Re: [avrdude-dev] [bug #40831] LUFA AVRISP-MKII fails with avrdude 6.0.1

[Colin O'Flynn]

Hi Joerg,

Did you have a chance to look at my partial patch (partial as it doesn't
have STK600 stuff in it yet)? It's posted as the latest comment at
https://savannah.nongnu.org/bugs/?40831.

I'm not in a rush, but if we wait too long I'm liable to forget exactly what
I was doing before, making it harder for me to fix/improve the patch ;-) 

If it seems OK let me know & will give the STK600 stuff a try too. I'll need
someone else to verify that portion as don't have that hardware.

Regards,

  -Colin O'Flynn

No, no trial & error, please.

If at all, then apply a proper heuristics straight from the beginning.
For the Atmel tools, the EP numbers are well defined, so checking the
algorithm against these definitions should be easy.  For the remainder, the
algorithm must be clever enough to always detect the correct EP setup
situation.

The goal must be to have no hardcoded EP numbers in the code anymore.
