Having received firmware upgrade 110 in late January I finally got round to installing it tonight. I’ve got an Atmel STK500 development kit which was used for the upgrade together with Atmel Studio 6.2 running on a winxp machine.

The hardest part was, as others have noted, convincing myself that I understood the correct orientation for the cable between the STK500 and the urad-monitor. To confirm the correct orientation, before connecting the programming cable, the unit was powered up using its normal 5V supply and then the voltages checked on the ISP pins on the pcb.

Following this, and again without a connection between the unit and the programmer, the programmer settings were adjusted to suit the job in hand.

With the target voltages set, the unit can be connected to the programmer and the device information read using the programmer.

The final step is to write to the unit.

All went according to plan with the unit back on line.
