Has anybody else problems to program ATmega168 with Codevision AVR version 1.24.2c. I use stk200 programming cable. There is no problems when using ATmega88 chip. Is there programming software some bugs or...?

I use unfortunately Windows platform, so I can't use newest AVRdude version witch supports ATmega168.

AVRdude 4.3 has no support to ATmega168. Is there any patch to config avrdude.conf file?

Yes, it should be possible to patch AVRDude 4.3's avrdude.conf file to work with an ATmega168.

Here's the relevant entry to add to the file, as extracted from a more recent version:

You should note that more recent builds of avrdude are available for Windows.

It is also possible to build avrdude direct from the online source code under either Cygwin or MinGW.

Apparently the version of avrdude that comes with WinAVR is broken right now in terms of being incapable of verifying signature bytes.

But there have been reports of avrdude 5.1, compiled under Cygwin from the official release (non-CVS) 5.1 source code, working correctly.
