The board(s) in question were not supported by u-boot. So someone (the 'You') needs to add the support in the source tree before u-boot will work on those board(s). > > Please read the top-level README -- especially the section "Building the Software." Virtually all GNU projects (and most open-source projects) contain a file named README. It's actually part of the GNU coding standards: gnu coding standards:<div class='quotetop'>QUOTE </div> --- Quote Start --- The distribution should contain a file named ‘README’ which gives the name of the package, and a general description of what it does.[/b] --- Quote End --- You should read the README file. In this case, it contains a section relevant to the discussion (how to add support for a board). > > For the Altera Cyclone II board, you can use any of the existing Altera boards as > > a starting point (e.g.: board/altera/ep1c20). In many cases, boards based on the same CPU architecture (e.g. Nios-II) can use the same or similar code. The common way to add support for a board is to just copy the code for an existing board and then make the necessary changes. In this particular case, the code in the board/altera/ep1c20 tree (or "directory hierarchy") is a good choice as the source of the copy. Hope this helps. Best Regards, --Scott
