你好：
我使用的版本信息如下：
Linux：ti-processor-sdk-linux-j7-evm-08_02_00_03-Linux-x86-Install.bin
RTOS：ti-processor-sdk-rtos-j721e-evm-08_02_00_05.tar.gz
因为产品功能，我需要在main domain的MCU2-0上面驱动GPIO0-4 GPIO0-6输出高低电平。
我在rtos\vision_apps\platform\j721e\rtos\common\app_init.c文件的 int32_t appInit()函数里面添加了如下内容：
Board_initCfg boardCfg;
boardCfg = BOARD_INIT_PINMUX_CONFIG |
BOARD_INIT_UART_STDIO;
Board_init(boardCfg);
然后在编译过程中，提示错误如下：

我看了Board_init函数在<ti/board/board.h>头文件里面有声明，rtos\vision_apps\platform\j721e\rtos\common\app_init.c文件里面默认也包含了该头文件，请问我还需要做哪些处理来解决这个错误？
