CCS/CC3200-LAUNCHXL: RTOS-10 Timer Stopped working

Hi,

I have recently upgraded my RTOS from 8 to 10th version.

After couple of print statements , Debugging I found that the Timer has stopped working in my Newly ported code ( My previous code worked seamlessly ), I request you to kindly help me in this process.

Timer I am using

#define TIMER_A 0x000000ff // Timer A

My code where its getting stuck

void mbStartTimerA0( uint32_t usecTimerValue )
{
printText(IN_COM_UART, " @ mbStartTimerA0 ");
printText(IN_COM_UART, "\n");
MAP_TimerDisable(TIMERA0_BASE,TIMER_A);
MAP_TimerLoadSet(TIMERA0_BASE,TIMER_A, MICROSECONDS_TO_TICKS(usecTimerValue));
MAP_TimerIntClear(TIMERA0_BASE, TIMER_TIMA_TIMEOUT);
//// Enable the GPT
MAP_TimerIntEnable( TIMERA0_BASE, TIMER_TIMA_TIMEOUT );
MAP_TimerEnable(TIMERA0_BASE,TIMER_A);
printText(IN_COM_UART, " exiting mbStartTimerA0 ");
printText(IN_COM_UART, "\n");
}

I have found that after the print @ mbStartTimerA0 my code completely stopped ( previous code with RTOS 8 it has printed exiting mbStartTimerA0 and went to further execution as expected )

Hi Shrijith Sharma,

How are you setting the timer handler? This is done with the osi_InterruptRegister. Please take a look at the helper function Timer_IF_IntSetup() found in cc3200-sdk/example/common/timer_if.c which is used by many SDK examples.

I tested and verified the get_time example in the 1.4.0 SDK which uses FreeRTOS 10 and sets up a timer similar to yours. Please try this example and see if the red LED blinks as expected.

Best regards,

Sarah
