Freertos semaphore not initialised correctly by CubeMX

[MarcosOrzari]

A new question moved from this post.

I have the opposite issue with STM32CubeIDe v1.18 / MX v6.14.0, I want my semaphore initial state to be depleted, but that is not applied to my code:

  /* creation of DebugUartStringReadySem */
  DebugUartStringReadySemHandle = osSemaphoreNew(1, 1, &DebugUartStringReadySem_attributes);

My .ioc file seems ok:

rtos.0.binarySems.0=allocationType,Dynamic;controlBlockName,NULL;initialState,Depleted;name,DebugUartStringReadySem

Hi Marcos,

Random user here... I'm able to reproduce your error.  I have a starter project for TouchGFX on the STM32U5 using FreeRTOS, so I added two semaphores, one that starts available, one that starts depleted.

Here's the code that CubeMX generated:

void MX_FREERTOS_Init(void) {
  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* USER CODE BEGIN RTOS_MUTEX */
  /* add mutexes, ... */
  /* USER CODE END RTOS_MUTEX */
  /* creation of sem_available */
  sem_availableHandle = osSemaphoreNew(1, 1, &sem_available_attributes);

  /* creation of sem_depleted */
  sem_depletedHandle = osSemaphoreNew(1, 1, &sem_depleted_attributes);

Clearly, that's not correct.  ST, please verify and correct this issue.  (I'm using CubeIDE 1.18.0, CubeMX 6.14.0, STM32Cube FW_U5 v1.7.0.)

Hello @MarcosOrzari 

Thank you for posting!

Could you provide the name of the MCU where you encountered the issue?

KR,

Sure, it's the STM32U585VITx.
