Hi,

Following this tutorial http://wiki.ros.org/hydro/Installation/Angstrom, I first tried option 1. I have Angstrom with kernel 2.6.32, but I followed the instructions which left me with a ruined BeagleBoard-xM system. Several other "users" had been created, I could no longer log in as user, only as root and ROS was not installed. After flashing the kernel again and running git, I checked using "opkg list" for ROS packages and none were available. So I guess the recommendation should be "only with latest kernel". Then I build an image, but after building it I can't find the image. What is it called, where is it? Then I used bitbake for cross-compiling ROS. When that finished, I checked for ROS packages and found none. Where should I find them ?

Edit: I tried to create the image again and this time it even goes wrong before the image is finalized giving this error:

NOTE: Error during finalise of /home/<user>/devel/setup-scripts/sources/openembedded-core/meta/recipes-extended/images/core-image-lsb-sdk.bb ERROR: ExpansionError during parsing /home/<user>/devel/setup-scripts/sources/openembedded-core/meta/recipes-extended/images/core-image-lsb-sdk.bb: Failure expanding variable toolchain_create_sdk_version: ExpansionError: Failure expanding variable METADATA_REVISION, expression was ${@base_detect_revision(d)} which triggered exception OSError: [Errno 12] Cannot allocate memory NOTE: Error during finalise of /home/<user>/devel/setup-scripts/sources/openembedded-core/meta/recipes-extended/images/core-image-lsb-dev.bb ERROR: Command execution failed: Exited with 1

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

I guess I'm doing something wrong, but no clue what....

Hi,

The problem is the combination of Angstrom and ROS. When I install Ubuntu I can install ROS groovy (and hydro) without a problem. The problem is that I want DSP as well, which is actively supported by Angstrom only.

Maybe I wasn't clear enough about this, but my latest attempts were building the image following http://wiki.ros.org/hydro/Installation/Angstrom, options 1 and 2, so I did follow http://www.angstrom-distribution.org/building-angstrom. The first time it seemed to go fine, just couldn't find where the image was. The second time, the building ends in the reported errors.

Will be followed up...

Hi hvn,

As we already discussed through http://beagleros.wordpress.com/2013/07/01/roscore-and-rosnodes-working/ there's no support for the BeagleBoard-xM but you're welcome to do it and provide feedback of your results. I don't think the Ångström feed has the beagle-ros recipes cross-compiled for you either so you should do it yourself (check it for your architecture http://www.angstrom-distribution.org/repo/. If you cross-compile them yourself there's no need to search in the feed, just install them.

Regarding your issue, it seem you're having trouble with Ångström and not with the Beagle-ROS recipes. Did you try building simple recipes? Maybe you could start building an image for your board following http://www.angstrom-distribution.org/building-angstrom?. You should make sure that your Ångström build environment is properly set up before trying to cross-compile the Beagle-ROS recipes. If you're still having issues ask for help http://www.angstrom-distribution.org/contact.
