hello ST Community,I'm trying to protect sector 0 of the flash drive from mass erasure using the PCCOP Protection option on the NUCLEO-H755ZI-Q.After tinkering around a bit to understand its functions, I can no longer reset its protection to its defa...
Hello,I'm currently integrating the SBSFU 2.8 for one of our board, that use a STM32H753, with a dual-slot configuration.I'm adapting the example for the STM32H753ZI. For now, this mostly involves modifying the USART (use the 6 instead of the 3).I am...
Hello, I've recently managed to modify the SBSFU example for the STM32F413H-Discovery board and adapt it for my STM32F419 mcu, building it and executing it successfully.Now the issue is, i need to modify the loading mode from serial ymodem to downloa...
Hi everyone,I’m currently experimenting with the GPIO_IOToggle_TrustZone example using STM32 TrustZone.When I build and flash both the Secure and NonSecure firmware, everything works correctly: the LED toggles as expected, so the interaction between ...
Hello,long time lurker, now with an issue that I would like to solve. I developed a firmware that runs standalone without issue. I would like to use the secure manager on my STM32H573VI microcontroller.I followed the procedures at this link: https://...
Hi,I am working with the OEMiRoT reference project (STM32U385) and I need to configure a single Secure application image without TrustZone isolation (S-only application), while still keeping the Secure Data Image enabled.From flash_layout.h, I see t...
I am a user of the NUCLEO-N657X0-Q board.I would like to use Keil MDK RTX5 RTOS together with Root of Trust.My development environment is as follows:1> Development tool: Keil uVision V5.422> Example source: STM32Cube\Repository\STM32Cube_FW_N6_V1.2.0...
Hello ST Community, I am working with an STM32U585 custom board and I would like to clarify the supported and recommended workflow for flashing TrustZone‑enabled firmware with SBSFU using USB DFU via STM32CubeProgrammer. Hardware / Software Setup MC...
Hi,On a custom board I get the following message: Unable to detect DBGMCU Mailbox STwhen i run regression.bat.I did several test (provisionning, regression) before and i didn't notice any issuesDA with password and TZ disabledA program is running on ...
and how will the information be made available for non-EU residents ?
