[GitHub] [incubator-nuttx] michi-jung opened a new pull request #5470: STM32U5 Architecture Support
michi-jung opened a new pull request #5470:
URL: https://github.com/apache/incubator-nuttx/pull/5470
## Summary
This is my current state of work on getting NuttX to run on STM32U5. I am especially interested in the TrustZone support of ARMV8-M. The 'nsh' configuration of the b-u585i-iot02a board runs fine as the non-secure companion to STMicroelectronics' port of TrustedFirmware-M.
## Impact
All code is in new subdirectories and should not have any impact on current configurations.
## Testing
I am running a basic 'nsh' configuration fine as a companion to TrustedFirmware-M on B-U585I-IOT02A.

Ok, Do you have plan to run NuttX on the secure side too?

@michi-jung I am interesting that have you run NuttX on the secure side?

@xiaoxiang781216 Thanks for the approval. I have TrustedFirmware-M running on the secure side and NuttX on the non-secure side. If you are interested in more details you could have a look at STMicroelectronic's UM2851 document. Basically, I replaced the `TFM_Appli_NonSecure.bin` image with the `Nuttx.bin` image.

No, I do not plan to run NuttX on the secure side. The ARM Platform Security Architecture recommends to run the RTOS in the Non-secure state and run some less complex software (with a smaller attack surface) providing the trusted services in the secure state.
