}
int main(void)

uint32_t byteCountBuff;
hardware_init();
NVIC_SetPriorityGrouping(4);
GPIO_DRV_ClearPinOutput(kGpioLED1); //测试用例
GPIO_DRV_SetPinOutput(kGpioLED1); //测试用例
GPIO_DRV_ClearPinOutput(kGpioLED2); //测试用例
GPIO_DRV_SetPinOutput(kGpioLED2);//测试用例
UART1_INI();
while（1）
{
UART_DRV_EdmaReceiveData(1,buffStart,byteCountBuff);
UART_DRV_EdmaSendData(1, buffStart, byteCountBuff);
}
}
如果把UART1_INI中的内容移植到main里面程序运行OK，但是放到UART1_INI中运行就不正常。
