Hi all,
I'm trying to get openWRT to work on my dream plug.. I can get the kernel to start but I'm struggling to get the kernel to locate the root partition.
I'm compiling openWRT TRUNK, and selecting "guruplug-server-plus" which does get me a kernel which is happy to load.
I've already upgraded u-boot:
Marvell>> version
U-Boot 2014.10+dfsg1-5 (Apr 07 2015 - 21:53:14)

Has anyone managed to make openwrt boot and run on a dream plug? Any help would be very gratefully received.
