLists and Makefile. It describes how to set a toolchain in different compiler organization modes and how to add the compiling configuration of a library to the OpenHarmony project. Currently, this guide applies only to Hi3516DV300 and Hi3518EV300.
