Hi Carsten, > it should work. both imx6 and panda are armv7 devices so even if code is > optimized for armv7 the binaries will work. First of all, Thanks a lot for making my doubt clear. I never got an answer for this on TIZEN-IVI mailing list, and surprisingly, I got that on this mailing list :)! And, may I ask what you exactly refer to, when you say >(i shall assume for now that DEPENDENCIES are met) ? Does it mean dependencies from kernel side, the components needed in the kernel to support particular functionality, like I was asking about EFL??

(but you lose fpu support). efl treats arm just like it treats x86 - neon assembly is runtime detected and auto-enabled IF your cpu supports neon. if it doesn't it falls back to non-neon C code implementations. x86 does the same ?(but checks for mmx and sse3 etc. and falls back a few more levels depending on age). again - it all depends on -march flags when you compile and what MINIMUM cpu arch level it's built for. everything from cortex a8 and up is armv7... until we start talking arm64, which is so new... i have no idea of its specifics. i've never had any arm64 silicon in my dirty little hands. :) > Thanks and Regards, > Prathamesh Ghanekar > > -----Original Message----- > From: Carsten Haitzler [mailto:ras...@rasterman.com] > Sent: 10 December 2013 14:01 > To: Prathamesh P Ghanekar > Cc: enlightenment-devel@lists.sourceforge.net > Subject: Re: Enlightenment support for iMX6 > > On Tue, 10 Dec 2013 06:43:54 +0000 Prathamesh P Ghanekar > <prathamesh.ghane...@igate.com> said: > > > Ok, > > > you don't explain what you used to build the image or even what it > > > contains... > > I wish to build TIZEN-IVI for Freescale board. :) As a starting > > point, I use prebuilt image to run on imx6 board. > > a pre-built tizen ivi image? > > > Surely, it won't run as is on new hardware.
