I often encounter situations in embedded development where I need to roll my own solution for logging on an MCU. The standard quick-fix to this challenge is for your application to tie a UART to printf and listen there during runtime. While this is a good start, getting embedded code to a production state will often require more.

In my first fulltime job out of college, the senior engineers who mentored me came up with a simple but flexible solution for logging on an embedded platform which I still use to this day. Here's a quick summary of how it works and how you can implement it.
