BIOS, Semaphore

Hi Jayendra,

I will move your thread to TI-RTOS (BIOS) forum to get the appropriate response.

Thank you.

Thanks Rajasekaran .

Hi Jayendra,

What board (core) are you running the app on ? Also, how are you tracking the memory usage ?

Hi Ashish,

I am Running on core 0  of  EVM 6618.

For tracking memory usage i am viewing "HeapMem in  ROV".

Thanks For your Reply Ashish.

Hi Jayendra,

When the semaphore is deleted the memory (0x20 bytes) should get released and the HeapMem free size should increase by 0x20.

Hi Ashish,

The problem is it is not happening. It is not releasing memory (0x20 bytes).

To create Semaphore i am using :

 hResultSem  =   (void*) Fftc_osalCreateSem ();

To delete it i am using

Fftc_osalDeleteSem(hResultSem)

Please verify it if you have the code for  creating and deleting the semaphore.

 Best Regards,

Jayendra

Hi Jayendra,

Have you tried stepping into Fftc_isalCreateSem() & Fftc_osalDeleteSem() wrappers ? Can you confirm they internally call Semaphore_create()  & Semaphore_delete() ?

Please share the fft library version you are using so I can take a look.

Ashish

Hi Ashish,

Thanks for your reply.

I have taken demo project from pdk_6670_1_0_0_21.

I could not step through those call as they were #define in fftc_osal.h.

/* Map out all FFTC Semaphore APIs to corresponding BIOS implementations */
#define Fftc_osalCreateSem() (Void *) Semaphore_create (0, NULL, NULL)
#define Fftc_osalDeleteSem(X) Semaphore_delete (X)
#define Fftc_osalPendSem(X) Semaphore_pend (X, BIOS_WAIT_FOREVER)
#define Fftc_osalPostSem(X) Semaphore_post (X)

The bad thing is in each fftc call there is leakage of 0x20 Bytes.

Please just see the demo fftc project and you will find it. For reference semaphore is created in Fftc_rxOpen() function and is deleted in Fftc_rxClose() function.

Hi Jayendra,

I was able to install pdk_C6670_1_1_2_6 (could not get the version you have). Can you provide the exact example project name ?

Best,

Ashish

Hi Ashish,

You can run FFTC _Simple_test Project . I worked on single core.

I the file name testsinglecore.c you will find athe below mentioned function in which Semaphore is created.

((hRxObj = Fftc_rxOpen (hFFTC, &rxCfg)) == NULL)

In the same file testsinglecore.c  you will find the below mentioned function which deletes the semaphore.

Fftc_rxClose (hRxObj);

Best Regards,

Jayendra
