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: [cid:image002.png@01DAEFC7.96FE4EB0]FATAL ERROR: HardFault Here is some context for the exception: EXC_RETURN (LR): 0xFFFFFFF1 Exception came from secure FW in handler mode. xPSR: 0x00000003 MSP: 0x31000B18 PSP: 0x31000BF8 MSP_NS: 0xFFFFFFFC PSP_NS: 0xFFFFFFFC Exception frame at: 0x31000B18 R0: 0x31000B60 R1: 0x00000000 R2: 0x0000001B R3: 0x00000002 R12: 0x00000000 LR: 0x38009EF7 PC: 0x3800AB02 xPSR: 0x6100000B Callee saved register state: R4: 0xFFFFFFF9 R5: 0x31000B60 R6: 0x00000002 R7: 0x00000002 R8: 0x38030F24 R9: 0x0000001B R10: 0x00000011 R11: 0x38030F11 CFSR: 0x00008200 BFSR: 0x00000082 BFAR: 0x00000004 MMFSR: 0x00000000 MMFAR: Not Valid UFSR: 0x00000000 HFSR: 0x40000000 SFSR: 0x00000000 SFAR: Not Valid

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
