Hi,
I have an "Iomega Iconnect" which I would like to upgrade to OpenWRT
I have followed this guide "wiki.openwrt.org/toh/iomega/iconnect"
I used the image files from "downloads.openwrt.org/snapshots/trunk/kirkwood/generic/"
The files which are available for my device are the following :
openwrt-kirkwood-uImage
openwrt-kirkwood-generic-jffs2-nand-2048-128k.img
openwrt-kirkwood-iconnect-u-boot.bin
openwrt-kirkwood-iconnect-u-boot.img
openwrt-kirkwood-iconnect-u-boot.kwb
openwrt-kirkwood-iconnect_second_stage-u-boot.bin
openwrt-kirkwood-iconnect_second_stage-u-boot.img
openwrt-kirkwood-iconnect_second_stage-u-boot.kwb
openwrt-kirkwood-iconnect-squashfs-factory.bin
openwrt-kirkwood-iconnect-squashfs-sysupgrade.tarI used the following files as they where close to the ones mentioned within the guide
openwrt-kirkwood-uImage
openwrt-kirkwood-generic-jffs2-nand-2048-128k.img
openwrt-kirkwood-iconnect-u-boot.kwbI followed the guide made a backup of my MAC address and successfully flashed uBoot
This reloaded to the uBoot prompt and I followed the rest of the guide to flash the uimage and jiffs image.
The problem I have is that nothing loads past the uboot prompt after reboot.
This is a console log of what I see on screen :

I can still successfully enter uboot so might be able to correct this.
The question is how? I suspect the guide is slightly outdated.
Here is a dump of the current environmental variable with the MAC address obscured.

Also what are the other images for this device like the uboot second stage loader and a squashfs image which is not recommended for nand flash.
Thanks
