Can't open Arduino project after manually editing boards.txt

[MystikReasons]

After manually editing the clock frequency of the Arduino UNO from 8MHz to 16MHz I got projects errors while reloading the project. So I closed Visual Studio and reopened it again and now its stuck loading the solution project.

I changed it back to the previous clock frequency but it’s still stuck.

How can I revert this?

I’m using VisualGDB v. 5.5 build 3402.

Update: Every Arduino project is now having errors and won’t build because it has build errors. (see screenshot)

Reloading the project doesn’t solve the issue.

It looks like you broke something in the platform files:

Error reading file (C:\Users\gwerderj\Documents\ArduinoData\packages\arduino\hardware\avr\1.8.1\boards.txt:0): Invalid line format, should be ‘key=value’

The easiest way to fix it would be to just delete the arduino\hardware\avr folder, restart VS, and let VisualGDB download all the necessary packages from scratch.

[MystikReasons]

I did as you said but it just complains about missing the ‘arduino:avr’. It doesn’t download any necessary packages.

Reloading/building the project doesn’t help either.

Please try creating a new project from scratch. Please also update to VisualGDB-5.5.2.3403.msi​. This version will download missing packages when you open the project, given that it was fully loaded before (won’t help for projects that were never loaded with the new build).

[MystikReasons]

You forgot to mention that I have to install the Arduino AVR Boards package in the visualgdb package manager window, I thought it would do it himself.

After reloading the project I’m still having build errors:

Update to your last post: I will try build 3403

Okay so after creating a new project from scratch with the Uno it already has build errors (just created the project).

I’m using your new build 3403.

I also noticed that if you change the hardware directories under Arduino Settings and revert these changes it won’t take the new values.

See my post above: Error reading file (C:\Users\gwerderj\Documents\ArduinoData\packages\arduino\hardware\uni_erlangen\1.8.1\boards.txt:0): Invalid line format, should be ‘key=value’

You see the “uni_erlangen” keyword above but it’s not in the actual hardware directories paths anymore.

Okay so I figured out why it still used uni_erlangen as reference. I thought VisualGDB is using the following path for their packages: …\AppData\Local\Arduino15\packages\arduino\hardware but I found out its using the following path: …\Documents\ArduinoData\packages\arduino\hardware\avr.

After clearing everything what was in it (the uni_erlangen and the avr folder) I restarted Visual Studio and the path was still selected as …\uni_erlangen\…   So this has to be a bug. It still didn’t download the missing package.

So I created a new project and in the device selection it told me to download the avr boards package and this finally installed the package. In the newly created project the build errors disappeared.

And also in every other project the build errors disappeared and the window for the missing packages finally appeared.

Even the projects which wouldn’t open themself anymore are now loading properly.

 

[MystikReasons]

Is the build 3403 missing package feature only for libraries or also for platforms?

That would explain why it didn’t resolve the mssing “Arduino AVR Boards” package on his own.

Would you be able to improve your missing package feature to also locate missing platforms?

PS: The “Resolve Project Load Issues” window is only showing when you have installed the necessary platform files (in my example: the Arduino AVR Boards package).

The new build should report missing platforms as well, however only if they are known to VisualGDB (i.e. listed in one of the platform_index.json files configured via Tools->VisualGDB->Arduino->Package index URLs).
