Hello,
I have a small problem, the Xplain working (as AVRISP-MKII) with WinXP just fine! But in Windows 7 (32-bit) does not work, there is the following error:
avrdude -p atxmega128a1 -P usb -c avrispv2 -U flash:w:test4.hex
avrdude: stk500v2_recv_mk2: error in USB receive
avrdude: stk500v2_recv_mk2: error in USB receive
or with -B 10
avrdude -p atxmega128a1 -P usb -c avrispv2 -B 10 -U flash:w:test4.hex
avrdude: stk500v2_recv_mk2: error in USB receive
avrdude: stk500v2_recv_mk2: error in USB receive
the original AVRISP-MKII is working fine!
Greetings |

For everyone: I'm now posting builds of the firmware on my site - http://www.fourwalledcubicle.com/XPLAIN.php - for those who do not want to compile it themselves. The build on my site is currently for AVRStudio only (not avrdude) but I'll start uploading avrdude ones from this week forward also.
The latest firmware revisions are MUCH, MUCH more reliable when in serial bridge mode -- lost characters are now the exception rather than the rule, and the baud rate is configurable in the user's terminal.
dandumit: For AVRDude on Windows you need to recompile with the libUSB compat compile time option.

I built a LUFA based XMEGA programmer with AT90USB1287 and it works fine. There are some questions:
1- As I use IAR for C programming (and not gcc), the first question is about changing َAT90US1287 to other part numbers. Is it sufficient to change MCU = at90usb1287 to MCU=at90usb646(or other parts) in makefile and then recompile in AVR Studio?
2- Can AT90USB82 be used for this programmer?
3- There is an automatic update feature in Atmel AVRISPMKII for new versions of AVR Studio. Is this feature present in LUFA based MKII? |

Yes, the makefile will control everything you need, as all my source code for the project adjusts as needed to suit. This also applies for the other makefile settings - just make your changes, and recompile with a "make clean" followed by a "make all".

2- Can AT90USB82 be used for this programmer?
Technically yes, with reduced functionality. Due to the limited space available you will need to either disable ISP functionality, or disable PDI/TPI functionality via the makefile. Future revisions may be able to fit into the 8K of the AT90USB82 without this restriction.

3- There is an automatic update feature in Atmel AVRISPMKII for new versions of AVR Studio. Is this feature present in LUFA based MKII?
No, as AVRStudio believes the USB AVR to be a real AVRISP-MKII, thus even if it was possible to do so it would be disastrous. You will need to update manually with each (roughly 2 month interval) LUFA release, or as needed from the SVN.

Thanks Dean.
Also I saw a new difference in reading VTarget(in HW Settings window). This voltage is zero for LUFA based programmer and 3.3v for Atmel MKII. |

The ADC channel used to detect VTARGET is configured in the makefile - it default to ADC channel 2. Connect ADC2 of your AVR to your target's VCC to detect the target programming level. Note that if your board is running off a lower voltage than the target board, you'll need to add in a resistive divider and set the scale factor in the makefile accordingly.
On the USB AVRs without an inbuilt ADC, the VTARGET value will be reported as 5V at all times.

How can ISP functionality be disabled via the makefile for using َAT90USB82 as a PDI programmer? |

Just change the line:
Code:
LUFA_OPTS += -D ENABLE_ISP_PROTOCOL
To:
Code:
#LUFA_OPTS += -D ENABLE_ISP_PROTOCOL
In the makefile and recompile.

| I have some reports from LUFA based mkii users about corruption of at90usb162 firmware, after a few microcontroller programming. The problem is solved by reprogramming of at90usb162 (by FLIP). What can be the reason for this problem? |

How do you know firmware is corrupted?
Because by roprogramming the at90usb, programmer returns to normal operation. |

Hmmm. I can't think of any reasonable way that the firmware in the programmer itself could be coming corrupt, unless the bootloader's reprogramming routines were firing somehow. Do you have a procedure to replicate the issue?
Does the programmer become completely unresponsive, or does it just fail to connect to a target properly?

I asked the programmer owner and he told about a "connection fail" (or "fail connection"?) message from AVRStudio. |

@Dean ...
Could one (easily) "Trick" an UNO into acting as a ISPMKII ?
I mean the M8-USB chip could signal the correct vid/pid & act as a serial gw to the m328 , doing the programming ...

Hello...
Will this AVRISP-MKII works on xmega-a1 xplained (ie.32uc3b1256)? |

yes, LUFA already comes with a pre-configured project for the XPLAIN |

| That XPLAIN uses at90usb1287, I'm talking about XPLAIN with 32uc3b1256 as its usb controller. |

As of early this week LUFA can now run on the AVR32 UC3A0, UC3A1, UC3A3, UC3A4, UC3B0 and UC3B1 series microcontrollers, but I've still got a lot of porting work left to do - specifically, I need to fix up the bajillion endianness assumptions I've made when working with serialized structs, and I need to add the correct packing attribute where it is needed.
That means my firmware does not currently run on the new XPLAIN-A1 board, but it's not too far off.

Hmm, I can't see how that could affect the firmware - if the programming window pops up, then the firmware is alive enough to perform USB and V2 protocol processing duties, so it can't be too dead. Reloading the firmware via an external programmer would reset the EEPROM and thus the reset line polarity parameter, but that's not done when reprogramming through FLIP.
- Dean
EDIT: Hmm, that begs the question, where's the AVR32 UC3A2? |

Thanks for the light, can't wait to see it running on the new xplain-a1  |
