Hi Andrej,

Thanks a lot! I will compare it with the one currently used in Profile Small to see if anything more can be saved.

Best regards, Hu Ziji

Hi David,

I have attached the Mbed-Crypto configuration file, which enables only minimum set of crypto algorithms required to pass the current TFM regression tests. It saves us about 30KB of ROM if to compare to the default TFM settings. Hope, it can be useful for others.

Regards, Andrej Butok

Hi all,

Could you please help review the latest design document of TF-M Profile Small (previously named as Profile 1)? TF-M Profile Small provides a predefined list of features with small memory footprint, on ultra-constrained device.

Major changes since last version:

* Renamed as Profile Small to avoid confusing readers with other similar terms. The other profiles will be named as Profile Medium and Profile Large. * Enable symmetric key algorithms based Initial Attestation.

Please help review the document on https://review.trustedfirmware.org/c/trusted-firmware-m/+/3598https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.trustedfirmware.org%2Fc%2Ftrusted-firmware-m%2F%2B%2F3598&data=02%7C01%7Candrey.butok%40nxp.com%7Ca64c05df22984e9b1d3108d7cfbdc016%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C637206286188566523&sdata=Z2Z2%2FWPsEHdo1dg6E%2FSXhNQSBACqcuFntqOuPoPHfr0%3D&reserved=0 for more details.

The corresponding implementation patch set is also updated on https://review.trustedfirmware.org/q/topic:%22profile-s-config%22+(status:op...)https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.trustedfirmware.org%2Fq%2Ftopic%3A%2522profile-s-config%2522%2B(status%3Aopen%2520OR%2520status%3Amerged)&data=02%7C01%7Candrey.butok%40nxp.com%7Ca64c05df22984e9b1d3108d7cfbdc016%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C637206286188566523&sdata=txOz6KHUF1jqgZPxDGfPnajghyTSDYmZlJd00IFAMi0%3D&reserved=0.

Hi all,

As we discussed in Tech Forum yesterday, we proposed the TF-M Profile 1 design document on https://review.trustedfirmware.org/c/trusted-firmware-m/+/3598https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.trustedfirmware.org%2Fc%2Ftrusted-firmware-m%2F%2B%2F3598&data=02%7C01%7Candrey.butok%40nxp.com%7Ca64c05df22984e9b1d3108d7cfbdc016%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C637206286188576518&sdata=jCQKLpVDxcInH2gQGP5ggsn20m3tmtXAjj6ex9h1ZkI%3D&reserved=0.
