UARTprintf() function doesn't work on Concerto eval board

Hi David,

I'm using both that TMDXDOCKH52C1 - H52C1 and the TMDXCNCDH52C1 - H52C1 ControlCard by itself.

I've tested alot of the demos, the UART demo that I worked with is 'uart_echo_m3' (from the examples in ControlSuite).  It works quite well, here is the setup from uart_echo.c, note the more extensive setup and the use of UARTSend instead of UARTprintf:

int
main(void)
{

    // Disable Protection
    HWREG(SYSCTL_MWRALLOW) =  0xA5A5A5A5;

    // Setup main clock tree for 75MHz - M3 and 150MHz - C28x
    SysCtlClockConfigSet(SYSCTL_SYSDIV_1 | SYSCTL_M3SSDIV_2 | SYSCTL_USE_PLL |
                         (SYSCTL_SPLLIMULT_M & 0x0F));

    // Enable the peripherals used by this example.
    SysCtlPeripheralEnable(SYSCTL_PERIPH_UART0);
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOE);

    // Enable processor interrupts.
    IntMasterEnable();

    // Set GPIO E4 and E5 as UART pins.
    GPIOPinTypeUART(GPIO_PORTE_BASE, GPIO_PIN_4 | GPIO_PIN_5);
    GPIOPinConfigure(GPIO_PE4_U0RX);
    GPIOPinConfigure(GPIO_PE5_U0TX);

    // Configure the UART for 115,200, 8-N-1 operation.
    UARTConfigSetExpClk(UART0_BASE, SysCtlClockGet(SYSTEM_CLOCK_SPEED), 115200,
                        (UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE |
                         UART_CONFIG_PAR_NONE));

    // Enable the UART interrupt.
    IntRegister(INT_UART0, UARTIntHandler);
    IntEnable(INT_UART0);
    UARTIntEnable(UART0_BASE, UART_INT_RX | UART_INT_RT);

    // Prompt for text to be entered.
    UARTSend((unsigned char *)"Enter text: ", 12);

    // Loop forever echoing data through the UART.
    while(1)
    {
    }
}

Hope that helps,

Hi Josh,

Thanks for the advice, however I have tested that exact example myself, with the same code, and it still doesn't work!

I can put a breakpoint on that line and when I go through it, nothing appears on the console.  Just to clarify, should the text appear on the console at the bottom or on the "scripting console" (available through 'view')?

All I have on the Console is:

"Cortex_M3_0: GEL Output: Memory Map Initialization Complete

Cortex_M3_0: GEL Output: Watchdog Timers Enabled

Cortex_M3_0: GEL Output: UARTs Enabled"

Have you changed anything else from that example?

Thanks, Tom

Ahh yes! Thank you so much, it seems so simple but I don't know how I was supposed to work it out myself...? I must have missed a tutorial along the way at some point.

Dera All,

I've the same Concerto based Development's Kit.

I found the same problem with using the UARTprintf() function. I tried to show the output on the serial terminal but UARTprintf doesn't work.

I had good result only with UARTCharPutNonlocking().

Does UARTprintf() function (and in general UART APIs)  need any kind of installation?

Thanks

Andrea

I've never ever ever ever saw this built-in terminal.

Does it exist in CCS 5 ??

Anyway, for anyone looking for a alternative, I've been using the Putty Portable and works flawlessly: http://portableapps.com/apps/internet/putty_portable
