Hi Suresh. I'd start with the Linaro Precise Nano rootfs and work your way up from there. Nano is a minimal hard float system that has a serial console, networking, apt-get for new packages, and that's about it. I'm not sure what your SoC needs to boot. You could try using linaro-media-create to create a Versatile Express image, grab the finished rootfs out of that, and then use it on your device. Something like: * Grab http://releases.linaro.org/12.04/ubuntu/precise-images/nano/linaro-precise-nano-20120426-108.tar.gz * Grab http://releases.linaro.org/12.04/ubuntu/precise-images/nano/hwpack_linaro-vexpress_20120424-1_armhf_supported.tar.gz * linaro-media-create --dev vexpress --image-file vexpress.img --hwpack hwpack*vexpress* --binary *nano* --hwpack-force-yes * sudo kpartx -a vexpress.img * sudo mount /dev/mapper/loop0p1 /mnt * Grab the initrd from /mnt * sudo mount /dev/mapper/loop0p2 /mnt * Grab the rootfs from /mnt I believe you need the initrd to boot. -- Michael _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
