 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.  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.
