Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Assuming that the MCU has the Secure Services feature (Secure Boot), does the BOOT0 pin have any use? My understanding is that the application in the secure bootloader would decide its entry point rather than using the addresses specified by the BOOT...
I am using STM32L562E-DK board.I am using the SBSFU example. I want to use the ECDSA-256 cryptography scheme. When I am verifying private with key.c file it does not matchI have used following command to verify private.openssl ec -in root-ec-p256 -ou...
Hi,When the TZ is enabled, the STM32U5 and STM32L5 has different action when the RDP is configured level 0.5.STM32U5 don't have "Secure Area1" and "Secure Area 2" in the option bytes, but STM32L5 have.Please advise stm32u5 whether has plan to recover...
Hi,Follow the instruction in the README.md, I can compile and load the code into the kit, and the code is working fine.Please share me some information how to debug "TFM_Appli secure" and "TFM_Appli non secure" project?Thanks,QiZhang

Hello, I have a simple application running on STM32L55 Secure World, but I would like to debug it step by step using an IDE.I am able to debug using the Keil IDE, but it seems the TZEN bit is zero. It must be about the defaults state of the STM32L55 ...
Hi all,I’m trying to find out when the Boot Hardware Key (BHK) is exactly written and locked (using the B-U585I-IOT02A discovery kit).The reference manual (RM0456, page 1513) just says that it is „written by a secure code during boot“.So I modified a...
I am able to run "2-Image" sample application in NUCLEO-L073RZ board.I would like to use "1-image" application due to memory restriction.But example application for "1-image" is not provided for NUCLEO-L073RZ board.Could you please let me know the ch...
I am using STM32L562E-DK for my development. I have ported SBSFU for it. I want to add watchdog functionality to it. Currently, I am initializing the watchdog (window) from the application and feeding it from Freerto's task in the application.Now, I ...
Hello,I am trying to get familiar with X-CUBE-SBSFU. I am currently confused about the meaning of "-v, --version" flag for "prepareimage.py header" and "prepareimage.py pack" commands, e.g. from readme:python prepareimage.py pack -k OEM_KEY_COMPANY1...
