STM32L476RG FreeRTOS multithread issue

[Titus Stalin]

Hi Experts,

I am using STM32L476G MPU, (which sensortile board) and used the following SDK & sensortile BLE example.

~\STSW-STLKT01_V1.3.1\Projects\SensorTile\Applications\BLE_SampleApp

Added FreeRTOS support for multithread in my BLE example.

~\STSW-STLKT01_V1.3.1\Middlewares\Third_Party\FreeRTOS\Source

Here is the code used to run two LED threads.

Code is not running if I enable both threads, but its running if I disable any of thread.

Can you please suggest what to do on this.

Increased the heap/stack size in .ld file and decreased size of stack for thread, but no luck.

static void LED_Thread2(void const *argument)
{
 (void) argument;
 for (;;)
 {
   STLBLE_PRINTF("LED_Thread2 LOOP\r\n");
   osThreadResume(LEDThread1Handle);
   osThreadSuspend(NULL);
 }
}
 
static void LED_Thread1(void const *argument)
{
  (void) argument;
 for (;;)
 {
   STLBLE_PRINTF("LED_Thread1 LOOP\r\n");
   osThreadSuspend(NULL);
   osThreadResume(LEDThread2Handle);
 }
}
 
 /* Thread 1 definition */
 osThreadDef(LED1, LED_Thread1, osPriorityNormal, 0, 32);
 /* Thread 2 definition */
 osThreadDef(LED2, LED_Thread2, osPriorityNormal, 0, 32);
 /* Start thread 1 */
 LEDThread1Handle = osThreadCreate(osThread(LED1), NULL);
 /* Start thread 2 */
 LEDThread2Handle = osThreadCreate(osThread(LED2), NULL);
 /* Start scheduler */
 osKernelStart();
 /* We should never get here as control is now taken by the scheduler */
 for (;;);
