Dear community,I have been experimenting with secure boot on the STM32H573I-DK using the latest git checkout of STM32CubeH5 (see https://github.com/STMicroelectronics/STM32CubeH5).The STiROT and OEMiROT examples run fine out-of-the-box. However, when...

Hi,While using the STM32Cube_FW_H5_V1.1.1 repository to explore secure boot on the STM32H5, I saw that the configuration file to generate OEMiRoT_Data.obk is missing. As I want to use my own keys and certificates for the OEMiRoT example application, ...

Hi,I have been experimenting with secure boot on the STM32H573I-DK, but I can't perform a regression anymore.While adapting the example code (OEMiROT) to my own version, I am currently in the situation where the device is "provisioned" (0x2e), but I ...

Hi @CMYL ,I think I have found a possible solution. However, I cannot explain the problem currently.To summarize all above posts:Running the TrustZone examples on the STM32H573 DK results in a hard fault;The error seems to be consistent across differ...

As an experiment, I tried to use CubeMX for OEMiROT as described on https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_STM32CubeMX_OEMiRoT_Boot_path_on_STM32H573There it fails in step 8:When I press the black button, the board indeed resets...

By the way, @CMYL , I have tested the STiROT_Appli_TrustZone I mentioned in my previous post on Windows as well, and also there it does not work.After some more debugging, I found that there is a difference between:the code for a secure+nonsecure app...

Extending on the seemingly inaccessible stack address, could it be that the call to unsecure_sram3 does not behave as expected (if I understand the code correctly, then that function should "unsecure" the memory to be used by the nonsecure applicatio...

Hi,I have verified the correctness of the path of STM32CubeProgrammer. To confirm that, I set it to a non-existent path and then the provisioning script failed. For what it's worth, I'm using Linux. So instead of the *.bat files, I'm using the *.sh f...
