在Visual Studio调试时，UART上的第一个数据丢失了 [英] First data lost on UART at Visual Studio debugging

问题描述

在Visual Studio调试时启动应用程序时，前几个数据丢失。

When start application at Visual Studio debugging, first few data lost.

int main(int argc, char *argv[])
{
    Log_Debug("Application starting.\n");

    // Register a SIGTERM handler for termination requests
    struct sigaction action;
    memset(&action, 0, sizeof(struct sigaction));
    action.sa_handler = TerminationHandler;
    sigaction(SIGTERM, &action, NULL);

	UART_Config config;
	UART_InitConfig(&config);
	config.baudRate = 115200;
	config.flowControl = UART_FlowControl_None;
	int uartFd = UART_Open(MT3620_UART_ISU3, &config);
	assert(uartFd);

    // Main loop
	uint8_t data = 0;
	while (!terminationRequired) {
		while (write(uartFd, &data, 1) != 1) {}
		data++;
    }

    Log_Debug("Application exiting.\n");
    return 0;
}
