Hi,I have read datasheet of STM32F103VCT6, it does not mention anything about code read out protection. Does STM32F103VCT6 has this function? (a security function to protect STM32F103VCT6 from reverse engineering)Thank youDavid Kean
We managed to successfully run TFM_SBSFU example for the IOT02A board. We are using latest STM32Cube_FW_U5_V1.2.0.The problem is that we do not have access to PSRAM from NonSecure application when in memory mapped mode.We implemented PSRAM init by im...
Reference: STM32CubeExpansion_Crypto_V4..1.0, MCU: STM32G474REThe cmox_ecdsa_verify(...) function is failing with a fault code of 0x6c706, which is not contained within cmox_ecc_retvals.h header file. All arguments to the cmox_ecdsa_verify(...) funct...
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...
