[En-Nut-Discussion] SPDuo and AVRStudio 4

[Andreas Heinzen]

Hello,

as http://www.ethernut.de/en/isp/spduo.html tells, it may be a problem to use
SP Duo in AVRStudio. Because AVRStudio ask you every time to upgrade your
firmware and this may damage the programmer.

In may case the SP Duo respose of an CTRL-v in Hyperterm is:
SP Duo v2.1

The message from AVR Studio is:
An AVRISP with firmware version 32.31 has been detected.
The firmware version corresponding to this installation of AVR Studio is 2.0A ...

So I made a support request to ATMEL and the solution is to modify some registry keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Atmel\AVRTools\STK500/VersionMajor=32
HKEY_LOCAL_MACHINE\SOFTWARE\Atmel\AVRTools\STK500/VersionMinor=31

Now you can't accidently let AVRStudio do an upgrade.

It works.

Have a nice day

Andreas Heinzen
