hello,

I have trying to install maemo5.0-alpha on beagleboard(C2) but I have problems with kernel modules. When I boot the beagle I get following error:

I have done installation as told in
http://maemo-beagle.garage.maemo.org/alpha.html

Any thoughts how I could fix this problem?

Hi,

the beagle port of the alpha sdk is facing the problem that the contents of some of the repositories it uses have now been updated to the beta release. Maybe your problem is related to this as your rootfs may include stuff from the beta repository.

I recently did an accidential update of my existing alpha sdk based setup and i also ended up with core dumps etc.

But currently the alpha sdk based solution isn't very useful anymore, anyway as e.g. all software in extras-devel was compiled with the beta sdk and doesn't install on the alpha-sdk based beagle solution.

MoG

Yep, so it seems that I have messed up with those repositories, but anyway, I don't get installation of alpha version working anymore with given installation files, at least rootfs, uImage and modules seems to be right but making rootfs fails.

Is beta version installable on beagle?

Have you tried asking in the support forum of the Maemo on Beagleboard project? https://garage.maemo.org/forum/?group_id=880
