How to Build & Test OPTEE on iMX91 processor

KiranM7 — Fri, 18 Jul 2025 13:19:59 GMT

Hi,

I am trying to understand the OPTEE functionality. Requesting support on following:

1. OPTEE documentation/ tutorial w.r.t. iMX91

2. How to Build & Test OPTEE on iMX91 processor with YOCTO.

Currently I have a YOCTO base developed from -

repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-styhead -m imx-6.12.3-1.0.0_security-reference-design.xml

Please find below the list of files generated from it

Hi @KiranM7!

Thank you for contacting NXP Support!

OP-TEE is enabled by default in our BSP. While we currently do not have an official guide for running optee-test, you can refer to the official OP-TEE documentation for detailed instructions:

optee_test
