RTOS/CC2642R: CC2642R GateMutex_enter will cause dead

Would you be able to make a small minimum code example based on one of the examples in the SDK that shows this issue? 

Hi Fan,

What do you mean by "MCU will be dead"? Can you further describe the condition? Have you tried debugging/stepping through and seeing where the program gets stuck or what, if any, error messages you receive?

I would also recommend updating to the latest SDK 3.10.01.11

Thanks,

Alexis

Just as mentioned above, the code is as 

1. define Mutex

GateMutex_Struct SendmutexStruct;

GateMutex_Handle SendmutexHandle;

IArg SendmutexKey;

2. Initiate

GateMutex_construct(&SendmutexStruct, NULL);

SendmutexHandle = GateMutex_handle(&SendmutexStruct);

3. Application

 SendmutexKey = GateMutex_enter(SendmutexHandle[dir]);

critical parameters;

 GateMutex_leave(SendmutexHandle, SendmutexKey);

Debug find that MCU dead, when break debug, it shows

Based on the log it looks like you can have a zero pointer/ undefined variable or similar somewhere in your code that cause the code to access a address outside your wanted memory range. 

The code you have given is not sufficient to determine where the error is since the code uses variables you haven't shown etc. 

Hi TER

MCU was dead when GateMutex_enter() is called, according to error message, PC=0x1002c074, it's in ROM, but not in application.

And this part was totally the same as i used in cc2640R2 in SDK V1.40 which is OK. I don't know what's wrong in the new platform. 

I'm wondering if there's some extra configuration in the new platform.

Also you can run a demo ,adding Mutex, in your Lanchpad to check if it is OK.

Hi M-W,

I've found where the problem is.

There is a definition issue in my Mutex handle initial process, which will cause a invalid handle as you mentioned.

Thanks very much~
