I am developing some products based on STM32F407/STM32F429. What I am trying to do is to protect my firmware that:simply dump the code from one chip's flash (to hex file) will not work in another chipmoderate reverse engineering should not be that ea...
Hello,I am designing a firmware for an IoT that needs to be able to be updated securely. I decided to use the X-CUBE-SBSFU package. From a crypto point of view, the requirements are that:The firmware update needs to be confidentialThe firmware update...
I use STM32H7xx_DFP in last version 2.8.0 and in Keil uVision. There is shown some wrong addresses on the CRC registries. So I repaired it in svd file and generate new SFR file for STM32H753. If you need repair CRC view, I can send the sfr file to th...
Hello,with a new never programmed stm32g031 chip I get different values for PCROP if the same chip is read with ST-LINK or with bootloader+UART.The CubeProgrammer version is 2.7.0Which is the reason for that?Thank you
We are working on one of the project there is a requirements to develop small adaptor card to support new external module with I2C interface (Current Host module support only SPI interface).We are looking for low cost basic Microcontroller from ST fo...
I am trying to build the 3 components that comprise the "2 Images" variant of the SBSFU v2.5 package. This requires building the following components: 2_Images_SECoreBin - 2_Images_SBSFU - 2_Images_UserApp The SBSFU package does not, however, c...
Hello all,I have developed a code for stm32f103, which works fine.During code execution, some device configuration data is Read & written into flash (works fine).But when i enable read out protection, the code doesn't work.My understanding is that wh...

I'm currently investigating SBSFU options for STM32 and it seems like the base package incorporates authentication of the firmware based on on digital signatures (ECDSA, edDSA etc.) but does not incorporate firmware encryption. I have an additional r...
Hello Dear Friends! I use STM32F439 MCU and it has AES encryption peripheral. I tried to encrypt data in the format of uint32_t and it encrypted data and I tested it successfully on online tools. However, I wanted to encrypt data in the format of cha...
