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:

System Workbench for STM32


Debugger becomes unresponsive when enabling SysTick interrupt

Hi

If BOOT0 is pulled up the bootloader from ROM gets executed. The debugger then has no source code available. How can it follow the jump to the application?
The appclication can be downloaded to flash memory by st-link v2 hardware connected to SWD without using the build in bootloader. But if the application has not defined a debug interface (SWD or JTAG) you will not be able to do this a second time. Then you have to pull up BOOT0 while reset to reconfigure these pins. I can not imagine why a disabled SysTick allows debugging when starting from build in bootloader.
