FreeRTOS Semaphore Create Mutex

[fishermr]

I am using the STM32F429i-Eval1 dev kit.  Working on a home appliance that has a LCD touch panel embedded.  I am using trueStudio 9.0 as the IDE.

During gfxInit(), I have traced through the init functions to where gwin_wm.c fun gwinUpdate calls gfxSemInit.  In gfxSemInit the call to xSemaphoreCreateCounting gets stuck when limit=1 and val = 1.  When limit = 0, the functions executes.

Cannot figure out why this is happening.  Probably a setting isn't set correctly. 

Any help is appreciated. 

My project is attached.

Are you initialising freeRTOS correctly?

Good question.  I used STMCube to create the framework of this code.  It seems likely this is the issue.  Investigating,  Thanks

Did you have a look at this? https://wiki.ugfx.io/index.php/FreeRTOS

Also make sure that you're using the latest master branch.

Thanks for the direction.  I read the suggested link many times and changed the code to match this recommendation and still no progress.  I know this issue is related to FreeRTOS.  I have tried using uGFXMain as well. but no change in behavior.    

I have a commercial license and I am good to pay for support.  Would be appreciative if I could get help with this issue  we can get on with the actual development.

Thanks.

I would start by increasing the stack size of your intialization thread: osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 128);

128bytes might not be enough to initialize everything.

Good suggestion thanks
