DTB (Device Tree Blob Files) Step by Step Guide DE1-SoC ** HELP ! ** GPIO Q14.0

I am not familiar with that particular board but I can tell you how it works for the Altera Cyclone V Development Kit.

There are separate GSRD (Golden System Reference Designs) releases for each tool versions (13.1, 14.0 and 14.0.1). Each has its own version of GHRD (Golden Hardware Reference Design), including the required XML files. There are also instructions on how to generate the DTB for each version.

See http://rocketboards.org/foswiki/documentation/gsrd

Note that the information required by Linux varies between kernel versions. Also, the Device Tree generator evolved between tool versions (13.1 to 14.0.1).

If the above does not help, I would suggest trying to contact that particular board supplier.
