Hi,
im having troubles working with the simulator in a project done with visual micro. Problem is i cant debug code correctly, it seems it doesnt find the source file (just shows disassembly).

Im using Atmes Studio 7, and visual micro.

i followed the guide thats in the build output, that is, i created the .cpp file, i have selected atmel studio deviuce programming, and selected alwasy use programmer for uploading. then i selected the atmel studio debugger from the visual micro debugger menu.

things i tried:
Creating a new normal project. Works OK.
Creating new arduino project from file->new->project. Not working.
Creating a new arduino project from visual micro menu. Not working.
tried disabling the optimizations by using the macros i found somewhere in the web

My project complies fine, its just that it doesnt find the source files when debugging, and im left with only assembler.

i tried searching for more info in the net but i failed to fix the issue.

Am i missing something? Is there a guide, like for dummies, that shows all the steps from start to finish?

Thanks.

Thank you!

at his point im just running an empty project, my .ino file is empty, and my .cpp has just an almost empty loop

I was using an atmega1284p in my previous project, but in this example im using arduino uno board with atmega328p.

If i use "toggle hidden files" i get an error window saying something about some file that already exists with a different extension. It still works though, it shows all the files.

If i use File->Open->"open object file for debugging" i get the same effect, i just see disassembly, no c++ code.

1)
name of elf: test2.elf
folder of elf: i cant find any option to set this, but i think it defaults to the /debug directory inside the project.

2) output files: i can see .elf, .hex, and .o files is there but goes away when debugger starts.
If i look in a working, normal atmel studio project, the .o file does not get deleted. So maybe thats it?


if i see the output of a normal atmel studio project, it has indeed a main.o and also a main.d file

thanks!

Hellooo
i did more testing and discovered the issue.

I installed a new virtual machine, in which i installed atmel studio 6.2 with arduino 1.6.9. Everything worked fine.
Then i installed atmel studio 7, using the same arduino, 1.6.9. Everything worked fine, Huh??
I changed from arduino 1.6.9 to 1.6.12, the same version i have installed here. Issues come back!
I changed from 1.6.12 to 1.8.1. Everything worked fine.
So it seems to be something specific to 1.6.12. 
I checked more versions and came to this list:
1.6.9 good
1.6.10 bad
1.6.11 bad
1.6.12 bad
1.6.13 bad
1.8.1 good

all versions compile fine, but the bad ones wont debug.

I've just had a thought. I might have read some discussion on the arduino dev channel about the debug output compiler switch being switched on. 

I wonder if your findings show that it used to be on then was switched off for a while.

We can compare the verbose compiler output of a single "avr-gcc/++" command to see the difference between compiler switches.

For future reference: Compiler switches can also be added via the visual micro project properties.
