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:

Can't debug in System workbench for STM32.

Posted by seboli on 2016-11-03 16:36

Hello.

I have made some code for NUCLEO-L053R8 board.
When I try to start debug by pressing the Bug button I get this error message:

An internal error occurred during: “Launching DMATest_Eclipse.elf”.
org.eclipse.cdt.dsf.gdb.service.GdbDebugServicesFactory.(Ljava/lang/String;Lorg/eclipse/debug/core/ILaunchConfiguration;)V

The terminate button is greyed out.

If I try to press Bug button again the software says that Debug DMATest_Eclipse.elf is already running.

Now I have to remove launch.

When I press the green arrow (Run) button I get this message:

The code starts to run but terminate button is greyed out and I can’t open any watch variables.

I use nucleo_l053r8.cfg configuration script.

What is the problem here?

I am greatful for all help I can get.

Regards.

Hello,

The debug error msg is strange, did you choose an AC6 C project at the beggining ?

Did you update the soft with Menu Help => Check For Updates ?

Which system are you using ? Windows or Linux or Mac os ?
Which eclipse version ?

For the “run” session, it is normal you can’t see variables, the debugger is no more connected after it flash the program.
The debug view is not switch automatically since you’re not debugging.
So there is no terminate button too.

Rgds,
Laurent

Hello.

The project is imported from STM32CubeMX.
I have checked for updates a number of times.
The software is running on Windows 10.
I have installed the lates version of AC6. Information regarding Eclipse version I have to back to you tomorrow when I am at my work again.

I am new to OpenOCD.

When you press the Bug button the code shall be executed and the terminate button shall be red, right?
Jumpers on the Nucleo board shall not be changed?

The communication works perfect when I use ST-Link utility software to program the board.So I dont’t think there is anything wrong with the communication link.
I have also closed ST-Link utility to remove USB driver conflicts.

I shall start with checking Eclipse plugins versions tomorrow.

Regards.

Hi, Some USB 3.0 Controllers (such as NEC/Renesas) have a bug that prevents the binary to be downloaded to the board.
Please, may you also check that you are using the latest version of the controller to fix this issue.
Note that sometimes, the device manager seems to be up to date but the issue is fixed after executing the setup provided in the zip.
It can be downloaded from :

Hello Vetch.

Thank you for the solution to my problem.Now it works to debug with OpenOCD in System workbench for STM32. Perfect.

Thank you.
