Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
We currently utilize the STM32H7B0xB microcontroller, which offers 1.4 MBytes of RAM and 128KBytes of flash memory. While exploring the SBSFU examples found examples for running from external flash directly, I could not locate one that specifically d...
Greetings, supportTeamEnjoy your day. I'm working on the STM32U585 Series' firmware upgrade procedure. I have a development kit (B-U585I-IOT02A) for POC purposes. I'm using TFM-boot, TFM-Loader, and TFM-Application for firmware upgrades. I activated ...
Hello,I need a quick confirmation. Assuming I have correctly provisioned OEM1KEY and OEM2KEY and I don't use OTP memory, I will always be able to revert my STM32U585 chip from RDP level 2 to blank state (RDP level 0, erased Flash, TrustZone disabled)...
Hello,I am working on integrating SBSFU with the STM32F4 controller. The target controller is F429.I am trying to build an example project. It is a single image slot project which is developed for STM32F413H. I build the SE_Corebin project first and ...
Hello supportTeam,Enjoy your day.I'm developing a firmware upgrade function(Bootloader). STM32U585ZIT6 series controller was chosen by us for our product development, and B-U585I-IOT02A development kit was used for POC.A firmware update solution is g...
Hello supportTeam,Enjoy your day.I'm developing a firmware upgrade function. STM32U585ZIT6 series controller was chosen by us for our product development, and B-U585I-IOT02A development kit was used for POC.I'm searching for Firmware Upgrade Feature...
I thought this would be simple, open up the STMCubeProgrammer, connect to the programmed device, select RDP, select BB read protection (CC means the MCU can never be reprogrammed so no user-done code updates!!) and then Apply!But no, the board screen...
Hi, we have to use a secure bootloader for STM32U585.I have reading documentation about SFI and SBSFU and I am confusing.1) Is theresomewhere a porting of SBSFU on this device?We want to use a custom secureBootloader that only check update inside e...
Hello supportTeam,Have a good day.we are working on the STM32U585ZIT6Q controller. I turned on the trust zone option in this controller.I have a few questions about the priority of peripheral interrupts, which I explain below.1. What happens if an IS...
Hello,Im using STM32F723 and using the Cryptographic Library (https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Security:Getting_started_with_the_Cryptographic_Library).When testing basic cmox_aead_encrypt and cmox_aead_decrypt example it works fine.B...
