iMX8M Plus Trusty OS problem

domenicoacri — Fri, 10 May 2024 12:36:54 GMT

Hi,

I'm working on a custom board with iMX8M Plus processor with 4GB of RAM.

I'm trying to enable the Trusty OS to access the RPMB secure storage.

I downloaded the trusty software:

repo init -u https://github.com/nxp-imx/imx-manifest.git -b imx-android-12 -m imx-trusty-android-12.0.0_1.0.0_github.xml

repo sync

source trusty/vendor/google/aosp/scripts/envsetup.sh

make -j32 imx8mp

cp build-imx8mp/lk.bin ../android_build/vendor/nxp/fsl-proprietary/uboot-firmware/imx8m/tee-imx8mp.bin

when I boot the Trusty bootloader, I get the following error in attached.

What could be the problem?

If you need other info, let me know.

Hello,

You would need to follow the instructions on the Android User’s Guide (link below, as this is the latest version, if you want to look for it at a later date you may need to download the documentation package for this BSP)

https://www.nxp.com/docs/en/user-guide/ANDROID_USERS_GUIDE.pdf

You can find the instructions to do that in our release user guide. Once you have fused, you cannot change it. So be careful to do that.

regards

Hi,

Thanks a lot for the answer.

I'm using Android 12. Why do I have to use the Android 14 version?

Anyway, I downloaded the Trusty OS for Android 14.

I compiled and copied the "lk.bin" file.

Now I get several errors in attachment.

What could it be?

Hi,

sorry but I did not understand.

Could you be more specific?

What would be missing from kernel?

In the log file, we are in the uboot.

Hello,

Something wrong in the kernel, that's way uboot does not passed to kernel.

Hi,

problem solved.

SPL_CRYPTO_SUPPORT was missing from uboot defconfig,

and I used ATF v.2.6 to support the module with 4GB of RAM.

It wasn't a kernel problem.

Thanks for the support.
