CC2650 adding new task fails when calling stack functions

Hi All,

facing problem with simpleBlePeripheral example with newly created task,

Jumping to error loop when calling stack related function calls from the new task.

in compiler options set following as :

ICALL_MAX_NUM_TASKS=4//cahnged to 4 from 3
ICALL_MAX_NUM_ENTITIES=7 //frm 6
OSAL_MAX_NUM_PROXY_TASKS=3 //<<Added new symbol

Code is:

   #define TEST_TASK_STACK_SIZE 1024//644

   #define TEST_TASK_PRIORITY 1

static ICall_EntityID selfEntity_VT;
static ICall_Semaphore sem_VT;
static Queue_Struct appMsg_VT;
static Queue_Handle appMsgQueue_VT;

void verificationTest_createTask(void)
{
  Task_Params taskParams;

  /* Configure task */
  Task_Params_init(&taskParams);
  taskParams.stack = testTaskStack;
  taskParams.stackSize = TEST_TASK_STACK_SIZE;
  taskParams.priority = TEST_TASK_PRIORITY;

  Task_construct(&testTask, verificationTest_taskFxn, &taskParams, NULL);  
  
}


static void verificationTestTask_init(void)
{
  /* Register the current thread as an ICall dispatcher application
   so that the application can send and receive messages. */
  test = ICall_registerApp(&selfEntity_VT, &sem_VT);

  /* Create an RTOS queue for message from profile to be sent to app. */
  appMsgQueue_VT = Util_constructQueue(&appMsg_VT);  
  
}



void verificationTest_taskFxn(UArg a0, UArg a1)
{ 
   
  verificationTestTask_init();
  
  /* sleeping untill main task get initialised */
  Task_sleep(1000*1000 / Clock_tickPeriod);
  

  
  //-----------

  /* FAILS HERE! JUMP IN TO ERRROR HOOK!  (This exact call works from the defaut application task) */
  osal_snv_write( (osalSnvId_t) DEFAULT_SNV_ID, (osalSnvLen_t) sizeof(NVMDataRamCopy), (void *)&NVMDataRamCopy);

//-----------



}
