Oh wow! This is quite neat! Unfortunately I went through a different route and built a custom binary for the puck :c (wish I found this wayyy earlier lol). So they could only be programmed via the SWCLK SWDIO pins. But thanks for the share! I will definitely consider porting the code over to vanilla puck.js bootloader and giving it a shot :D
