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:

debugger issue under windows8

Posted by angelino on 2015-05-20 18:41

Hi to everyone and thank you for that forum.

My configuration

windows 8
usb 3.0 and usb 2.0
stlinkv2
stm32100E-eval with stmicro std_lib

I managed to set up everything thanks to the vrious FAQ and instruction on this website.
The debugger was just perfectly working and from now I can’t launch any debbug anymore.

I removed the stlink driver so let the package installer install its own, the debugger came back but is now off again.


I saw a topic in FAQ about usb 3.0 issues with renesas controller but I have an intel one.
Maybe my problem is trivial but I don’t manage to fix it myself.

Hope anyone could help me fix this.

Thank you for your time and consideration

Hi,

Looking at your screenshot, it seems you started a second debug session while a first one was still active. You should kill it (select the first session and click the red square button, then the grey X button on the right of the Debug tab) then start again to debug your program.

Remember: you can’t start two debug sessions in parallel on the same CPU...

Hi,

I don’t have the same system configuration as you to test but the fact that the debug was working before make me think that maybe :

- The previous debug session is not well terminated, kill the “openocd.exe” process from the Windows task manager if it exists
- The ST-Link/V2 is still busy, unplug then replug it.

Then relaunch the debug session.

If it is still not working, try to connect your the board with “STM32 ST-Link Utility” ? If you can’t, it might be a hardware problem.

Hi,

Thank you for the answers.
Well I tried both your suggestions, but it still doesn’t work.
I just figured out removing and installing stm32workbench makes the debugger works again for a while until, it goes off again.


After killing the openocd.exe, debugger refuse to start over again.I will send other pictures tomorrow.

Killing both stm32workbench and openocd and restarting doesn’t have any effect.
Do you think it will make any change trying to launch stm32workbench in vmware player windows 7 virtual machine as any chance to work ? I am worried about stlinkv2 usb driver on VM.



And yes the board can be connected with STM32 ST-Link Utility, that I actually use to flash the .bin manually on board.
The exactly same setup works perfectly fine on my home windows7 64 bits station with the same board, driver, and stlink probe.
