Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
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 ...
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 ST,I can't seem to get debugging to function when following the above named example on a nucleo-u385RG-Q using CubeIDE and CubeProgrammer. The guidance on the README is vague when it needs to be clear - for starters what is the 'offset of the firm...
I am currently working with SBSFU on the STM32H743ZIT6 series and have implemented several modifications to its core functionality. I would like to clarify the potential impact of these changes:Modification to SBSFU FunctionalityI have altered the d...
Hello, In order to comply in advance with the incoming CRA regulation, we would like to have RDP1 enabled on our U575. In order to do this the fw, in the early stages of the initialization procedure, will have to check if it's in RDP0 by reading the ...
Hi,In paragraph 1.2 “Launch the provisioning script” I read that:Launch one of the provided scripts depending on your IDE:For EWARM or MDK-ARM: launch the provisioning.bat script.For STM32CubeIDE: launch the provisioning.sh script.I have Windows and ...
Hello,STM32H533 It seems that Option Bytes are not programmed during SFI ??To keep things simple, I changed BOR_LEV, but after SFI, the BOR_LEV was not programmed.Also, I would like to move product state to closed (0x72), that that is also not progra...
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...
Hello everyone, I am looking into using HDPL and would like to know if there is any way to communicate from HDPL3 to HDPL2.From what I have understood so far, I need to perform a reset to return to level 2 and execute whatever I need. However, I woul...
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...
