I actually set up a build to get a vexpress-a15 booting in qemu with neon support. However, I didn't use the yocto kernel and just pointed at my own defconfig and kernel version 3.10.7. If it would be helpful for you, I could put my changes up on github. The weirdest thing was if I just used the defconfig that is in the kernel for vexpress it wouldn't boot, I had to tweak it a bit. > Best regards, > > Elvis Dowson > _______________________________________________ > Openembedded-core mailing list > Openembedded-core@lists.openembedded.org > http://lists.openembedded.org/mailman/listinfo/openembedded-core _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
