It's certainly been my hobby for the week. It was ok once I got it working, but I got very close a few times to tossing in the towel when the tools weren't working. Other folks <https://groups.google.com/d/msg/beaglebone/jeiOPrPMecM/RCqcG27OBQAJ> have apparently run into this too and given up, including a friend of mine who turned me on to the BBB before he actually tried it and hit similar walls. The OP of this thread has been great though -- powered me past those road blocks with the flashed OS and latest debian from TI. Started moving much more quickly after that. > > If memory is serving me correctly yes, you're using a blue. > Nope, I have a black only. Didn't realize there was a blue, actually. Only knew about the green alternative. Sorry; I've been using the term "BBB" assuming that referred exclusively to the black. But I can see where if there's also a product called "blue", BBB might refer to that too.. gah. Sorry if that confused anyone; all my replies have been *only* about the black. So yes, buy a beaglebone, take it home, and start experimenting. Then I > would probably not worry about HAVING to have hardware connected up with > it. There is a lot you can do by experimenting with software only.

Also I tried the GPIO demos without an LED hooked up just to see it run, but was getting similar errors (prussdrv_open() failed, etc), so I didn't even bother with hardware until the OP got me past that. Hoping to be spinning stepper motors tonight via the PRU.. looking forward to it! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
