Issue with STM32H750 interface development with TI CC3135 wifi module.

[HPosh.1]

I am using cc3135 wireless module to interface with STM32f4 for the application of Mqtt Client. I ported driver library to stm32h750 disco board successfully. But with application copied form TI CC31xx sdk, the stm cube shows some liker errors. If anyone can help to resolve the issue I will appreciate your efforts.

Says you're missing source/libraries with the actual code for pthread_mutex_destroy and sem_destroy

.H include files can define the interfaces, the body code will be in .C files

These functions are part of the pthread library. Try compiling with the -pthread option. Although I wouldn't be surprised if these aren't available on STM32 by default. Perhaps an RTOS is needed by the library which would include these tools.

Thanks for prompt response.

For your reference, I am using STM Cubemx for my firmware architecture and using FreeRTOS as middleware.

Could you please share any direct reference document/link for porting mqtt_client_app to STM32H750.

Honestly, I am using CC31xx wifi module first time. So, required spoon-feeding

I would be overwhelmed, if you can help regarding.

I doubt such a specific document exists.

Solving a problem requires a certain amount of expertise on your end as well. For niche applications, example code is often not available and real programming must take place.
