Fastboot doesn't work well

s_inamura — Wed, 06 Nov 2019 02:45:42 GMT

Hello,
I am building Secure Boot environment with iMX8MINI board.
but now I cannot build it because of following result.

[host os (Ubuntu) terminal]
$ sudo ./fastboot oem set-rsa-atte-key
FAILED (remote: command not defined)
Finished. Total time: 0.004s

[U-Boot terminal]
$ Unknown flashing command:oem set-rsa-atte-key

I understand that above U-Boot's message means the U-Boot program do not support trustyOS option for fastboot command.

I builded android_build following command lines at host os.

$ source build/envsetup.sh
$ lunch evk_8mm-user
$ make 2>&1 | tee build-log.txt

I refered to these steps with i.MX_Android_Security_User_Guide.pdf page 3.
and I executed fastboot_imx_flashall.sh to flash U-Boot image to eMMC boot area.

How can I execute above fastboot command ?
and
Please teach me correct build steps if above steps are wrong for to build Secure Boot environment.

Best regards,
Seiji Inamura

Hello,

To support Trusty OS in standard Android enable in evk_8mm.mk:

PRODUCT_IMX_TRUSTY := true

Thank you,

Best regards,

Hello Aldo,

Thank you for your reply.

> PRODUCT_IMX_TRUSTY := true

I didn't set this parameter ,so i set it in evk_8mm.mk and builded codes and flashed images.

However fastboot command reported the same error message.

Do you know other options for Trusty OS ?

Best regards,

Seiji Inamura.

Hello,

Could you please run the command:

$ ./fastboot devices

Does it output something?

It should output the device connected.

Regards,

Aldo.

Hello,

thank you for your support.

> Does it output something?

fastboot command outputted following message.

xxxxxxxxxxxxxxxx fastboot

above strings "xxxxxxxxxxxxxxxx" are serial number,

so i think fastboot command can communicate the board physically .

Hello,

I notice that you're using user as your build type this could be causing your issue since it is a production-ready image, no debug, so could you please try changing your build to userdebug or eng:

$ lunch evk_8mm-user-debug or $ lunch evk_8mm-eng

Hope this helps,

Regards,

Aldo.
