So after rather a lot of faffing round related issues I got to the bottom of this problem which turned out to be 'kernel too old'. The Linaro Foundation 3.8 kernels I was using doesn't work in this regard. Changing to last month's release (and munging the kernel command line with the very cool kcmt utility works fine). So, I've now uploaded A saucy armhf/arm64 configured multiarch image and tarball to: http://people.debian.org/~wookey/bootstrap/rootfs/ 2G disk image: (as 92MB file) http://people.debian.org/~wookey/bootstrap/rootfs/saucy-arm64-multiarch.img.xz Corresponding kernel: http://people.debian.org/~wookey/bootstrap/rootfs/linux-system-foundation.axf tarball of same rootfs: http://people.debian.org/~wookey/bootstrap/rootfs/saucy-multiarch.tar.gz All linked on https://wiki.debian.org/Arm64Port#Pre-built_Rootfses Wookey -- Principal hats: Linaro, Emdebian, Wookware, Balloonboard, ARM http://wookware.org/ _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
