Resolved! Clock change in the sbsfu application
Hello,I am using the stm32u5 SBSFU application and I am trying to implement my own 64 MHz clock. But when I change it from 160 Mhz to 64 Mhz the application does not work. Can the SBSFU clock work with less than 160 MHz or does it have to work only w...
Resolved! 32F417 and RDP2: OTP (512 bytes) and SRAM execution
Thissuggests that one cannot execute code from SRAM. Is that really correct?Also there is ambiguity on whether the OTP area (512 bytes plus the control block) is readable in RDP2. Why say "512 bytes" and not just all-OTP?The OTP area must remain usab...
STM32H563 Debug Authentication
Hello, I have a ARM Keil MDK project with STM32H563ZI and want to protect it against readout. So I want to use the Debug Authentication. The trustzone is not activated. The first time programming is done over UART and then over USB by an own tool and...

STM32U585xx SBSFU source code examples do not build properly.Nice to meet you.If you download and check the en.stm32cubeu5-v1-6-0.zip file (including patch), it contains an example for STM32U585 SBSFU.If you try to build the 'SBSFU' example for 'B-U5...
STM32F030K6 Core is Locked
I have 2 x SMT Electric Feeders (Same Model --- HGWC Yamaha YMH-EF8-000 8mm) with STM32F030K6 MCU that are having issues with Core/CPU lock up. NOTE: I know that when the STM32F030K6 chip is configured for either RDP Level 1 (Read Protection) or RDP ...
STM32H5_RHUK
Hi Team,I am seeking information regarding key storage in ITS memory. Specifically, I would like to know if ST provides any PSA Secure Storage API that automatically stores keys encrypted with RHUK to ITS memory. Additionally, I am interested in unde...
SFI Process
Hi Team,Am using STM32H573I-DK boardCan i get any document or explanation that how SFI is processing and what are the keys involved in encryption and authentication.I already referred AN4992 and wiki pages but the process is not so clear.
Resolved! Nucleo F439ZI AES in GCM Mode Accelerator Struggles
Hi Everyone! I am trying to understand why I cannot get the result of the AES in GCM mode HAL_CRYP_Encrypt on the F439ZI board to match the AES in GCM result anywhere else. I am using Python's pycryptodome library for result comparison. I have previ...
Secure Boot on STM32C031 Family
Hello ST Community,Can we apply Secure Boot on the STM32C031 family? I didn't find anything on the documentation. If not, what are the product series where we can apply Secure Boot?Thank you.
