In order to understand some of the motivation behind compiling a U-Boot script, you will develop a U-Boot script that will give you the option to TFTP boot the DE1-SoC. Using a compiled script is a more systematic approach that allows us to better manage changes to the default environment and roll back any changes that resulted in unwanted results. The results is that a seemingly minor change in a single environment variable can lead to problems in the boot loader and result in a system that does not boot. In fact, many environment variables are nested within other environment variables. So if you can configure U-Boot from the command line, why would you take the time to compile a U-Boot script? Most U-Boot environments have a large number of environment variables. The resulting file will then be loaded at start up and the commands will be executed as they appear in the script. U-Boot parameters can be set using the U-Boot command line, but instead of manually setting the parameters at the command line, we are going to add the U-Boot commands to a script and compile the script. If someone farts in a sub would all hands be stuck smelling it for weeks? While you’re mulling that over check out some other fabulous creations by Ciamosław Ciamek in our archives.When using U-Boot, there is a set of configurable parameters stored in U-Boot that affect how the CPU will be initialized. As stunned as I am by this amazingly detailed creation, I have a burning question that perhaps some of you can answer. I’ve been in the US Navy myself and while I have served on three surface ships, I’ve never been on a submarine. I like that a seagull has decided to hitch a ride. Here we see some of the crew manning the guns and getting what is undoubtedly some much-needed air. Thankfully this builder has also provided several closeup photographs, this particular one is amidships and the superstructure. The model is of such a grand scale that it can be easy to lose sight of small details from afar. Lastly, we have the diesel engines room and electric engines, and the aft torpedo room. Next, we have the control room with the conning tower, then the petty officers’ quarters. The first module represents the forward torpedo room and crew compartment while the second houses the officers’ quarters, radio, and listening room. This photo highlights what the port side looks like with the hull intact but it also illustrates the model broken into six modules that accurately represent how the real vessel would be compartmentalized. Here’s a view with the port panels removed to view the interior spaces. The hull panels can be removed on both the port and starboard sides. In case you were wondering this is the same type of U-Boat from the Das Boot movie, which, in my opinion, is one of the tensest and most exhilarating movies ever made a worthy watch if you haven’t seen it already. It also took staggering four-and-a-half years to build. This model has roughly 15,000 pieces and is about 70 inches or 177 centimeters long. That would be the case with this stunning LEGO 1/38 scale U-BOOT TYP VII C built by Ciamosław Ciamek. Sometimes something comes along that has us simply awestruck.
