I’m using STM32WL5MOCH6STR and want to add STSAFE-A110 for security in a LoRaWAN application.I want to know:How to use STSAFE-A110 for authentication, key storage, encryption and secure boot & secure firmware update.Which software packages are needed...
Hello STM32 Community,I’ve successfully built a Zephyr RTOS blinky application for the NUCLEO-H533RE board. Flashing the zephyr.hex using west flash or STM32CubeProgrammer works perfectly — the LED blinks and the serial terminal prints the expected s...
Hi,I come to you about the key provisioning process for the iROT in the STM32H5.Using TrustedPackageCreator, the keys provided in the file STiROT_Config.xml for the Secure Boot (field <Authentication key>) are both the private and public keys of the ...
Hello,I'm using STM32F439 with LWIP, SNMPv3, and mbedTLS, without FreeRTOS. I've encountered a performance issue when using the hardware acceleration for AES and SHA1 provided by ST (aes_alt.c, sha1_alt.c).Specifically, when decoding SNMPv3 messages,...
Hi everyone,We’re developing an IoT node for agricultural applications and plan to make it compliant with certification requirements (CE, CRA, RED).We’re using the X-CUBE-AZURE package as our starting point and want to use TF-M (Trusted Firmware-M) f...
I’m working with a NUCLEO-H533RE board (STM32H5 series, TrustZone enabled) and using ST-LINK for debugging.Here is the issue:Debug Authentication succeeds (certificate-based).Immediately after, the tool disconnects and shows:Error: Unable to get core...
Hello,My device contains both a bootloader and an application. I’m currently trying to protect the bootloader using PCROP on the STM32G0B1.As a first approach, I attempted to configure PCROP using STM32CubeProgrammer. However, this failed — once PCR...
Hi ST team,I am using STM32U5G9 as secondary MCU. It has simple firmware upgrade feature. It would be reset by main MCU and enter system memory bootloader using Boot0 pin. The system memory bootloader would receive upgrade image (application) from ma...
Hi.During production, we use USB to test the board. Finally, the MCU is supposed to be password-protected against flash reads. Unfortunately, it turns out that as long as the USB cable is connected, it's impossible to program the OBK. Segger Device P...
Hi, I have a doubt. I made some changes in the secure bootloader to achieve certain functionality, but I am unsure whether the code in the secure bootloader is developed by ST (such as drivers or APIs), or if it is intended for user modifications. Sp...
