Freaks,

I've just completed what appears to be a working first revision of a programming firmware for the XPLAIN board, loadable via FLIP into the onboard AT90USB1287. When loaded, it will cause the USB AVR to enumerate as a AVRISP-MKII which (with the latest AVRStudio release) can then program the board's XMEGA via its PDI interface.

I've attached the first build of the programmer firmware here. All those with XPLAIN boards gathering dust because you don't have an external programmer - this is for you! All I ask is for some feedback; post here if the firmware works (or doesn't work) for you.

For those interested in a generic open source XMEGA programmer, the source code for this is located in my LUFA project public SVN at http://code.google.com/p/lufa-lib/, under the Projects/AVRISP/ folder.

A very, very, very big special thanks to Justin Mattair for his help with the PDI protocol, and to Ross McKenzie for loaning me his XPLAIN board for development.

Note that Rev 1 XPLAIN boards have a faulty bootloader in the USB AVR, and cannot be flashed with this firmware without an external JTAG programmer.

EDIT: Latest build and source is now available from my site: http://www.fourwalledcubicle.com/XPLAIN.php

EDIT: I've posted a short guide to loading and using the firmware on my blog: http://fourwalledcubicle.com/blog/archives/508

If they offered you a job in Finland, would you move up there?

What should he do in Finland? Lurking over the border into north Norway, around the corner and around Sweden, to figure out what the Atmel guys are doing at almost the other end of Norway?

So do we still keep the bridge functionality?
How do we switch from programmer to bridge?
If you haven't fininshed a full manual, why not? Wink

Nice Dean.

Does one have to check out via SVN 0r is there an uptodate Zip

Well i used SVN Smile

Is there a special "Board ID" for the Xplain board in the makefile ?

Reading just the first 256 bytes of the flash takes, however, 25 seconds. 25 s / 256 bytes ~= 100 ms/byte

I didn't try programming.

Every time I hear "Finland", I always think of that Monty Python song. If Atmel were ever to offer me a job, I think the bits wouldn't have time to travel to my inbox before I would already be on a plane over there.

Programmer only for now. Once it's shown to work, I'll make a special dual version which can act as a programmer or a bridge, depending on a jumper (or similar switching method). I'd be able to do both at the same time, except the Atmel drivers won't bind to a compound device.

Yes, SVN only for now, until the next release (which will be as soon as I can confirm this working for the unwashed masses). When compling, specify "BOARD = XPLAIN" in the makefile and it'll do the rest to ensure it will work on the board.

That's ridiculous - something's wrong there with how AVRDude is sending the bytes; I'll go check it out. Under AVRStudio, my code is currently faster than the Atmel JTAG, by virtue of it's 1MHz bus since it's located so close to the target chip physically. Writing the QTouch app takes less than a second, and full 256KB readback takes only 5 seconds or so. I'll go see what's what.

ArnoldB, where did you get your AVRDude build (and patch), and what OS are you using? The latest AVRDude in WinAVR doesn't work under Windows for me, as it doesn't want to work with the USB port. Under Ubuntu, I get a faulty (0x00) readback on almost every read. Since yours apparently works (and since the code works with AVRStudio), I'm thinking I need to get a later avrdude version.

Yep, AVRDude's jiggered - no idea how you got yours working ArnoldB. I compiled from the latest source and ran some tests - AVRDude is trying to read the wrong addresses (it reads address 0x02000090UL for the signature, instead of 0x01000090UL, for example). If I force it to continue, I see the same crazily slow read speed you do when reading out normal bytes.

I think I might see if I can figure out the avrdude code, and make my own patch.

EDIT: Darn. After fixing it myself in the source, I then through to seek out ArnoldB's mentioned patch, and found it at http://www.avrfreaks.net/index.php?name ... ;p=645370. Using that and the slightly updated version attached here, it all works great now.

EDIT 2: Removed updated build - see original post for latest version.

The first revision of the Xplain board was a composite device with a dual CDC class so both programmer and serial interface was available at the same time.

This can be achieved by using the association descriptors in the USB which will wrap each of the CDC in it's own class. However, Windows XP SP2 do not have drivers that support this without manually updating the usbser.sys and another .sys file. Updates available at microsoft.com. The SP3 do however include this so it will work without any magic updates.

Dean can probably make this work without any jumpers or such and use the driver (.inf) file for the rev1 of the Xplain. It's in the zip-file for the Xplain at www.atmel.com/xplain.

SuperAVRMan,

The Atmel firmware apparently uses a CDC interface for the programming; what host side application is Atmel using to program the XPLAIN? That method won't work here as my version clones a full AVRISP-MKII (including the V2 protocol and ISP/PDI programming modes) which can't be part of a composite device.

Also, if Atmel has a semi-complete version already made, why isn't it in general use?

I am using Ubuntu 9.04, an avrdude 5.8 compiled from original source with the PDI patch.

With the R2 version it still takes 25 seconds for dumping the first 256 bytes of flash. And avrdude crashes on a second attempt:

Code:

$ avrdude -p atxmega128a1 -c avrispmkII -P usb -t

avrdude: usbdev_send(): wrote 0 out of 1 bytes, err = No error

avrdude: stk500_send_mk2(): failed to send command to serial port

$

The USB interface is still there, and when starting avrdude again I can again read the flash (at the low rate).

So the crash must be something inside avrdude.

Congratulations Dean.

You are a pretty smart guy and I am sure Atmel with consider you in their future plans (Better they do it soon or they will lose the opportunity).

Try using non terminal mode -- that's what I tested with and what appears to work great (with the patched version). Try this:

Hallo,

thanks to Dean for his great work! I've just downloaded the newest LUFA and tried to get the Xplain bridge to work. I could build the project for the 1287 with no errors in Studio 4.18 Build 692

Program: 4190 bytes (3.2% Full)
(.text + .data + .bootloader)

Data: 307 bytes (3.7% Full)
(.data + .bss + .noinit)

Flip succeeded in programming and Windows XP SP3 shows a 'LUFA XPLAIN Bridge' I set the driver to the 'LUFA XPLAIN Bridge.inf' file and get a 'communications port'

But the AVRstudio is not able to connect to an AVRISP mkII using an USB connection.

Does anybody know where the fault is?

Thanks and greetings from Germany

Eumel

Eumel,

The XPLAINBridge code is for making a USB to Serial bridge between the XMEGA and the host for communications -- but not for programming. To be able to make the XPLAIN board appear as a AVRISP-MKII for programming of the XMEGA, you'll instead need to compile and flash the "AVRISP" project in LUFA, compiled for the XPLAIN board.
