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


Single Step Debugging while a timer is active

Tunisia

Uzair,

context :
supposing you have a project named MyProj under the following folder “~/.../MyFolder/SW4STM32/MyProj/”
within this folder you have a file named “.cproject”

the “.gdbinit” is a file that you have to create if you need to inject some modifications/hooks of normal gdb behaviour (while debugging)

in this case we have created a “.gdbinit” file within the same folder as the “.cproject” with the follwing content (hook) :

define hook-step
mon cortex_m maskisr on
end

define hookpost-step
mon cortex_m maskisr off
end

these hooks disable interrupts before the step and enable them after the step operation
