TF-M 2.3.x and crypto HW acceleration support on STM32U5

[amstmsi]

Our team is looking to implement an application based on the upstream Trusted Firmware M (TF-M) framework (https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/) to take advantage of the latest security capabilities provided by the framework.    But we’ve found that with the latest TF-M LTS release, 2.3.x, support for the HW cryptographic acceleration peripherals of the STM32U5 has been removed, due to the migration from mbedTLS to TF-PSA-crypto library.

Are there any plans for STM to implement support for crypto HW acceleration for STM32U5 in TF-PSA-crypto and TF-M 2.3.x?

Hello ​@amstmsi ,

yes the implementation is ongoing. I don’t have any committed date but I would guess it will be available before end of the year

Best regards
