Beaglebone GPIO1_7


I just bought a beaglebone, and its a cool little device, despite its
much a pretty steep learning curve.

For example using pin P8_4 (GPIO1_7), is not set to GPIO on boot. It
took a while to understand why it worked in bonescript, but not using
the shell, mrbbio or pybbio. Or that once a bonescript version of a
program ran once, the others would also work until next reboot.

And the only place that documents how to change the mode of a pin, is
the bonescript code... That is one steep learning curve to make an LED
blink on a predefined gpio pin.

Anyway, just some food for thought. This was initially going to be a
question, but then I dug a lot deeper while asking it, and it turned
more into a rant.
