37 eMMC. An easy way to flash the eMMC is to use the u-boot ums
38 command. The boards are sold pre-flashed with such a u-boot. It is
39 assumed here that the board has already a working u-boot on eMMC and
40 jumpers are set to boot on eMMC. See [3].
42 Jumper configuration for eMMC boot:
46 In case the board was flashed with a wrong u-boot, or the eMMC is
47 erased, u-boot can be loaded by USB Serial Download boot mode, using
48 imx-usb-loader. See [3] and [4].
51 - Plug the micro USB cable from the Debug USB Port, to your computer
52 - Plug the USB Type C to your computer, this will power up the board
54 In the U-Boot prompt launch:
58 This will mount the eMMC content in the host PC as a mass storage device.
60 To determine the device associated to the eMMC card have a look in the
69 directory, ready to be dumped on the eMMC. Launch the following
72   dd if=output/images/sdcard.img of=/dev/<your-sd-device>
74 *** WARNING! This will destroy all the eMMC content. Use with care! ***
86 - put a micro USB cable into the Debug USB Port and connect using a terminal
88 - power on the board, with USB Type C connector.
