Hello,

I have just installed the latest version of studio 6 beta see herafter.

If I go to the disassembly windows in debug mode, there is no code to be seen, except NOP for all instructions.

What shall I do ?

I have no intention of comparing every component version!

Surely, what you see is what you have built in your project. e.g. the C statements and corresponding disassembly.

Try a trivial project, and report back.

I suspect that you are building something you did not know!

David,

I'm not so sure - there's clearly something going on here. This is the third or fourth thread I've read recently where people are seeing 0xFFFF NOPs where they were expecting to see some disassembled code. So I think something is up. Hopefully the Norway Gnomes are onto the case!

I have given you all the info that might be needed!
The disassembly was working, with the same C statements in previous version!
Debug works ... etc ...;

Pierre,

Atmel will likely want you to .zip up a project that demonstrates this. It would be good (if it's not proprietary) if you could actually post it as an attachment here then we can all load it and try it and see if we see the same effect.

I only installed AS6.2B on this VISTA-32 laptop yesterday (or the day before)

I can see Disassembly in both a GCC and a CV project.
The target is a ATmega328P on a UNO clone board.
The debugger is a Dragon in debugWIRE mode.

I followed all the defaults in the AS6.2B installation.

Yes, the long list of AS6 components is important information. However, I would start from Basics.

e.g. check very carefully that I am building and debuugging the intended project / target.

e.g. if this shows a problem, I would create a new trivial project from scratch.

If this is ok, I would create a new project that duplicates the original problem project.

Yes, of course, most Atmel releases introduce new "features". It helps Atmel and the rest of the community if we can duplicate a problem.

For a start, it helps Atmel to concentrate on a solution. i.e. I am sure that it gets priority in the Bugzilla system.

Having said that, I must confess to building / programming / debugging wrong targets. And I bet that I am not the only one!

David,

Like you, after reading reports of this happening here, I have tried the same experiments and I simply cannot make it misbehave. I think one of the threads that mentioned it said that they are imported an old project and seen this happen but that when they recreated the project using the same source files everything behaved normally. So there's clearly more to it than:

int main(void) {
}

build, debug.

That's why I'd be interested to see a zipped project that demonstrates it - if it travels with the .zip then it's clearly something hidden in the XML or something like that. If it doesn't travel then it's an environmental thing affecting that person's installation alone.

I do hope Atmel are investigating ;-)

I have indeed "imported" an existing project, just launched by clicking on: "my_name.cproj"

But that's wrong - it's the .atsln file you should click on?

(this rings a bell - I think this was mentioned in another thread where the problem had been observed!).

From memory, AS6.1 introduced a very different set of project files to AS6.0 and AS5.
Hence the IDE trying to put new stuff in an AS6.1 or AS6.2 folder.

You often find that the new "Parser" will cope with older format project files. But perhaps not with the more unusual parts.

IAR seem worst for this. At least I have more sense than to ever buy an IAR licence!

Yes, I agree with Cliff. Please post a ZIP so that we can try it for ourselves.

Just for info, the first time I launched Studio 6 beta the debugger refuses to work, claming for a debbug tool which was there (simulator).
I managed to get it working just by launching the ASF wizard. Strange but that's it!

I can see plenty of dissasembly using this project. Could you start by Going to Tools|Options|Tools and enable diagnostic logging? This should be saved in \Atmel\AtmelStudio\6.2\ApplicationStatus.log

I downloade the ZIP file. It would not "open" with Windows. However, I could extract the project folder with 7-Zip.

I "Opened" the .ATSLN file.
I presume that I could have "Opened" the .CPROJ file instead.

The Project built ok with a few Wanings.
I had selected Tool->Simulator but AS6.2 would not start Debugging.

So I changed Tool to Dragon and back to Simulator.

Then it started Debug ok.
I could see the Disassembly window.

Obviously, I have no idea what the program does. So I have made no attempt to "run" it.

Thanks for info
zip file is made with 7Zip since the zip are not allowed in attachment.
Warning are reminder for me, normal!
would not start debugging: As said I had myself to start the ASF wizard to get out of this situation.
I can see the disassembly window: but full of NOP or with the proper code.
I don't have any hardware tool. Can't for Dragon,

Do you start debugging at main() ?
What is the Program Counter value when you flip to Disassembly ?

Quote:

I can see the disassembly window: but full of NOP or with the proper code.

Do you mean "proper C statements" ?

I note that you use |= when disabling JTAG with JTD.
It happens to create 'good enough' instructions.
It seems more foolproof to use =

I often find that my 'Tool' gets disconnected by AS6.
This is generally solved by unplugging and re-plugging the Dragon.

Quite honestly, I can't see why the Simulator would ever disconnect.

I would be terrified of touching anything to do with "ASF Wizard". This laptop is slow enough already!

Perhaps Morten has a better suggestion for forcing a 're-connect' of Simulator.

Clif was asking about parts earlier in the .lss file. You show lines around locations 28ba to 28d6. He was asking about location 23fa.

The locations are given leftmost on assembler lines, before the colon.

The reason Cliff asked specifically for 23fa is that it is the (8-bit) byte address of the (16-bit) word at 11fd.

This, in turn, is the word just after the source annotation

temp2 = HIGH8(sin_low) * HIGH8(sin_low);

from your source file.

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here.

No guarantees, but if we don't report problems they won't get much of a chance to be fixed! Details/discussions at link given just above.

Not really sure what is happening. The logs say that you are launching using AVR8 GDB, which is a bad idea in itself as it doesn't work. However the GUI does not reflect this.

I just did a diff between my openend cproj file and you zipped, and I have a slight difference. Could you try the attached cproj file?

Ok that's it.

It is new from previous version and as I have been the victim can lead to confusion.

I thought he said "simulator"? Can you think of any logical reason on God's green earth that you would ever want the simulator set to "skip programming"?!?! Surely the option should be ignored when the target is the simulator?
