Re: [TF-M] PSA Certification without PS?

A quick information: Internal Trusted Storage is mandatory by PSA for isolation level 2 and 3.

Hello,

Most probably, we will port TFM to a platform with TZ and external flash, BUT without internal flash. Is it possible to certify it for PSA L1 & L2 & Dev API, without Internal Trusted Storage service and its API? Do you see any issue?

Thanks Andrej Butok
