With that version now both the blink and the dfll program show verification errors.
blink:
Code:
avrdude: verification error, first mismatch at byte 0x0213
0xe7 != 0xe1
dfll:
Code:
avrdude: verification error, first mismatch at byte 0x0212
0xee != 0xe6
Comparing the values in binary
1110 0111 (wanted)
1110 0001 (found)
and
1110 1110 (wanted)
1110 0110 (found)
shows two things:
1. It is always the lower nibble being wrong
2. It is always that 1s are written as 0s:
And
3. It is always around 0x213
I went back to the previous error messages, and it is the same there. Always the lower nibble wrong, always 1s changed to 0s.
Maybe it is time to call it a hardware error, or power supply error or whatnot. However, I should mention that I can program the same xmega on the board with JTAG without problems.
BTW, I still use the original rev 4 bootloader in the at90usb1287 on the board. |

Well I'm thoroughly confused; the transmission system is serial USART, so it's not like a line could be stuck somewhere -- it's either not going to be able to do anything at all, or it's going to work. Lots of others seems to have got it working (myself included) which doesn't leave much else to chance.
Could you please try programming with AVRStudio, and NOT AVRDude? If that still gives verification errors, I'll be both very confused and grumpy as it doesn't leave much else to check. The one thing I can think of is AVRDude not setting the correct erase/page bits in the programming packets, but on my patched AVRDude it seems to work just fine.
When my non-loaner XPLAIN gets here, I'll have to check it on that also.
The bootloader won't have anything to do with the failure to program the XMEGA - something else is afoot.

So i tried it on Windows with Studio 4.18 SP1. Out of ten tries nine worked, one failed at 212. As opposite to Linux where 10/10 fail.
Next week I'll get another Xplain board. I'll try with that one again. |

Hey Dean
Get them to ship an Xplain board also , the Ross can have his back 
Congrats .... You have been "Discovered"

Holy crap! indeed.
(the mercenary in me says "do you really need an AVR One! - how much could you get for it on ebay?"  )
Perhaps you can now confirm the myth that users of the One! have a gentle aura of gold glow around them?

Fantastic!
Finally they noticed your good work, Dean. Maybe you can be the missing link between Atmel and good C-libraries.
I think when you finish your study, they will (and should) offer you a good job.
Congratulations from Germany

Thanks guys!
Do I need it? No. Do I want it? HELL YES! I'll be sure to post a review, etc. when it arrives as I don't think many people have seen one before (I know I haven't) outside Atmel's website.
I'm not certain how Atmel will be using the firmware, but I'm pleased either way. It will be interesting to see if they use it as a base for their own version, or just chuck it on new XPLAIN boards and list me on the XPLAIN page of their website.

Bear in mind that for the cost of an AVR One! they could employ one contract programmer for just 8 hours so if they are actually getting an implied license to use some of your software (which took a whole lot more than 8 hours to write) as a result of this then they are getting a very good deal. OTOH maybe they are just being philanthropic (knowing Atmel I'm guessing the latter). |

Ehm, they already got a LUFA license, like I got one, and like you can get one, too. Not implied, but explicit.

That's right - they can use it, but they must give me credit. I think a company using my firmware over their own for their boards will speak volumes to a potential employer, and I'd like the recognition.
The other (better) possibility is that Atmel pays me the US$1500 license fee I offer to absolve them of this duty, so that they can release binaries without the accompanying author credit requirement.

I am all for you getting $1500.
On the other hand, Atmel has released at least one application notes based on someone else's code. AVR309 (incidentally also about USB) is written by Igor Cesko and describes his software USB implementation, with credit at the end of the document.
I also always had the feeling that the application note describing the Dragon opto-isolation extension is some kind of "student work". I am, however, not sure if the student, intern or whoever is credited in in the note (couldn't find the app. note in a hurry). |

Hey Dean, congrats on the recognition from Atmel (whys the quoted email gone now?). I finally got around to trying out the newest version of your programmer/serial bridge. It seems to work great, I'm sure its gonna be really useful in the future.
One thing I was wondering about though is what it does when it finishes programming. After programming, the Xmega seems to be stuck in reset and I have to unplug the usb to get it going again. With my jtagice mkii it does the same thing when using jtag, but if I use pdi the Xmega resets after I close the programming window. It makes it pretty handy since the Xplain doesnt have a reset button. Any ideas on why your programmer and the jtag does this? Is this the way the avrisp behaves? Any chance you can modify yours so that it behaves similarly to the pdi programming on the jtagice mkii? Have I asked enough questions in a row?
Anyway, thanks a bunch for your work on this! |

The Atmel engineer asked me to remove it as he didn't want all his details and message out in the open. It was dumb of me to simply repost it without first paraphrasing or editing it anyway.

I actually noticed that yesterday morning, and fixed it in the SVN/GIT repositories. If you grab the absolute latest files and recompile, it should release the XMEGA from reset now automatically.
