调网络不抓包，调I2C等时序不上逻辑分析仪，就像电工不用万用表！多用整理的好的文字，比截图更省流量，还能在整理过程中思考。

这家伙很懒，什么也没写！

BSP中定义
static const struct gd32_uart uarts[] = {
    #ifdef RT_USING_USART0
    {
        USART0,                                 // uart peripheral index
        USART0_IRQn,                            // uart iqrn
        RCU_USART0, RCU_GPIOA, RCU_GPIOA,       // periph clock, tx gpio clock, rt gpio clock
        GPIOA, GPIO_PIN_9,                      // tx port, tx pin
        GPIOA, GPIO_PIN_10,                     // rx port, rx pin
        &serial0,
        "uart0",
    },
    #endif
    
    #ifdef RT_USING_USART1
    {
        USART1,                                 // uart peripheral index
        USART1_IRQn,                            // uart iqrn
        RCU_USART1, RCU_GPIOA, RCU_GPIOA,       // periph clock, tx gpio clock, rt gpio clock
        GPIOA, GPIO_PIN_2,                      // tx port, tx pin
        GPIOA, GPIO_PIN_3,                      // rx port, rx pin
        &serial1,
        "uart1",
    },
    #endif

裸机中的定义
#define COMn                             2U

#define EVAL_COM1                        USART0
#define EVAL_COM1_CLK                    RCU_USART0
#define EVAL_COM1_TX_PIN                 GPIO_PIN_9
#define EVAL_COM1_RX_PIN                 GPIO_PIN_10
#define EVAL_COM1_GPIO_PORT              GPIOA
#define EVAL_COM1_GPIO_CLK               RCU_GPIOA

#define EVAL_COM2                        USART1
#define EVAL_COM2_CLK                    RCU_USART1
#define EVAL_COM2_TX_PIN                 GPIO_PIN_2
#define EVAL_COM2_RX_PIN                 GPIO_PIN_3
#define EVAL_COM2_GPIO_PORT              GPIOA
#define EVAL_COM2_GPIO_CLK               RCU_GPIOA

看着是一致的

问题已解决，解决方案是找GD厂家要了RTT的demo，谢谢大家关心，国产的操作系统和国产的芯片按理理应该配合的更好一点，国产想说爱你不容易啊！ 在调不通就准备换smt32了
