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:

openOCD with GDB: how to ignore interrupt and how to make openOCD FreeRTOS aware?


In my application, I am using FreeRTOS underlying CMSIS-RTOS API. I am facing two issues related to RTOS and interrupts while debugging. whenever I start debuggig my application, debugger alaway go to interrupt hence I can not step in or step over other functions. I want to some how mask interrupt before step in and after stepping in, interrupt should be unmasked so that my application works properly. I read some post where it suggested to give a command

  cortex_m maskisr auto 

from openOCD DocumentationQuestion

but it gives me error while debudding.

 Error in final launch sequence
Failed to execute MI command:
cortex_m maskisr auto
Error message from debugger back end:
Undefined command: "cortex_m". 

I have written this command in Debug Configuration > Startups > Run Commands dialog box.

The second issue is, I want to make openOCD FreeRTOS aware. I have followed a blogpostQuestion and made a change in the script stm32f7xx.cfg. (this script is at location “C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.debug_2.4.0.201902141520\resources\openocd\st_scripts\target”). So, I wrote in that script.

 $_TARGETNAME -rtos auto configure -work-area-phys 0x20000000 -work-area-size $_WORKAREASIZE -work-area-backup 0  

But I am getting an error

 Error: invalid subcommand "-rtos auto configure -work-area-phys 0x20000000 -work-area-size 0x8000 -work-area-backup 0"

can anyone please tell me how to resolve these issues?

I am using:

openOCD(for 32bits Windows) version: 1.22.0.xxx
