Setting the startup code is not inherently difficult but beware: some of the nastiest bugs you will ever see on bare metal can come from the startup code.</p> <p>What is actually needed to start the execution of the main function? Well, there are a few things that the C and C++ language specifications assume when starting a new program. Some of them are:</p>
