Interesting - that's the same board as I'm using. It would be worth seeing what happens. I've had a look at the bbappend for 3.2 that Kishore posted and compared it with the standard one for 3.0. I think it 'just' needs a new meta data branch before I can try a build with pvr. I guess this will need to be a new branch and not an existing one? > > Jim A > > > > >> Cheers, > >> > >> Bruce > >> > >>> > >>>> > >>>> -----Original Message----- > >>>> From: yocto-boun...@yoctoproject.org > >>>> [mailto:yocto-boun...@yoctoproject.org] On Behalf Of Chris Tapp > >>>> Sent: Saturday, October 06, 2012 5:43 PM > >>>> To: yocto@yoctoproject.org Project > >>>> Subject: [yocto] Meta Intel / Cedartrail / Denzil - how to get > >>>> unionfs in the kernel > >>>> > >>>> I' trying to enable unionfs in the 3.0.32 kernel for the cedartrail BSP > >>>> under Denzil 7.0.1. > >>>> > >>>> However, the CONFIG_UNION_FS config flag isn't in the .config ... > >>>> > >>>> Is there something else I need to enable, or do I need to find another > >>>> way? > >>>> > >>>> Chris Tapp > >>>> > >>>> opensou...@keylevel.com > >>>> www.keylevel.com > >>>> > >>>> > >>>> > >>>> _______________________________________________ > >>>> yocto mailing list > >>>> yocto@yoctoproject.org > >>>> https://lists.yoctoproject.org/listinfo/yocto > >>> > >>> Chris Tapp > >>> > >>> opensou...@keylevel.com > >>> www.keylevel.com > >>> > >>> > >>> > >>> _______________________________________________ > >>> yocto mailing list > >>> yocto@yoctoproject.org > >>> https://lists.yoctoproject.org/listinfo/yocto > >> > >> > >> > >> -- > >> "Thou shalt not follow the NULL pointer, for chaos and madness await > >> thee at its end" > > > > Chris Tapp > > > > opensou...@keylevel.com > > www.keylevel.com > > > > > > > > > > -- > "Thou shalt not follow the NULL pointer, for chaos and madness await thee at > its end" > _______________________________________________ > yocto mailing list > yocto@yoctoproject.org > https://lists.yoctoproject.org/listinfo/yocto > Chris Tapp opensou...@keylevel.com www.keylevel.com
