Write .bin from one m5stack to another...
It's possible to write bin via type C usb?
What's your specific thought? I don't really understand what you mean.
Hi @yellowelise are you planning on designing your own firmware? of course, when you flash your m5 device with our burner software it is flashing a .bin file a .spiffs file and a few other files, you can also do this by command line if you choose with esptool. It would be good for you to expand on your questions more so we can better help you.
