Yes, if I don't append the DTB and I set ArcNumber to 1682 then it boots using the ref board setup, if the DTB is appended then it doesn't boot (I configured the kernel to support iconnect, dreamplug and RD-88F6281) > > I've also hit the issue of the stock U-Boot not supporting DTB so am > > running with > > CONFIG_ARM_APPENDED_DTB=y > > CONFIG_ARM_ATAG_DTB_COMPAT=y > > Have you been using the latter option or are you just using the settings > > in your dtb file?

I'll have to give some thought to what to try next. Adam P.S. I note your LED names don't have the platform name in fromnt of them - I thought that was normally included to avoid any confusion with LED names for attached peripherals.
