IMO UMS is the most convenient for development. It does require access to the console to hit ctrl-c, whereas you can control booting/rebooting with fastboot (making it nicer for production or for in-field repair). I have found that both fastboot and UMS are far nice to use than SDP. --Sean >> On an imx8mm_evk, I get USB errors after the CTRL+C and ums fails to >> mount after that. > > Do you need to do a USB reset or anything? > > adam >
