Hey All,


Have some questions to ask you about the TrustZone, TFM uses cases and secure debug :


      1- If I understood correctly, we can't debug once secure boot is enabled, therefore we can't talk about secure debug too ?

      2- I don't know how secure boot ROM it works because i don't have access, but in this sense can you confirm that the ROM code doesn't enable TrustZone for SB security features ?

      3- Last question but not least, in your SDK last release you provide TFM implementation ? Can you please explain the perspectives of this implem and the eventual use cases ? 

            I mean today your SB doesn't relies to PSA-RoT so i can't understand if your are planing to integer in SB or others appli ?



Thank you in advance


Best regards
