Code

Running on Linux

(Update: Word from Atmel is this will be able to be supported under libusb. Seems likely. :-) See above.)

All the software supplied from Atmel appears to be Windows only. The underlying USB implementation based on WinDriver does seem to have a Linux version also. WinDriver 9.20 USB User's Manual.

It seems Xilinx hardware/software may use a similar implementation, see these for possible pointers:

The driver seems to use 'windrvr6.o' or platform specific variations thereof.

Tools

At this stage all the firmware appears to be binary only. So in order to do some poking around:

Project Log

srec_cat 3290.infile.hex -intel -o 3290.outfile.bin -Binary

import socket

import time

s = socket.socket()
s.connect(("127.0.0.1", 27000))
s.send("\xaa\x02\x00\x00\x41")

time.sleep(0.5)

print repr(s.recv(1))
s.close()

## Connect and start terminal
#avrdude -p atmega3290 -c avrisp -P /dev/ttyS0 -t -v -F

## Dump the flash of the chip to file
#avrdude -p atmega3290 -c avrisp -P /dev/ttyS0 -v -F -U flash:r:"3290.download.b0rked.bin":r 

## Upload the original hex firmware to the chip (the '-e' isn't strictly necessary)
#avrdude -p atmega3290 -c avrisp -P /dev/ttyS0 -v -F -e -U flash:w:"../3290.infile.hex"
