I can't help much, because I do not own any N8x0 device, but you should probably visit [0] (and update it once you get stuff working :)) The omap platform is currently moving over to Device Tree [1] based booting, so you come at the right time to test DT based booting on your N810. Building a DT kernel for your N810 works like this: enable the following config entries: CONFIG_ARM_APPENDED_DTB=y CONFIG_ARM_ATAG_DTB_COMPAT=y CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND=y CONFIG_PINCTRL=y CONFIG_PINCTRL_SINGLE=y and build zImage like this: $ export ARCH=arm $ export CROSS_COMPILE=arm-linux-gnueabi- $ make zImage $ make omap2420-n810.dtb $ cat arch/arm/boot/zImage arch/arm/boot/dts/omap3-n900.dtb > zImage Be aware, that the DTS file seems to lack display & keyboard support at the moment, so you may want to start building a serial adapter first. See [2] for details on this. This may seem like lots of work, but it really makes things much easier.
