Dear forum, right now I am struggling with enabling thread safety for my ARM C/C++ libraries.
Here's the problem I am facing: Actually I am running a multithreaded application on my Cortex-M3 device. I am facing spontaneous crashes and suspect the source of these crashes rooted inside the C or C++ library.
As a solution I am trying to make the libraries thread safe as described here: [1] http://www.keil.com/support/man/docs/armlib/armlib_Chdcgdbh.htm and here: [2] http://www.keil.com/support/man/docs/armlib/armlib_Chdfjddj.htm
Actually I tried to implement [2] by writing extern "C" int _mutex_initialize(int* p_pMutex) { return 1; }
inside my main.cpp file. The problem is that _mutex_initialize is never called. Is there a special switch or anything that I have turn to force the C library calling my _mutex_initialize function?
Many thanks in advance and best regards Jan
