Actually I have the proper path you mentioned. I was just typing it over from my pc into my ipad since I was doing multiple things. Ideally I should have opened the forum from the windows machine and copy it over...my wrong.
So I understand that the slashes are wrong and that is probably causing the issue that avrdude cannot run a script or a function. My question is where is that path configured or scripted so I can change the error path char ("/") from
"c:\users\paul\downloads\arduino-nightly\hardware\tools\avr/etc/avrdude.conf"
into :
"c:\users\paul\downloads\arduino-nightly\hardware\tools\avr\etc\avrdude.conf"
I guess the script was probably a cut and paste error from a linux script? Worst I can install the current 1.6.11 version.
