I'm trying to run a simple led blink example like here:
http://www.phys-x.org/rbots/index.php?option=com_content&view=article&id=104:lesson-1-beaglebone-black-blink-led&catid=46:beaglebone-black&Itemid=81
I'm running a Ubuntu image on my beaglebone black with node 0.8.x. I get a
permission problem that looks like some form of failure to have access to
the pins. I added my user to the dialout group and that didn't work. Then
I added my user to every group I could find and that didn't work either.
The only way I can get the code to run and do the blinking is if I run it
as root. My question is, how do I give my user access to whatever is
needed to reach the pins running as non-root. The permission problem looks
like the following:
fs.js:338
return binding.open(pathModule._makeLong(path), stringToFlags(flags),
mode);
^
Error: EACCES, permission denied

Thanks for any help in advance. I'm pretty excited to get this running.
