I did something similar with CMake and a lot of the details are incredibly challenging to piece together. Everyone just blindly copies existing linker/startup scripts. Very low level articles like this are rare and invaluable I spent a month and got things working with a modern toolchain C/CMake/GCC/OpenOCD but gave up on further work bc I couldn't nail down a lot of details. micro programming outside arduino is painful and backward. it's stuck in the 90s https://geokon-gh.github.io/bluepill/ https://geokon-gh.github.io/bluepill/
