What version Yocto are you using?

I'm using 'danny' as that's the latest version which includes video hardware acceleration for the DN2800. > At any rate, I'll try what you suggest in terms of the kernel command line. The README says this fixes the issue for the PVR drivers, but I don't think they're included in later versions. If you've still got problems, it may be worth posting to the meta-intel mailing list as well as that's where Intel BSPs are discussed. > Thanks again, > > John Chris Tapp opensou...@keylevel.com www.keylevel.com -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
