I know a few guys here have used the Olimex AVR-JTAG Ice. I received mine today but as yet have still not got it working. Does anybody have any ideas of what may be wrong?
I have the USB version of the Ice model Olimex AVR-USB-JTAG.
I am using a STK500 board running AVR Studio 4.12.460. Also in the about box it was reported as GUI Version 4, 12, 0, 460, JTAG ICE 1, 0, 0, 39, ATMEGA16 203
First I made sure I had a running asm program (just something to switch the lights on and off). The fuse setting were correctly set to JTAG Interface Enabled; (JTAGEN=0) which was Ticked.
The connections to the portC and portE(for reset) were as per Official Atmel connections for “ICE to MEGA 16/32â€
Just checked with a meter, pin 2 and 10 of the JTAG connector are connected internally together so they are getting the required ground 0V from the target micro.

The target board is the stk500. The connectors PortC and PortE are on the board itself. All the voltages are available at these pins therfore yes the ICE is being powered. The ATMega16 is actualy on one of the test sockets on the board (SCKT3100A3), so all of the voltages have to be present. The SKT500 has many leds to show power/staus etc and the progam I am running flashes differnt indicator leds (also built into the SKT500 board). This program is working so the chip is good.
When the JTAG USB Device was first plugged into the RS232 and powered up and AVR STudio was started should it have ungraded the firmware? I just assumed because it didn’t that there was no need as it was pre programmed for the latest version of AVR STudio. It has never asked for an upgrade or requested the ebn file, is this normal?
