Hi,

You can try the following steps:
1. download I.MX8M NANO demo image

For example:

2. decompress it on your windows 10
3. download uuu tool

4. copy uuu.exe to demo image directory
5. download images to sd card on board
--setting board usb donwload mode via boot_mode[3:0]
--setting board from SD card via switch on base board(SW1101/SW1102)
--connect usb type-c to pc usb on base board(J301)

--These commands can be used:
