👨‍🔬🥱 "J-Link RTT for the Masses," or "How to Overcomplicate Simple #Debugging with #Semihosting on ARM!" Because obviously, what every #hobbyist needs is a dissertation-level guide to turning a microcontroller into a chatty friend. Spoiler: Just use printf like the rest of us 🙄.

@gnomer well it does have *some* tracing and hooking ability these days: https://qemu.readthedocs.io/en/master/about/emulation.html#tcg-plugins but perhaps not enough for your needs. You can get away with a lack of proper OS and HW by using #semihosting which is how a bunch of the M-profile compiler test suites are tested.
