Error burning bootloader atmega1280 & 644P

Specifically could you fill this out:

1. What is the setup (which version of arduino/sanguino/ what board version/ windows or linux etc etc)

2. What was the problem?

3. How did you resolve it? (what specifically changed? Did you have to install drivers on the new install? did you need to reset port permissions etc etc etc)

Computer that did not work:
Acer 3050
Ubuntu 10.10
Arduino 0018
Arduino 0022
Sanguinololu 1.1 and 1.2
Tried different versions of serial rx/tx
Purged Arduino environment and reinstalled (deleted all hidden files)
Re-downloaded Sanguino files (multiple times)
Tried using AVRdude from command line.

Computer that does work:
Dell inspiron 6400 (e1501)
Ubuntu 9.10....10.04....10.10 have all worked
Arduino 0022
Sanguinololu 1.1 and 1.2

Even after burning the bootloader the Acer will not communicate with the board. It always says avrdude: Device signature = nnnnnnnn avrdude: Expected signature for nnnnnnnnn is nnnnnnn. Double check chip, or use -F to override this check.

But I use the Acer to upload to other Arduino devices (168's and 1280's) with some success (lots of re-tries but no mismatches).

Sounds like Acer has lpt1 issue if you are using DAPA method. USB issue if you use it to connect. Need more info on how it connects. Check cables - swap them.

I found this today: http://itpedia.nyu.edu/wiki/Bootloading_the_Arduino--Using_Only_the_Arduino! which seems to describe a method of bit banging through the FTDI chip like you wanted. I have not tried it out yet (I just found it!), but I'll look into it more tonight. If this is possible I'll write up a sanguinololu walkthrough.

So I don't have time now, but I'll try and look at the schematics for the arduino and sanguinololu and see about adding a 4 pin header to the FTDI. Does anyone if the expansion pin holes are connected to the FTDI? I've still not gotten around to really analyzing the schematic.

Maybe Joem can chime in once we know what we need on SL. Pins etc for SL 1.4 next gen.
It would be really nice if it can work with 1.2 or 1.3a.

Note: When I tried this with the Pololu's installed, no faint light with the Parallel port only plugged in. Once I removed the Pololu's I was able to see the faint light.

Which way do you have the pololu's facing? With the usb facing you which side are the screw pots on?

With the USB port towards me, the screw pots are to the right.

Thanks,
Mike
