RTOS/SIMPLELINK-CC13X2-26X2-SDK: Using two UARTs in two tasks

Yue,

Could you provide us with some code snippets on what you are doing? There should be no direct problems in doing what you say you are doing.

Sorry for my delayed reply, unfortunately, i cannot share the code - i don't work for FBI, not a spy neither. just company policy. but i create a 'clean' version. the following code worked...but if i just create another task, and move ' funcUsedUart1 ();'to another task, after starting up
' retval = funcUsedUart0 ();' stopped...

Void
taskFxn (UArg a0, UArg a1)
{
int32_t retval = 0;

/* Run config file and calibration function. */
retval = funcUsedUart0 ();

if (retval != 0)
{
System_printf ("App not starting...\r\n");
for (;;)

Task_yield ();
}
}

/* Kick off application - Forever loop */
while (1)
{
funcUsedUart1 ();
}
}

Void main ()
{
Task_Params taskParams;
... ...
UART_init ();
UART_Params_init (&uartParams);.
uartParams.baudRate = 9600;

uartParams.readTimeout
= UART_READ_TIMEOUT_SECONDS
* (MICROSECONDS_PER_SECOND / CLOCK_TICK_PERIOD);

uartParams.readEcho = UART_ECHO_OFF;

uartCfg = UART_open (Board_UART0, &uartParams);
if (uartCfg == NULL)
{
while (1)
{
;
}
}
UartPrintf_init (uartCfg);

UART_Params_init (&uartParams_1);

uartParams_1.readTimeout =
UART_1_READ_TIMEOUT_SECONDS
* (MICROSECONDS_PER_SECOND / CLOCK_TICK_PERIOD);

uartParams_1.baudRate = 9600;
uartCfg_1 = UART_open (Board_UART1, &uartParams_1);

/* Configure task. */
Task_Params_init (&taskParams);
taskParams.stack = myTaskStack;
taskParams.stackSize = APP_TASK_STACK_SIZE;
taskParams.priority = 1;
Task_construct (&myTask, taskFxn, &taskParams, NULL);

BIOS_start (); /* enable interrupts and start SYS/BIOS */
}

make sense! i will try that and let you know. this leads to another question, can i do the UART initialization in the task instead in the main()?
