Quick start application for BeagleBone with supplied software & LCD7 cape?

GoogleGroups
1

Will someone suggest software which will run on an “as delivered” A5 BeagleBone with the circuitco LCD7 cape. I have purchased a couple of these and it would be assuring to see the display and touch screen function (more than a console) as baseline before modifications begin.

I am working toward a machine control HMI using Qt, any help with that would be great. I have read many conflicting approaches, or explanations to short for me to follow (not or lack of trying).

Thanks,
David

Download the most recent angstrom image and dd it to the sd card.

Thanks Koen,

Just tried that for the second time.
Result from last try to a

david@david-VirtualBox:/media/sf_Ubuntu_shared$ xz -dkc An* | pv | sudo dd of=/dev/sdb

First try I thought had no error, but both result the same, beaglebone start image, then nothing, no blinking leds.

The SD card that shipped would come up with login prompt.

Help!

Something must be wrong with your download. Check the md5sum and size.

Koen,

The image you downloaded is not complete. This happened to me too. Try downloadingthrough links mirrors.

http://www.beagleboard.org/angstrom-mirror/www.angstrom-distribution.org/demo/beaglebone/

http://angstrom.s3.amazonaws.com/demo/beaglebone/index.html

Once downloaded, check the size in bytes of the image.

Oh, I just didn’t expect that, you are right the MD5 doesn’t compare, thanks Jason.
Nilson: Just in case I am downloading from mirror as you suggest, thanks.

Worked! Thanks.
Result of several hours of SD card writing yields a very impressive desktop working on the LCD7 complete with applications showing off the system.

Now (pushing my luck) is there a straight forward way to add Qt ?

grateful for what I have,
David

opkg update ; opkg install kate

That should give you qt and a sample app (the kde text editor 'kate').

Thanks Koen,

opkg update

after downloading and updating about 6 other files I get this message;

tryed this anyway

opkg install kate

Collected errors:

  • check_data_file_clashes: Package kdelibs4 wants to install file /etc/xdg/menus/applications.menu
    But that file is already provided by package * libgnome-menu2
  • opkg_install_cmd: Cannot install package kate.

I appreciate the help, thank you!

Thanks Koen,

opkg update

* opkg_download: Failed to download http://feeds.angstrom-distribution.org/feeds/v2012.05/ipk/eglibc/armv7a/machine/beaglebone/Packages.gz, wget

Haven't seen that one yet

tryed this anyway

opkg install kate

In this case --force-overwrite is safe, so:

opkg update ; opkg install kate --force-overwrite

The menu structure will look a bit different after that.

Thanks Koen, that did it!

I really appreciate your help.
