STM32U585 RTOS - Threadx - PSA certification

[Siva1]

Hello team,

Greetings!

We have selected Trust zone MCU STM32U585ZIT6Q (U5 series) for our product (EV charger) development.

We planned to use STM32 inbuilt 'Threadx' OS as RTOS for our product FW development. Could you confirm, is this PSA certified? 

Also please confirm, can we select/use FreeRtos (if PSA certified) for Trust Zone enabled Secure & Non secure FW project development with STM32CubeIDE?

Thanks in advance.

Regards,

Siva
