Oh, you have a debugger you lucky sod. Currently working on a thing (approaching EOL thankfully, but still have to support and add new features until the manufacturer says "no seriously we're cutting you off") that uses a gcc cross compiler from the 90s, no gdb for me. Side channel debugging is a life skill. Oh it's crashing weirdly with no diagnostic output on the UART terminal? Rewrite a timer interrupt that's still running to print your diagnostic information when you toggle a switch. It's actually fun if there's not deadline pressure or a line down situation at a customer.
