OPTEE on i.MX8MP

[Fabio Estevam]

Hi,

I'm trying to boot the imx8mp-evk board with Optee support.

TF-A v2.14
make -j12 CROSS_COMPILE=aarch64-linux-gnu- PLAT=imx8mp SPD=opteed bl31

Optee-OS 4.9.0
make -j12 CROSS_COMPILE=aarch64-linux-gnu- O=out/arm PLATFORM=imx-mx8mpevk

Then I copied the bl31.bin and tee.bin to the U-Boot directory:

Any ideas as to why Optee fails?

Does anyone have Optee working on imx8mp?

Thanks,
