I got my nice new beagleboard and pico projector today and have run
into a few probs.
First off I only got the beaglebard so that I could run the projector
- that's where my interest lies.
OK - i've got angstrom installed and the login screen is being
displayed by the projector. I can log into the angstrom system from
the console on the serial connection no problem but I can't get any
USB peripherals to work ( keyboard, mouse etc ), either by connecting
direct to the board or via a powered usb hub.
Secondly, what i'd like to do is display images on the projector and I
thought that angstrom would have been the easiest way to do this -
maybe a bit of python code or something. But perhaps this is overkill
- any recomendations on how to do this.
Sorry for the ( probably stooopid ) q's.
Regarding the USB problem: a very likely culprit is that you are using
a cable with a Mini-B connector instead of a Mini-A connector. The
connectors look virtually identical and both plug into the BeagleBoard
USB OTG jack. Here's more info:
Here's an experiment to see if this is the problem. While you are
booting Ångström, short BeagleBoard USB OTG jack P1 pins 4 and 5 with
a probe, a pin, or a short bit of wire. This tells Ångström that it
should be a host rather than a device. Once Ångström has booted, you
don't need the short. If the USB devices work after this, you need to
come up with a more permanent way of shorting pins 4 and 5. The pins
are circled in the photo at http://elinux.org/BeagleBoard#OTG.
There are other USB OTG hints at http://elinux.org/BeagleBoardFAQ#USB_OTG_connection_.231.
Hope this helps.
You might try running 'exhibit'.
In the pico demo software (Angstrom): 'opkg update; opkg install exhibit'
Using python is fine as well, but thought you might want a GUI to start.
Many thanks to all replies.
It was a type B cable, so a bit of slicing and soldering and I now
have a type A cable that works quite nicely
All i did was to short pins 4 and 5 with abit of solder.
Once again thanks.
