[PD] miller's gpio on rpi2modelB and the "enable" message

[Peter P.]

Hi list, hi J,

I am better understand the GPIOs on a Raspberry Pi 2 model B using
Miller's gpio external from pi-externs. Everything works fine so far,
only in the help patch kindly provided by J Oliver in his posting
http://lists.puredata.info/pipermail/pd-list/2013-04/102172.html
the message "enable 17" is said to do the same as an
	echo "17" > /sys/class/gpio/export
on the shell, but is has no effect, no file
/sys/class/gpio/gpio17 is created.

If I create in on the console all is fine.

Does anyone else experience this?

Thanks, Peter
