About the future of TF-M with Zephyr

Hello,

Will it eventually replace SPM and will the libraries be updated to support it?

 Yes, it will replace SPM in the future.

Also, speaking about FOTA, is there any useful implementation for FOTA updates using TF-M with Zephyr ?

 You can try following this blog post.  It should be possible in theory, but you can try to run it and see if there are any issues.

Hi Hakon, thanks for your answer.

So, from my understanding, Nordic will slowly transition from SPM to TF-M. Is the transition going to be transparent (to the best of what's possible of course) regarding the libraries that already implement SPM by defaults like the FOTA library for example?

Best regards,

Farès

 Yes, you can follow everything on the TF-M repo on github. For more information you should contact the RSM.
