Fastboot flashing not working on iMX8M Mini DDR4

[Hrithik]

Hi NXP Team,

We are working on Android 11 on iMX8M Mini DDR4 board.

.
When we try to flash android images using fastboot, it gives following error:
FAILED (remote: device is locked.)

When we try fastboot OEM unlock command, it gives below error:

FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed

When we try fastboot flashing unlock:
FAILED (remote: unlock device failed.)

We tried both "adb reboot fastboot" as well as "adb reboot bootloader".
Fastboot device is detected after the command but not able to flash after that.

We got one log after UUU flashing - In boota get fastboot lock status error. Set lock status

Kindly help us in solving this issue.

Thanks.

Hi 

Please try to enter uboot fastboot mode:

Hi @Zhiming_Liu ,

Thanks for the reply.

But we had tried all these commands prior to posting it here.

We resolved the issue by enabling the "trusty" flag in the defconfig.
