Hi Zhaowei,
The following suggestions are for your reference:
1. Use uuu -b emmc u-boot.imx (here should be your bootloader's name) to flash the bootloader, other images are not downloaded to the board.
2. Boot board
Power off the board and configure it to boot from eMMC to check whether it can boot normally.
3. If the above method fails to start the board or the download is abnormal, then find the problem on the hardware. Mainly find the problem on SMT.
-------------
以下建议供您参考:
1. 使用uuu -b emmc u-boot.imx( here should be your bootloader's name)命里烧写bootloader,其他的image不是下载到板子。
2. boot板子
给板子断电,并配置为从eMMC启动,检查是否可以正常启动。
3. 如果上述方法,无法启动板子或者下载不正常,那么要在硬件上查找问题。主要在SMT上查找问题。

Have a nice day!
