set-public-key AVB

[xuantambk]

I am trying to set public key for board IMX8QuadXpus... Android Auto.

Android P9.0.0_2.3.3_AUTO-ER 

After i set random key for rpmb

fastboot oem set-rpmb-random-key

I got error 

AVB ReadVbmetaPublickey:256 Missing Public key file...

And then Device cannot boot to Bootloader any more.

Is there any way to boot device into bootloader mode?

I tried with u-boot-imx8qxp-mek-uuu.imx... load via usb gadge..

But this bootloader uboot dont support below command:

 
fastboot stage ${your-key-directory}/test_rsa4096_public.bin
fastboot oem set-public-key

--> Command not supported?

then init fastboot service
