Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I have a question regarding the use of STM32F4 devices in IEC 61508 SIL2/SIL3 applications. The STM32 Safety Library documentation indicates that STM32 devices can be used in SIL2/SIL3 applications. However, I could not find an explicit Hardware Syst...
Hi @Jocelyn RICARD,GreetingsFor certifying with PCI PTS 7, the controller STM32U585 needs to be certified under the NIST Tool 800-22. Attaching the relevant guidance sectionAs per AN4230, STM32U585 has certificate for SP800-90B. For the NIST SP800-22...
The issue feels really simple, and it's easy to do on N6. At the core, I am running out of MPU regions as there are only 8 available. So it would be nice to have a small chunk of SRAM, where privileged code can share data with unprivileged code. Say ...
HI am a firmware engineer working on industrial power supply products. Our device needs to comply with IEC 62443 industrial cybersecurity standards (target SL2/SL3).We plan to adopt a dual-MCU architecture for this project:STM32G4: Responsible for re...
Hi, I have a NUCLEO-U3C5ZI-Q board, and I'm trying to follow the DUA_USER attestation process. I noticed that the existing Root CA certificates like here https://github.com/STMicroelectronics/STM32CubeU3/blob/main/Utilities/Certificates/ do not ver...
Test bed:- Nucleo-H503 & Nucleo-H533- Few WeAct H523 connected via Waveshare STLink v2 mini (4 wires only)- my own H503 based controller connected via cheap STLink v2 clones (4 wires only)- I am using STM32_Programmer_CLI v2.21.0 / Ubuntu 24.04 LTSId...
this thread is split from this thread hello Last question, I just saw the example but it's not for the STM32H755ZI-Q series, are the examples still compatible with this STM32H755 series? Thanks
Hello Team,Good Day !After Cloneed our two version of Hardware ( STM32F3 Series based ) by compititor , we are now more focused on Hardware Security aspects.Can you Pls Suggest which STM32 MCU is the MOST Secure among all available MCU ? Considering ...
I'm looking for a working example of how to program the OTP memory on the STM32H573.I am looking to program with TrustZone enabled, from secure mode. I'm using STM32Cube_FW_H5_v1.4.0, and am not in a good position to move to v1.5.0. Any working exa...
I have a STM32U585 (edit: ...VIT6, so not the one where this doesn't work due to errata) product with Trustzone enabled, Bootlock disabled and RDP level 0.I want to bring this into ST bootloader mode from software (for easy Firmware change via USB).T...
