Hi Huanxin Jiang ,
Can you please let us know if you are using imx8MQ evk or custom board? As on i.MX8MQ evk, if we write 1 to TOP command board does goes to power off state.

Thanks Karan and I can also turn off the board if I enter the uboot console and run a "mw" command to set the TOP bit. My failure happened at some later stage (later than the entry to the u-boot main loop) so I'll have a further check.
