Fortunately, writing software for computers is often done, well, on a computer, meaning that while writing programs we can run other programs that help us understand the behavior of what we are writing. Typically the machine we are writing software for, though it may run in a data center and have a d...| danielmangum.com

In this post we’ll take a closer look at that “Hello, World” application, diving into what happens prior to printing our message to the UART console.
