Hello Joerg,

I cannot help but notice that the latest release of avrdude (6.3) still has this issue.
Is there a reason no update was ever put out?
I'd really like to see this work for linuxgpio to work correctly out of the box.

At this moment I'm trying to resurrect a arduino nano that has no bootloader, and I got it to work using this information, but still...

With kind regards,

Floris Groenendijk

Ouch.  Thanks for reporting!

Fixed in r1388.

snprintf() is being used in linuxgpio.c to convert unsigned GPIO numbers. A recent commit has changed the format from "%d" to "%ud". "%u" is a valid conversion specifier, while the trailing 'd' ends up being printed (e.g. '17d' instead of '17').

This causes GPIO setup to fail:
Can't export GPIO 17, already exported/busy?: Invalid argument

Please replace "%ud" with "%u".
