Hi,
I'm trying to have a version working for netgear wnr3500 lv2. As you may know there exists Openwrt images for this device but they do not work at all, the device getting bricked after flash.
I've found ways to build images that I can flash, and where the kernel boots (openwrt kernel or hand built kernel). But I can't get the flash/nand device to work so I cannot mount any root fs. I've tried to add many drivers in my hand built kernel but it does not change anything for now:

I don't understand what more can be included in dd-wrt kernel, that is not openwrt or lede or my hand-built kernel. Any help would be much welcome!
