Badger 2040 debugging

I’ve managed to get a lot of things to work on my Badger 2040 but I’m missing an easy way to do debugging. I’ve created a program which creates a logging file on the file system, which I can read after testing but it is not always easy to understand what is going on unless you have online access to debug information. Am I missing something or is this the only way - unless I hook up a full debugger to the system?
