HAL I2S timeout error

[uahma]

HAL I2S timeout error, look at my code below, i had it working one day and now it never works, the HAL_I2S_Receive function is only called once and then I run into HAL_StatusTypeDef being stuck in HAL_TIMEOUT.

while (1)
 
 {
 
   /* USER CODE END WHILE */
 
 /* USER CODE BEGIN 3 */
 
   HAL_StatusTypeDef result = HAL_I2S_Receive(&hi2s1, (uint16_t*)I2S_RX_BUFFER, 24, 100);
 
   HAL_Delay(500);
 
   if(result == HAL_OK){
 
     volatile int32_t data_full = (int32_t) I2S_RX_BUFFER[0] << 16 | I2S_RX_BUFFER[1];
 
     volatile int16_t data_short = (int16_t) I2S_RX_BUFFER[0];
     
 
     volatile uint32_t counter = 2;
 
     while(counter--);
 
     HAL_Delay(500);
 
   }
 
  }

I did make use of __HAL_DBGMCU_UNFREEZE_IWDG() before my HAL_Init(); command but still it does not work. I swear it worked once and i was able to get different sensor data while debugging with GDB server but not anymore and this is driving me crazy.

my code is stuck in result = HAL_TIMEOUT .....
