Hello All,

I'm trying to access UART3 device on FRDM-K64F, I observed API permissions have no effect on it.

I can open the device successfully using below code, without adding permissions in project.

What does it mean ? anyhow how I can't READ/WRITE to the device with/without API permissions. Any Idea Why I can't read/write on UART3 !?

        int UART_DEVICE_ID = 100; //device id for UART3

        int UART_BAUD_RATE = 9600;

        int UART_DATA_BITS = UARTConfig.DATABITS_8;

        int UART_PARITY_BIT = UARTConfig.PARITY_NONE;

        int UART_STOP_BIT = UARTConfig.STOPBITS_1;

            uart = (UART) DeviceManager.open(UART_DEVICE_ID);

            uart.setBaudRate(UART_BAUD_RATE);

            uart.setDataBits(UART_DATA_BITS);

            uart.setParity(UART_PARITY_BIT);

            uart.setStopBits(UART_STOP_BIT);

            uart.setReceiveTimeout(500);

Thanks,

Ashok
