Adding David from our platform integration team.

Which platform are you using to integrate the new peripheral? Can you access it before tfm_core_init() is called? This looks like that peripheral is not configured correctly for S access, letting David to expand on this. 

Thanks, 
Antonio

Subject: RE: [Technical Loop] PSA Crypto API with PUFcc on the TF-M platform
 

Hi all,

 

I am working on integrating our IP(PUFcc) into TF-Mv2.1.0, with the PUFcc located at address 0x51700000.

The PUFcc can be access on bl2 stage, however, it cannot be access on booting tf-m stage.

The exception log as below:

Could you provide any suggestions on this issue?

HI Andy,

 

Great to hear good news.

I will be in annual leave from tomorrow, Aug 1st, but Antonio (coped) could help you and can redirect the possible questions to appropriate team members.

With the occasion, I would appreciate if your team evaluates and follows TF-M documentation and gives us feedback on possible confusion or missing information.

 

Best regards,

Anton

#Set a new mail loop

Hi Anton,


We set a kick-off meeting of "PSA Crypto API with PUFcc on the TF-M platform" this week. 

·                TF-M v2.1.0

·                PSA Crypto API - v1.2.1

·                PSA Certified APIs Architecture Test Suite - v1.6

·                MPS3 with AN552

Randy, Victor, and Neil are members of this project. 

We would have many issues when developing that need your help to solve it.

Please feel free to add your teams. Let's make the project successful. 

Thank you very much.

 

 

Have a Nice Day,
Andy
