SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32


Problem with "undefined reference to"

France

Hi David,

The problem here is that the math_helper.c file is a C program and your main.cpp is obviously a C++ program. You must slightly modify the math_helper.h file so that it declares its functions correctly to be called from C++: You should add, just after line 47 in math_helper.h:
#ifdef __cplusplus
extern "C" {
#endif
and just before the final #endif
#ifdef __cplusplus
}
#endif

so that your functions are properly declared as C functions when math_helper.h is included in main.cpp.

Hope this helps,

Bernard (Ac6)
