I have received i.MX8QM MEK board, put it into serial downloader mode, and flashed L5.4.47-2.2.0 release onto the emmc with uuu, and it boots up. But changing those tiny dip switches back and forth to update to emmc is a pain. I saw some posts suggesting "bmode usb" run in u-boot would make it switch to serial downloader mode, but there is no bmode command in the released u-boot. I tried "ums 0 mmc 0" and "ums 1 mmc 0" but neither made the emmc show up as a usb disk over the usb-c connector. Is there a way to flash the emmc without changing the boot mode switches?
