Hi rdrr,

We don't have a ready-to-go OPTEE design example for Agilex 5 right now, but it is on our roadmap. Depending on your timeline, this may be a project we can develop with your input.

hi rdrr​ rdrr,

  I'm aware that the Devs at Altera are looking at OP-TEE closely, with some internal progress already achieved. The release timelines are likely late this year, but reach out to us if you want to shape it to match your requirements.

thanks!
