Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello everyone,I've spent a considerable amount of time trying to change the default AES and ECDSA (ECCKEY1) keys, but I can't figure out why it always results in a 'Fw header authentication error' during the firmware image update process.The project...
The documentation I have says the Ethernet calculation with 0x4C11DB7... but I don't get results matching what I get from any other calculator. To remove any endianess or mirroring questions I've tried 0x00000000 and 0x66666666 (e.g.). All calculat...
Moved from MPUs forum: STM32C0 is an MCU - not an MPU.Hi,I am not sure if STM32 cryptographic firmware library can run on STM32C071 because this microcontroller does not have embedded Crypto (Hardware) ? Thanks Gregory Saint-Jean
In the SBSFU reference code for the STM32H753ZI controller, I came across the following function:FLOW_CONTROL_CHECK(uFlowProtectValue, FLOW_CTRL_RUNTIME_PROTECT);This function compares whether the two values are the same. In my implementation for the...
Hello all,I have been working on a bare-metal implementation of the PKA engine in the STM32WBA55CG microcontroller using Rust. So far, I have been able to run modular addition and subtraction, modular exponentiation, arithmetic operations, ECC point ...
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: ...
Hello.With a STM32H563, i can change the product state to 0x17 (provisoring), reconnect with HotPlug,start provisoring with my OBK-File and change the production state to closed (0x72) without any problems.I don't use TrustZone.A full regression afte...
Porting SBSFU 2.6.2 to STM32G0B1CEU6 (512K FLASH and 144K RAM) based on Nucleo-G071RB example.See the history of my previous Solved: SBSFU 2.6.2 firmware swapping issue - STMicroelectronics CommunityAfter I solved the firmware swapping issue, I went ...
Hi Team,I've updated only the UserApp RAM region. I came across a post stating that SBSFU and the application are independent, so I followed that approach. However, after modifying the RAM region and uploading the sbsfu.bin file to the MCU, I get an ...
Hi,We are using an STM32U585 with the application running from external flash, on an octospi bus. We are also using external SRAM. The external memory architecture on our board is heavily influenced by the B-U585I-IOT02A design (same ports, slightly ...
