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 (registration required) various documents highlighting:

Timer Interrupt crashes after changing to c++



One possible cause is that, if your interrupt handler is in a C++ source file, the Interrupt handler must be a C linkage functions. In C++ you must then prepend extern "C" to the function declaration and definition, otherwise the function name will be decorated by the C++ compiler to become something like TIM1_IRQHandler_v instead of TIM1_IrqHandler, thus the linker will pick the default handler which just loops indefinitely...
