VisualGDB windows not working in VS2019

[wtywtykk]

Hi,

I upgraded to vs2019 and VGDB 5.4r9 today. And I found the semihosting window stopped working. When I switch the tab, the window just keep displaying the content of the former tab. It seems that the window wasn’t redrawing itself. Pressing keys  do send the keys to the mcu, but window doesn’t show any change. Other VGDB windows also have this problem.

I’m using openocd and CMSIS-DAP, and the mcu is stm32f401.

There’s a video showing the problem. http://45.77.66.194/20190704-232057957.flv

Thanks!

Hi,

This is actually a bug introduced by the new “Optimize rendering for screens with different pixel densities” setting in VS2019, that prevents the tool windows based on the WinForms technology from being shown correctly. We have added a workaround for this in the following build: VisualGDB-5.4.109.3224.msi

Please let us know if it doesn’t solve the problem.

[ExtSol]

It’s working. Thank you!

Now, when i start debugging i get a following error:

What can i do?

[ExtSol]

but i reinstall VisualGDB-5.4r9-trial everyting is ok, with the starting post problem “When I switch the tab, the window just keep displaying the content of the former tab”

after install the workaround, i get the same error

• This reply was modified 5 years, 4 months ago by ExtSol.

[ExtSol]

My solution for this issue:

I download older version of Visual studio (downgrade to 2017) and VisualGDB-5.4r9-trial debugging feature working fine.

[wtywtykk]

Hi,

The workaround just works fine for me. My environment is: ARM toolchain 7.2.0/8.0.1/r3; STM32BSP 2019.06; OpenOCD 20190625-0.10.0

[ExtSol]

Hi,

Yes, worked for me too, but now, stop working, dont know why 🙁

Versions:

GCC: 7.2.0

GDB: 8.0.1

BSP: 2019.06

OpenOCD: 20190625-0.10.0

Visual Studio: 2017 (15.9.13) / 2019 (16.1.5)

[support]

It’s hard to say what is going on as the log you attached is truncated. Please try using the latest build here: VisualGDB-5.4.110.3225.msi

Then enable diagnostic logs as shown here: http://visualgdb.com/support/logsubmit

Then please attach a screenshot of the error message and the full diagnostic log produced by VisualGDB and we help you get it to work.

[ExtSol]

I following the instructions:

• install: VisualGDB-5.4.110.3225.msi
• started VS 2019 Community
• i do the instructions: http://visualgdb.com/support/logsubmit

The issue is the some.

Here is the screenshot: https://imgur.com/a/t0PQL2w

Here is the source code: https://pastebin.com/shuhrcNK

And i uploaded the log file.

Thanks, this looks like something GUI-related (the actual error is “Invoke/BeginInvoke cannot be called” shown on the screenshot).

Please try using View->Other Windows->VisualGDB Diagnostics Console to narrow this down. I.e. enable debug logging, reproduce the problem and share the diagnostic output from the diagnostic console.

[ExtSol]

Just a moment,

Visual Studio 2017 + VisualGDB-5.4.110.3225.msi are working fine.

only VS 2019 + VisualGDB-5.4.110.3225.msi not working.

I procedure the log which your request and i will try to reinstall VS 2019

I repaired VS 2019 install and work fine. Then create new project, not work again.

Repaired again, and create new project, now works fine… this is a random error… A not have any idea why doing this.

Please analize this issue

[support]

Thanks for the log file. It looks like some combination of settings is preventing VisualGDB from showing some of the tool windows before updating its state.

We have added more diagnostic logging to this build: VisualGDB-5.4.110.3226.msi

Please try reproducing the problem with it and send us the updated log from the VisualGDB Diagnostics Console.
