Questions about how Trusty OS runs on hardware development boards

yeyuan1 — Thu, 24 Feb 2022 01:27:19 GMT

Hello everyone

my board is i.MX8M Mini and system is Androidp9.0.0_2.3.0.

I can now compile an image of Android and run it successfully on the hardware development board.

I was also able to compile an image of Trusty OS - lk.bin. The bin file path is as follows, I think I compiled successfully。path of lk.bin

The current problem is that I don't know how to download lK.bin to the hardware development board. I don't know what to do with lK.bin.

I consulted the i.mx_android_security_user_guide document, but found nothing.

Is there any other documentation to support it? Or do you have any ideas that can guide me?

Best wishes to you.

Hello yeyuan.

Suppose that the network access is available for it. mobaXterm would be a good option.

1, connect you host to board, and then get the network information which assigned to it.

2, use ssh to remote to the board. there is convenient way to drag files.

The lk.bin that generated by trusty build named tee-imx8qx.bin is actually trusty os.

You might refer to 8.6.1 Initializing the secure storage for Trusty OS for how to enable security with it, and refer to 2.2 Trusty OS security recommendations for i.MX 8 SoC configuration.

Best regards

Hello Harvey

Thank you for your answer.

I'm using the mobaXterm tool， it is good.

'8.6.1 Initializing the secure storage for Trusty OS for how to enable security with it, and refer to 2.2 Trusty OS security recommendations for i.MX 8 SoC configuration.', May I ask which document is the content of the two chapters mentioned above?

I have read the two documents Android_User 's_guide and I.mx_android_security_user_guide, but have not found the same place as yours.

Best regards
