Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello,I have done a big mistake. I was testing a provisioning using the system bootloader. For that I have changed the provisioning batch files. As a result I have set the product state to closed, before the keys where loaded. Now I can not connect ...
I do have the document UM2262 which describes the SBSFU expansion package, but it only gives a fairly brief explanation of the prepareimage tool.
Hi Team,I hope this email finds you well. I am reaching out to inquire about documentation similar to UM2262 but specific to the STM32H5 microcontroller.We are currently working on a project that involves firmware encryption, decryption, and update p...
Hi All,I've got a question about the documentation and operation of the SBSFU partial image generation.The partial image feature of the image preparation tool is documented in the appendix of the getting started document here: https://www.st.com/reso...
Hi,I am trying to write a bootloader that implements secure boot on STM32U545 or 585. Now I work on the SBSFU Example from ST on the discovery board b-u585i-iot02a as a starting point.Questions: Can I use a bootloader based on the SBSFU_Boot from STM...
Hello, I am using the STSAFE-A110 connected to the ESP32C3 board. I referred to the service interface from this GitHub repository (https://github.com/kmwebnet/stsafe_esp32_test). I have matched the Host MAC key and cipher key exactly as in the exampl...
Hello,I am working on implementing secure firmware with OEMiRoT boot on the STM32H563. I have configured I2C1 and TIM1 as non-secure peripherals. While the TIM1 interrupt works as expected, I am encountering an issue where the I2C1 slave interrupt ha...
Hello, I hope you are doing well!I developed a project based on the STM32H573I-DK example with TrustZone. However, in the final board, I am using the STM32H573VI microcontroller. I migrated all the code to this microcontroller, made the necessary pin...
board: stm32U585 + stsafe-a110 before the stm32u585 enter the low power mode ,I want to set stsafe-a110 enter the low power consumpion mode. I can't find the methods to enter Hibernate
I was trying to test the capability of the STSAFE-A110 chip to store and verify a password, but it didn't work.StSafeA_PutAttribute() returned STSAFEA_UNSATISFIED_ACCESS_CONDITION.StSafeA_VerifyPassword() returned STSAFEA_ENTRY_NOT_FOUND.I'm not sure...
