Installing Openwrt On A Mikrotik Routerboard

I've just acquired a RouterBoard 433UAH and was hoping to install OpenWRT. Using either the svn trunk or branches/8.09 builds I can produce a network bootable kernel/rootfs, however I am unable to access or write OpenWRT to the NAND.

This board has a 512 MB NAND chip instead of the 64 MB one on the RB433AH (at least according to the Mikrotik spec sheets).

We have made a tutorial to make RouterBoard 750GL Openflow enabled. What this tutorial contain:-Installation procedure of OpenWRT on RouterBoard GL750-Installation procedure of Openflow v1.0 on RouterBoard GL750-Installation of NOX/POX/Floodlight Controller-Testing of OpenFlow enabled Network This tutorial can be downloaded from the following link. Install/Cancel - after selecting the router and selecting the RouterOS packages below, use this to start install. SoftID - the SoftID that was generated on the router. Use this to purchase your key. Key / Browse - apply the purchased key here, or leave blank to install a 24h trial. Get key - get the key from your mikrotik.com account directly.

If served up via TFTP the prebuilt Kamikaze AR71xx vmlinux.elf kernel will boot but panics when unable to mount a root file system.

I tried following the NAND erase procedure from the 433AH Wiki Page without success.

Startup messages:

Under the branches/8.09 build I see a single MTD entry (and the single corresponding /dev/mtdblock0 device):

Under the trunk build I see no /dev/mtdblock* devices or entries in the /proc/mtd file.

Attempting to mount the /dev/mtdblock0 device results in:

I'd greatly appreciate any suggestions on how to proceed. I've got some free time and am more than happy to test builds or contribute in any way I can.
