Hi Poppy,

The framework should not return PSA_ERROR_GENERIC_ERROR for a call to psa_connect.

The error might be returned from the SP2.

Could you double check if SP2 had been scheduled to run and received the connection request from SP1 correctly?

And had it handled the request as expected?

Best Regards,

Kevin

Subject: [TF-M] psa_connect() return invalid connect handle error

Hi experts,

We are developing a demo based on TF-M framework, and we also developed an application RoT partition SP1 and a PSA RoT partition SP2.

The secure partition SP1 needs calling a SP2's service during SP1's init(), when the SP1_init() calls a SP2 service, as the SP2 partition hasn't
been inited, the SP2_init() executes before handling requestS from SP1.


But the returned connect handle is an invalid handle, return PSA_ERROR_GENERIC_ERROR.

I am wondering why an invalid connect handle is returned? Any hints?








Best Regards,
Poppy Wu
