thanks for the help so far!

I now have serial debugging working with vmicro.

if i set debugging to hardware, I still get backend not running.

i bought the arduino m0 to allow me to step thru programs for debugging.

will i be ok on the older boards file?

is this something you would help with, if not where should i go for help?

To be honest it is easier to help users in Visual Studio than atmel studio. To use atmel studio we simply hand off to atmel and users are expected to know how its tools work and how to test connection etc. There are also more options in atmel studio therefore unless users explain exactly what they have set we end up guessing.

In Visual Studio it's more within the vMicro menus and we get better errors back from problems launching hardware debug.

just to be sure, vmicro does not do hardware debugging, with stepping etc, correct.

That's not right. From mid last year we released hardware debugging in Visual Studio. You can use either the software/serial debug or the hardware/gdb debug.

You can also run both atmel studio and visual studio on the same machine and try it out.

when I change to hardware debugging, my sketch does not run and i get backend not running.

is there a step by step tutorial for vmicro in atmel studio?

When you switch on use atmel debugging we simply hand over to atmel studio.

I asked you some questions previously but you did not answer them. Here they re again.


Is vMicro>Debugger>Atmel Studio Debugger enabled?
What happens when you click "Debug>Attach to Target"?
What board is shown in the atmel studio project properties? (right click proj name)

It was not before when i got serial debugging going, It was on automatic.
I enabled Atmel Studio debugger now.
I created a new sketch using file/ new /arduino project.  the board was already set to /arduino m0.
for some reason, it wants to assign the ATSAMD18EA to that board.
The board has a 21GA on it so I changed the device to that in the properties.
it does not show a board, device is now  ATSAMD21GA since I changed it.
debug attach to target yields backend not running (no tools)
on the tool tab of project properties, only custom programmer is available

I noticed that there was no tool library path in the tools/options/device & tool libraries/toollibrary path.
i set it to C:\Program Files (x86)\Atmel\Studio\7.0\tools and did debug/attach to target.
it no longer gives backend not running (no tools)
here is the output

Thanks, you do not want atmel to try to build so please open build>configuration manager and uncheck your project from build. We only want the debug side of atmel studio.

You also should not be using the atmel device programming, just normal edbg or serial. What we want is same as arduino ide for upload but with as7 for debug.

the script file exists at
C:\Program Files (x86)\Atmel\Studio\7.0\packs\atmel\SAMD21_DFP\1.3.331\samd21a\gcc\gcc
and can be opened in a text editor

If you right click your project and inspect the atmel studio properties what device is set? 
What device name shows on the tool bar if you see one (I don't mean the visual micro tool bar, atmel has its own tool bar that shows which device it thinks is selected.

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.
