Re: [avrdude-dev] [bug #40748] linuxgpio doesn't work on Raspberry PI rev. 2.

What error are you getting?

In 6.3 you need to compile with rev 1388 for linuxgpio.c which fixes %ud

Re: [avrdude-dev] AVRDUDE Manual: Error Codes

[Mike Brandon]

-116 isn't an error code, it is the nbyte value... See the code in the
usbtiny.c file starting at line #162 though line #187
