CubeMx generates cmsis-v1 functions when using FATFS+FREERTOS cmsis-v2

Javier1

I am using cubeMX 6.6.1.

When selected FREERTOS cmsis-v2 and FATFS, everytime cubeMX generates code it oveerrides syscall.c with FREERTOS cmsis-v1 prototype funcions.

int ff_cre_syncobj (	/* TRUE:Function succeeded, FALSE:Could not create due to any error */
	BYTE vol,			/* Corresponding logical drive being processed */
	_SYNC_t *sobj		/* Pointer to return the created sync object */
)
{
  int ret;
  
  osSemaphoreDef(SEM);
  //*sobj = osSemaphoreCreate(osSemaphore(SEM), 1);//cubeMX generates this
  *sobj = osSemaphoreNew(1, 1, osSemaphore(SEM));///cmsis-v2 equivalent
  ret = (*sobj != NULL);
  
  return ret;
}
int ff_req_grant (	/* TRUE:Got a grant to access the volume, FALSE:Could not get a grant */
	_SYNC_t sobj	/* Sync object to wait */
)
{
  int ret = 0;
  
  //if(osSemaphoreWait(sobj, _FS_TIMEOUT) == osOK)
  if(osSemaphoreAcquire(sobj, _FS_TIMEOUT) == osOK)
  {
    ret = 1;
  }
  
  return ret;
}

 

is there any way i could prevent cubeMX to override this two functions every time GENERATE CODE is clicked?

is this a cubeMX bug? or is it expected?

Hello @Javier Muñoz​ 

Issue reproduced using cubeMX 6.6.1 , stm32cubeIDE 1.10.1 and Nucleo-F767ZI , I added the two functions that you wrote above in the syscall.c and i clicked "Generate code " again nothing change the functions still there and cubeMX didn't overcome the two functions .

Can you please provide more details about the issue .

Good morning @Javier Muñoz

I recommend you to use stm32cubeide version 1.10.1

It is the latest version and your problem will be resolved 

This is the link to download the latest version that i told you about

I dont think CubeIDE is the problem here, anyway, ill download the latest version and get back to you.

@Ghofrane GSOURI​ I just downloaded the 1.10.1 CUbeIDE

0693W00000SunUJQAZ.png 0693W00000SunVqQAJ.pngAnd as i expected ,the issue is still there, this has nothing to do with the Cube IDE,

Same thing could be detected using a plain text editor.

When generating the boiler plate code wth CUBEMX , when freertosv2 is selected, CUBEMX uses old freertos v1 function definitions in syscall.c causing this error.

the issue is not yet resolved
