Outdated avr-toolchain

Outdated avr-toolchain

Hi,

Our avr-toolchain is very old and outdated. Our version is 5.5.0,
whereas the latest seems to be 10.2.0. We also have multiple versions of
the avr-toolchain packages along with functions to produce those
multiple versions. Can we remove these functions and different versions,
and keep only one latest version of the avr-toolchain?

I have an old patchset[1] to this effect, but I didn't want to proceed
without a discussion. I was concerned that there might be a use, for all
these different versions, that I did not comprehend.

Thanks,
Arun

As one of the people using avr-toolchain, +1

I don't think so.  The AVRs are so tiny and development using them is usually
done by copying library source code into your project, so I cannot see any
reason to care about different gcc versions for AVR.

avrdude is another matter--it's very easy to break that if you don't actually
test it.

Thanks for the clarification. I have pushed to master a patchset that
makes avr-gcc track the version. So, our avr-gcc is now version
7.5.0. And, I have replaced the various avr-toolchain functions with
simple variables.

True, I too have an ISP programmer that only works with an older version
of avrdude.

Cheers!
