imx6q android P can't boot after fastboot oem unlock

[fdact]

Hi，
   My boarid is imx6q and works on Android P9.0.0_2.2.0 (4.14.98 kernel).
The compiled version of android P is userdebug. It tells me that the "device is locked" when I use
"adb remount". when I do follow the steps, the android P can't boot:
    1.go to setting -> system -> Developer options -> OEM unlocking
    2.adb reboot bootloader
    3.fastboot oem unlock
    4.fastboot reboot

the log stop here,and system is not running:

zram0: detected capacity change from 0 to 536870912
logd.auditd: start
mkswap: Swapspace size: 524284k, UUID=3702fdde-cd96-4fe0-872c-3a98fb38ee5e
Adding 524284k swap on /dev/block/zram0.  Priority:-2 extents:1 across:524284k SS
random: crng init done

Attached is the complete log.

Thanks.

Hello,

Are you able to see your device in fast boot mode with ./fastboot.exe devices?

Best regards,

Hi, zero zero 

We have built the Android 9 by following the steps given in the attached Android User Guide. I am able to reboot the board with fastboot reboot command.

Let us know if you are facing the issue with these steps.
