 #### 3.2.2 Copy initialization function 
 
 The function `SystemClock_Config()` is placed in the **board.c** file, which is responsible for initializing the system clock. When using the CubeMX tool to reconfigure the system clock, this function needs to be updated. This function is generated by the CubeMX tool and is placed in the file `board/CubeMX_Config/Src/main.c` by default. However, this file does not include in our project, so we need to copy this function from main.c to the board.c file. In the entire BSP making process, this function is the only function to be copied. The content of this function is as follows: 
 
-![board_1](./figures/board_1.png)
+![board_1](./figures_en/board_1.png)
 
 The relevant parameters of FLASH and RAM are configured in the **board.h** file. What needs to be modified in this file is the parameters controlled by the two macros `STM32_FLASH_SIZE` and `STM32_SRAM_SIZE`. The flash size of the STM32F103C8Tx chip used in the BSP produced this time is 64k, and the size of the ram is 20k, so the file is modified as follows:

 In some series of chips, the chip RAM may be distributed in multiple discrete memory areas. At this time, the location of the heap memory can be in the same continuous memory area as the system memory, or it can be stored in a separate memory area. For example, on the L4 series of chips, the heap memory can be configured in a 96k memory space with a starting address of `0x20000000`, and the 32k memory space starting from `0x10000000` can be used as the system running memory.

 The chip used to make the BSP this time is STM32F103RB, and the FLASH is 128k, so modify the parameters of LR_IROM1 and ER_IROM1 to 0x00020000. The size of RAM is 20k, so modify the parameter of RW_IRAM1 to 0x00005000. Such a modification method is sufficient for general applications. If there are special requirements in the future, you need to modify it as required according to the syntax of the link script.
