Where did you get this device, seems someone has swapped the interior

remark , if you find the right chip then stil you need an u-boot version that you can put in flash.
I compiled the one for d2net_v2 in the meantime but that will be of no use to you, I will look if I can find the source for d2net (orion), not on short notice however, but if someone can point were to find it then it might be faster
