Please se the visual micro debugger to Off or Serial. The "Hardware" option is relatively new, applies only to VS and needs to be hidden from As7. The only option in AS7 is to override the visual micro serial debugger and "use atmel studio debugging".

That might be causing some confusion.


i have it running. breakpoints are working, but i dont see how to step/step into. using the buttons in atmel toolbar results in nothing.  also curious why millis() keeps advancing when the program is halted?

Make sure you are on an upto date version of atmel studio "help>check for updates".

Please show a screen shot of the debug working so we can be sure you are using the atmel debugger and not the visual micro debugger.

If it does not have optimization disabled for the code you are trying to debug it can cause step/break to fail. But becareful with the optimization it can break the build if too much. 

There are ways to disable optimization for chunks of code without disabling it for all related code but it means adding # directives to the code which is messier.

Let's first try debugging only in the .ino file with "no project" optimization. Can you inspect variables and step over simple lines of code, for example adding and subtracting 1 from a variable.

millis() it handled differently by every core. How the debug works is down to atmel and your hardware.

i was running the vmicro debugger.  I switched to the atmel debugger and no project optimization and the screen attached is what I get.

Those are atmel errors so you might get more info by changing the output window from "Micro build" to "Build". The output windows with name that starts "Micro" are visual micro output windows. Atmel has its own.

Try these things in any order.

1) Run a repair on atmel studio via control panel add or remove programs.

2) Create an atmel studio application project and select your board. Click start > debugging to see if it can upload and start the debugger for a standard gcc application.

3) Look at the standard atmel studio project property pages for your project to see which debugger/programmer is selected.

4) Look at tools device programming to see if your device is detected and what config the ide has.

5) Post the verbose micro output when you try to lunch and it fails just so we can see that visual micro isn't doing anything.

1) Run a repair on atmel studio via control panel add or remove programs. THIS IS MY 3RD FULL INSTALL AND I HAVE REPAIRED TWICE.

2) Create an atmel studio application project and select your board. Click start > debugging to see if it can upload and start the debugger for a standard gcc application.  BACKEND NOT RUNNING, NO TOOLS

3) Look at the standard atmel studio project property pages for your project to see which debugger/programmer is selected.  NO PROGRAMMER AVAILABLE, ONLY CUSTOM PROGRAMMER

4) Look at tools device programming to see if your device is detected and what config the ide has.
THERE ARE NO AVAILABLE TOOLS.

5) Post the verbose micro output when you try to lunch and it fails just so we can see that visual micro isn't doing anything.  SEE ATTACHED

There is an update for as7 that allows you to set the micro-controller that the atmel project believes it is using. There isn't a direct connection between the arduino definitions and atmel device names so visual micro has to guess. For SAMD boards Visual Micro is bias to the original Arduino Zero. 

Another AS7 user was using an Adafruit M0 that has a slightly different MCU name. There is a new option on the vMicro>General menu that allows you to switch off Visual Micro attempt to automatically set the Atmel Studio Device. Then you can alter the mcu name to be correct.

Your arduino builds shows the mcu/device name should be SAMD21G18A when your ide is set to SAMD21E18A.

I am running vmicro 1911.23.0
the tools extensions does not show any updates available.

autoselect board/port has been off all along.

when I create a new arduino project using vmicro, It always selects the E version. I change it using the project properties/device to the G18A, which is the device installed on my board.

i closed a solution that I had set up for arduino nano.  created new vmicro new arduino project .  I changed board to pro programming port.  went to change the device, and no samd devices are available.

As I said you should try the version published earlier today to the link I posted in my previous comment.

If that doesn't help then you are really looking at an AS7 issue and I suggested previously testing with a simple atmel gcc project to prove the tools are working.

These issues are why we recommend VS over atmel studio. Unless you already know atmel it is a learning curve for arduino users. In atmel studio we have better control over the hardware debugger than in AS7.

It might be worth re-checking the guide for AS7 here

Thanks, those are all atmel errors not caused by Visual Micro.

ps: I don't think that you haven't said what atmel studio tool(s) you have set in the project properties. If you click click the project name > properties that is a very important area because you are allowing atmel to take control. That is where you would set the programmer/debugger you want to use. That is what atmel is trying to load for debug.

I switched to atmel studio because it seemed like a simpler environment for an arduino type guy.

Would you suggest I try visual studio, which I have previously used instead of atmel?

I think it's an easy thing to think that Atmel is more in tune with micro-controllers and for advanced users who are familiar with the underlying micro controllers it can be. However it is much more complicated for the same reason.

The intellisense can be more robust in atmel studio but other than that Visual Studio is certainly the easiest. It is also easier to support because, for example, if there is hardware debugger problem we have control over the tools to fix it and we can better report the entire build/debug process in our own verbose output.

In your last post atmel studio can not see your board.  EDBG should be in the list, it might be related to my previous note about the wrong process/mcu being assigned to the atmel project.

It is also evident that the last upload you made was with serial debug enabled and NOT using the vmicro>debugger>use atmel studio debugging.
