Tool/software: TI-RTOS

project : AWS_IOT subscribe_publish_sample

In the time-out interrupt, call osi_MsgQWrite to send back message to main task, and it cause system abort.

The abnormal stack trace is as below:

By the way,I tried the same code in free-rtos,and it runs no problem.

Many thanks.

Hi,

Which version of the AWS SDK are you using? And are you working off of a base example or your own modified code?

Best regards,
Kristen

v2.1.0
1.based on "subscribe_publish_sample" , I register timer interrput

Timer_IF_Init(PRCM_TIMERA1,TIMERA1_BASE,TIMER_CFG_PERIODIC,TIMER_A,0);
Timer_IF_IntSetup(TIMERA1_BASE,TIMER_A,DefaultTimerPeriodicIntHandler);
Timer_IF_Start(TIMERA1_BASE,TIMER_A,1000);

2. And in the function DefaultTimerPeriodicIntHandler, I first clear interrupt as below:
ulInts = MAP_TimerIntStatus(TIMERA1_BASE, true);
MAP_TimerIntClear(TIMERA1_BASE, ulInts);

3. At last, send message back to my main task with api "osi_MsgQWrite," input parameter of time-out is "OSI_NO_WAIT"

Hi,

It looks like you have a blown stack since I see an error being raised in Task_checkStacks. Take a look at this video/presentation. It covers stack management: training.ti.com/debugging-common-application-issues-ti-rtos
