Hi,

I am having the same problem mentioned by another user but I have not been able to solve it.

Everything was working OK until I noticed a message to upgrade Visual Micro today. I ran the upgrade and now my project will not compile. I get the message: 

Compiling debug version of 'LogExp2' for 'Adafruit Feather M0 (Native USB Port)'
     Preprocess: "{runtime.tools.arm-none-eabi-gcc.path}\bin\arm-none-eabi-g++" -mcpu=cortex-m0plus -mthumb -c -g -Os -w -std=gnu++11 -ffunction-sections -fdata-sections -fno-threadsafe-statics -nostdlib --param max-inline-insns-single=500 -fno-rtti -fno-exceptions -w -x c++ -E -CC -DF_CPU=48000000L -DARDUINO=10801 -DARDUINO_SAMD_FEATHER_M0 -DARDUINO_ARCH_SAMD -DARDUINO_SAMD_ZERO -D__SAMD21G18A__ -DUSB_VID=0x239A -DUSB_PID=0x800B -DUSBCON -DUSB_MANUFACTURER="\"Adafruit\"" -DUSB_PRODUCT="\"Feather M0\"" "-I/CMSIS/Include/" "-I/Device/ATMEL/" 3\cores\arduino" 3\variants\arduino_zero" ruit_feather_m0\Debug\LogExp2.cpp" -o "nul"
   Object reference not set to an instance of an object



     An error was encountered during the 'Deep Search' library discovery process.
Debug build failed for project 'LogExp2'

I have tried uninstalling and reinstalling the board support package and Visual Micro itself. I have verified that the files are in their respective folders.

Any help would be much appreciated.

Hopefully this is resolved in 1702.15 sp1 just published.

I am sure that removing the adafruit package from board manager and reinstalling will resolve (use visual micro board manager)

But before doing so please switch on file>preferences>compiler verbose in the arduino ide, then build and email the output as a .txt file to info[at]visualmicro.com

I would like to see which version of board support package is installed and where arduino is finding the tool chain. The verbose output will show this to me.

Thanks

Thanks

I can see that your downloaded hardware has been installed into C:\Users\[your name]\Documents\ArduinoData. (Look at the output from arduino ide that you emailed, it shows ArduinoData is being used)

This is a new location for arduino and might be related to starting of with the windows store version which is also new and causing some support issues. The windows store version doesn't provide permissions for visual micro to see the ide.   visual micro only needs it for help/references and examples so during the next week or so we will release a version that can work with or without the arduino ide.

We will add support for C:\Users\[your name]\Documents\ArduinoData over the next few days then it will work with your configuration.

Alternatively you can remove C:\Users\[your name]\Documents\ArduinoData and then use the visual micro platform explorer > board manager to install the hardware. (Use the Rescan button after hardware has been downloaded and installed or restart the ide)

Visual micro will install the hardware into C:\Users\[your name]\AppData\Local\Arduino15 which is the main place the arduino ide has always used so it will also be happy using the location.

I have to look to see if there other new locations other than ArduinoData so the next release can cater for all.

You also mention in your email that you upgraded to the standard arduino ide from the store version. Can you be clear about the sequence of events. Visual micro would not be looking at the ArduinoData in previous versions unless you have added it as the "contributions path" in tools options, but as a new user I suspect this is not the case.

Version 1702.16 or visual micro is here https://1drv.ms/u/s!AsT00oFsGAmRj8RXjwppn10kZdBOzQ

It supports the ArduinoData folder as an alternative to the standard downloaded hardware locations and should give the same compilation that you are seeing in the arduino ide.

I haven't had a change to try it but it's a simple addition so will hopefully resolve the issues and prevent the confusion.

I fixed it:

1. Removed Visual Micro from VS2015

2. Removed the folders containing Arduino IDE, Arduino Data and packages. The packages were in two places.

3. Downloaded and installed the Arduino IDE windows installer.

4. Added the board packages for SAMD and the Adafruit Feather M0.

5. Verified that the sketch compiles.

6. Installed Visual Micro from the Extensions and Updates windows within Visual Studio.

7. Using the Configuration Manager (which is well hidden) entered the sketch location (in Dropbox this time) and the Adafruit board URL.

8. Opened the Visual Micro Explorer and found that the SAMD and Adafruit packages were already on the list.

9. Opened the sketch in Visual Studio.

10. Selected the Feather M0 board and compiled successfully.

I suspected that my messy installation history was causing the problem.
