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...
I was looking over the example projects that come with CryptoLib v4.0 in the package en.STM32CubeExpansion_Crypto_v4.0.1 for examples related to X.509 certificate handling and was not able to find anything in that regard. I wanted to confirm whether ...
I couldn't find any clear explanation for the term loader on an5056 and um2262.Maybe it is so obvious for others but unfortunately not for me:\ So here is my questions regarding loader and appreciate you helping me understand it well.What is the load...
Hi, I want to port SBSFU to my project which was written for the STM32F756VGT microcontroller by Keil.So I have some questions regarding this situation.At first, I took the `STM32F769I-Discovery` example of SBSFU as a base project that I need to make...
