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:

Many thanks to Peter Shook for his hint with startup option.

Alternative way is to fetch this address from output.map file. Search for line “Reset_Hanlder” and you’ll find 

 .text.Reset_Handler
                0x000000000800d5d0       0x50 startup/startup_stm32f103xb.o
                0x000000000800d5d0                Reset_Handler


Here 0800d5d0 is the PC value you’ll need.
Moreover, in my case, these addresses differed by 1 (which is very strange), and only the value from output.map worked, whereas the first one did not.
