Hi there!
I'm trying to install OpenWrt on a Netgear Stora low cost NAS. As far as I know, this is still untested.
For now, I've gained access to the bootloader through the serial console:

***** Here the device appears to "hang".Since I'm not even quite sure of the right target, I tried that both with orion and kirkwood uImage.
I fell a little bit stuck here, so I'll be glad for any hint or advice 
Thanks in advance.
