Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Is this the right way? if (FLASH_OB_GetRDP() != OB_RDP_LEVEL_2) { HAL_FLASH_Unlock(); // Unlock the flash memory HAL_FLASH_OB_Unlock(); // Unlock the option bytes *(__IO uint8_t*) OPTCR_BYTE1_ADDRESS = OB_RDP_LEVEL_2; // Set RDP2 HAL_FL...
Hi,I've developed a custom board and I want to leave an encrypted signature using the STSAFE-A110 chip. However, I'm coding my board in Python, and I'm having trouble figuring out how to interact with the chip. I found the "STSAFE-A complete set of A...
Hello,I would like to be able to debug the SBSFU application of the STM32U5 microcontroller series. What steps do I have to follow to be able to do it? Thanks in advance
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...
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...
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...
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 ...
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...
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.
