Atmel Atmega128L and Macgraigor Wiggler

Started by Pat Barlow September 27, 2004
We are regularly programming an Atmeg128l board with the Atmel JTAGICE
+ AVRStudio with no problems, but in production it would be useful to
use a MacGraigor Wiggler to program the Atmel, as we already have one
in our test/programming jig.
MacGraigor don't support the Atmel AVR devices, but I reckon there
should be a software solution to this, does anyone know what it might
look like?
TIA.
Pat.

Hi, I have written code that will program JTAG capable AVRs using an Altera Byteblaster interface. Changing a few #defines is all that is necessary for it too work using the wiggler. If you want the source, I can email it to you. Regards Anton Erasmus
Try the Olimex AVR JTAG: cheap but weak.
If you make attention at the connection sequence (1-attach the jtag 2-power
on ) it is a good alternative to the strong but expensive Atmel Jtagice.

Anton - I would certainly appreciate it if you could forward it, the email above is valid if you send it through to that. I assume that the byteblaster is a similar type of device (parallel port -> jtag i/f)? I'm also assuming that the Wiggler is basically just a buffer/logic level translator and doesn't contain any special hardware (shift registers etc.), do you know if that is the case? Any help appreciated, Yours, Pat.

Or try the low cost Chameleon POD from www.amontec.com. It can clone a large part of the popular dongles in the seconde. - Wiggler - Raven - Xilinx Parallel Cable III - Olimex AVR JTAG - Altera ByteBlaster - Lattice ISPdownload - Lart dongle - Atmel AVR STKx00 cable - PSD FlashLINK - and much more All the configurations are FREE and are provided by the Chameleon POD programmer freeware!

Yes the Byteblaster is Alteras JTAG dongle which is just a 74HC244 buffer connected to the parallel port. The wiggler is the same just using different bits for different signals. Regards Anton Erasmus

Anton, I'd be interested too in some code using the Alter Byteblaster for the AVR. Rene -- Ing.Buero R.Tschaggelar - http://www.ibrtses.com & commercial newsgroups - http://www.talkto.net

I really do not believe about this one, this is not JTAG dongle i.e. state machine with some outputs but AVR chip with firmware inside, I doubt you can clone this with these limited macrocells CPLDs you are using in your POD, this make questionable all other claims you make too Cheers Tsvetan --- PCB prototypes for $26 at http://run.to/pcb (http://www.olimex.com/pcb) PCB any volume assembly (http://www.olimex.com/pcb/protoa.html) Development boards for ARM, AVR, PIC, and MSP430 (http://www.olimex.com/dev)
