Adafruit nRF52840 cannot build

I have been trying to move my development on an Adafruit Feather nRF52840 over to Visual Studio and Visual Micro.

I am unable to get anything to successfully compile - using the Blink example as a starting point.

I have unselected and reselected the board in board manager and received the errors in the attached jpg.
It appears that the extraction of the necessary files won't work.
I have tried running VS as admin and get the same error.

Looks like some sort of permissions issue but strange it fails as admin.

Try installing the package via the arduino ide board manager. We use the same system so that should be automatically detected the next time you run vs or click rescan.

thanks - Vmicro picked up the board once installed via Arduino, thank you.

I am still unable to build anything for the nRF52840, unfortunately. I have attached the build output.

Examples for the more basic Arduino boards such as Uno build just fine.
Thanks for your help.

It can't find the toolchain which is why we see unresolved {variables} in the build output. This variable {runtime.tools.arm-none-eabi-gcc.path} should contain the path to the adafruit tool.

I suggest you open board manager and remove then re-add the adafruit toolchain so that it is unpacked onto your pc again.

I've done this a couple of times already. I can only install the board via Arduino as discussed above.

Oh I see sorry, I suspect that is virus checker preventing the creation of tools or permissions but you said you tried as admin. 

Do you have a folder called appdata\local\arduino15\packages\adafruit\arm-no...

Ah...ok. it is becoming clearer now.
I spoke to our corporate IT dept. The IT security model prevents exe files (and maybe some others) from running within %appdata% or its subfolders, even when logged in as admin.
They suggested that I try to change where the activity happens, into a different folder which is outside %appdata%.

I don't have that specific folder. I have:

C:\Users\Robin.Shaw\AppData\Local\Arduino15\packages\adafruit

which contains only \hardware and \tools

Ok, if you move the Arduino15 to below a folder called Portable below the arduino ide then both arduino and visual micro will use that instead. You will need to create the portable folder.

Alternatively in the tools>options>visual micro there is a "Contributions" path that you can set. Then our Board Manager will work in that path for the \packages.

Actually I have just checked, and found this:
-gcc\7-2017q4\share\doc\gcc-arm-none-eabi

Hi, I moved the Arduino15 folder to 

C:\Program Files (x86)\Arduino\Portable\Arduino15

as suggested. I still can't get it to work. See attached log file.

I also tried changing the Contributions path as suggested. 
I tried C:\Users\Robin.Shaw\AppData\Local\Arduino15
and C:\Users\Robin.Shaw\AppData\Local\Arduino15\packages

Still no joy.
Is there anything else that I can try, or should I give up?

Actually it's worse than I thought. Creating the Portable folder seems to have broken the ability to download board packages within the Arduino environment:

Error downloading https://downloads.arduino.cc/package_index.json

The use of the portable folder is a system designed and published by arduino.cc. Please use the arduino.cc forum to get that working for you.

Visual Micro is working correctly, it seems that all the issues are related to permissions so I can't be of much help except to say that you can expand the zips yourself into the packages folder. Installing packages is simply a matter of downloading them into the staging folder then unpacking them.

Might be worth letting your IT dept know that java still appears to be able to create and run .exe in appdata. It's only native windows programs that can not. Seems like half a job Smiley
