Hello everyone,My team and I are working with a custom board based on the STM32WB55RG. Due to limited pin availability, we need to use USB as a virtual COM port for serial communication. We successfully configured the USB Virtual COM and were able to...
Hello,I will use the STM32WL33CCV6 as a wM-Bus gateway and the STM32WBA50KG for BLE 5.4 communications.We will encrypt these links with AES key.1) For STM32WL33CCV6 and wM-Bus, AES-128-CBC and eventually CMAC authentification will be used. It will be...
I am conducting operational verification of the sample application of X-CUBE-SAFEA1 by connecting NUCLEO-L476RG and X-NUCLEO-SAFEA1B.I have some questions regarding the operation of the sample application "STSAFEA1_WRAP_UNWRAP".My questions are as fo...
Hello,I am trying to use the UART peripheral in the secure zone via interrupts in SBSFU for the STM32U575 microcontroller, but I am not receiving any data. I have used the same code for the non-secure region, and it correctly receives the first value...
Using STM32WB55, for the SBSFU 2 image bootloader ST provide a linker script for the user application. This works, but the user application itself can only be updated by uploading a new application from within the application using YMODEM, or exiting...
Hi allI'm working on a STM32WB55 nucleo boardI'm designing a simple Signing procedureAt beginning I've try that every thing ok by using a hard codded key and now I want to switch on a key kept secure in FUS zoneI've load 2 256 bits AES keys into FUS ...
Hello everyone, Security is a key requirement in my current project, and while researching security for embedded systems I came across STM32 TrustZone and Trusted Firmware‑M (TF‑M). I’m working with an STM32L5 series MCU (which supports both TrustZon...
Good morning, I am Paul Goulpié, technical expert at Smile ECS - integrator of open source embedded solutions. I am contacting you because I have some questions related to the secure boot solution (mcuboot).I am using the following evaluation board: ...
Good afternoon,we are facing issue with AES GCM Tag generated with STM32U585.In particular we compare the results generated by the microcontroller with the ones generated by an application developed with C#.This is the code running on the microcontro...
Hello dear friends,this is my first post and I need your help with an issue I have. I designed some devices based on STM32C031C6. I use an I2C command to jump to bootloader and I upload the new firmware via I2C also from a microcomputer using the stm...
