Avrdude does not work with Arduino 1.8.10

[egilkv]

Trivial fix in megaavr/platform.txt:

tools.avrdude.path={runtime.tools.avrdude-6.3.0-arduino17.path}

What error do you get? I prefer not to hard-code the Avrdude version every time there's a new release either.

[egilkv]

Did not note down exactly, but could definitely not find avrdude, probably because of undefined macro. No idea if there is a suitable version independent variant.

No issues here.
This is the output (on Mac) when building the blink sketch on a 100% clean Arduino 1.8.10 install without any boards manager packages installed:

I see no avrdude in your log, I see only the compiler and linker etc. The problem for me was the upload step, i.e. using avrdude. I did install the new Arduino using install.sh, which I assume removes the previous avrdude version.

[MCUdude]

You're right. The Avrdude path is fixed in db73134

Excellent!
