Hello All,, I am using STSAFE-A110 with stm32f429zit6 for secure boot, I want sample code / library for the same. Also my another query is will I have to sign the firmware using openssl externally. can anyone provide me complete step to finish the s...
Hey guys, how are you?It's been a long time that i'm facing a issue with STM32WB CPU2, most of the times i just fix it without really knowing the cause of it. Basically what happens is after power-up CPU2 simply won't initialize on the first try. I h...
Hello all,I am working on a bare-metal implementation of the PKA engine using the STM32WBA55CG. I have managed to properly initialize both the RNG and the PKA engines, but I cannot seem to load the operands on the RAM. I am trying to implement the mo...
Hello,after being busy with some other stuff, we are finally back to face problems with secure bootloader integration.What we learned so far (our learnt points could be wrong and corrections would be greatly appreciated):ST provides a very nice Cube...
Hello ST,We are developing device and we want to provide free FW updates if some bugs occurre. Updates will be flashed via DFU - usb communication. Currently we are using STM32F411CEU6.Can you recommend best options for protecting the FW from being c...
Hello Community,i have followed the documentation on how to enable RDP-like product state flash protection in STM32H5 microcontrollers.https://community.st.com/t5/stm32-mcus/how-to-enable-rdp-like-product-state-flash-protection-in-stm32h5/ta-p/708082...
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...
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...
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...
