According to the DE0-Nano-SoC_QSG.pdf document: "Whats the difference between the DE0-Nano-SoC kit and the Atlas-SoC kit? The hardware is the same for the DE0-Nano-SoC kit and the Atlas-SoC kit. The only difference is the getting-started process for the two kits. Users can freely use the DE0-Nano-SoC kit resources on the Atlas-SoC kit and vice versa." > > With the other dts you then should be able to remove > > > > > +#include "socfpga.dtsi" > > > + > > > +/ { > > > + model = "Terasic DE0-Nano(Atlas)"; So with that it would be more precise to name it DE0-Nano-SoC (Atlas)? It would be than different to that in the linux kernel? But then was up till now not aware that there is a DE0-Nano, a DE0-CV and a DE0 board. http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=56&No=364 But the only one with a processor is AFAIK the DE0-Nano-SoC. > It looks like Steffen is right. > > The board model name is wrong. > > Here is the DE0-Nano-SoC (Atlas-SoC) board: > http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=941 > it is based on Cyclone V SE 5CSEMA4U23C6N.

There is no processor in here, so you have a hard time booting this with barebox (at least without a softcore processor). Will do the other suggested dts changes suggested by Steffen.
