Re: Passing kernel arguments - SAMA5D4EK

[Doug Brainard <dbrainard@brainardinsight.com>]

Sascha,

Okay this is probably a dumb question because I'm fairly new to git,
but I've got everything working with the new environment and checked
in locally, but now when I try to do a "git push origin master", I get
an access denied error:

fatal: remote error: access denied or repository not exported: /git/barebox.git

What do I need to do to push the changes back up?

Thanks,

Doug
