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:

Perspective windows keep closing

I am new to OpenSTM32 and Eclipse, so I may be missing the obvious. My problem is as follows:
I am working on some code in the C/C++ perspective window without problem. Once I have compiled and run debug, the application start to behave strange. When I stop debugging and go back to the C/C++ perspective window (click the C icon on the left) and click the mouse in the area I want to continue editing the code, the perspective window closes. Then I open it again, click in the window and it just keeps closing all the time. I’ve found that when I first click on the project in the Project Explorer, the window does not close all the time. Once I’ve clicked there, I can continue to the code editor without the window suddenly closing.

I sometimes see the same behaviour when I have not started debugging. Also, when I have an other application open and return focus to Eclipse by clicking the application title bar for example, the C/C++ perspective window also closes.

And one other thing: when I run the debugger, sometimes the debugger perspective opens, but many times it does not (but it does close the C/C++ window), although I have configured it to always open.

I have installed OpenSTM32 on a second machine, to find out it the problem was caused by my PC, but I’m getting the same strange behaviour on both machines.

Does anyone know what’s going on here and how to fix it?

What do you mean by “The perspective window closes”? There is no perspective window: perspectives are just defining the layout of the Eclipse window (which views/editors are visible and where).

Is this the editor window that closes?
Do you modify the C/C++ perspective layout (opening or moving views)?
How many editor windows are opened?
Which environment are you working in (Windows/Linux/MacOS/X, version, Java version...)
What happens when the “window closes” (another editor opens, the editor pane is empty)?

A few, even low quality, screenshots may help understand your problem; currently nobody can try to reproduce it, or help you correct it..

Hi Bernard, thanks for replying!
I’m not sure why I’ve called this window the “perspective window”. I believe I have seen it called that way but now I’m not sure where. Anyway, I do mean the editor window, or to be more precise, the window that contains the project explorer, the text editor and outline window.
When I first started Eclpse, this window opened as a very tiny window in the upper left corner, but I was able to strech it to fit the main window (right now I would not know how to undo that).

I’ve attached a screenshot of the window layout.

I’m running Windows 8.1, Java version 8, update 101

EDIT: I’m not able to upload an image to this forum as it’s always gives me “upload error 302”. Attaching the image to the post apparently does not work either.



How did you try to attach the screeshot? Did you try using the “Attach file” feature, just below the post editor (just above the “Post”, “Preview”, “Cancel” buttons?)
