    Have you called UART_open()?

    Are you using UART_control(uartHandle, UARTCC26XX_CMD_RX_FIFO_FLUSH, 0)?

    If so, please provide more details on the difficulties you're experiencing.

    Regards,

    The Tx buffer is shifted out according to the baud rate, and the TI-RTOS UART driver contains a timer that expires after a time period that is calculated according to the size of the buffer and the configured baud rate of the UART. You can register a callback for UART writes that will be called when a write has completed being output on the UART.

    There are sets of documents in the TI-RTOS product, in the doc subdirectory. You will find a set of documents for the TI drivers, including UART, within the doc subtree.
