Hmmm... it looks like your name got truncated, or maybe mine got extended =:-)}}} I put FDOM on a large ~300MB partition of the microSD card with the rootfs in /dev/mmcblk0pr and the kernel in /dev/mmcblk0p4/boot/ In order to get it to boot, I put a soft link at the card's root pointing to the desired kernel (I have two of them in there at the moment), thusly: (as root in where /dev/mmcblk0p? is mounted) # ln -s boot/long-kernel-name.bin uImage.bin There are still a bunch of things I need to get correct about booting from the microSD card, but it does boot from just one partition.
