Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
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 ...
Hi there, I'm under mass production with yours STM32L051x8 device. I use the internal EEPROM to keep some data. Note that is not en emulation eeprom on flash, is just 512bytes on internal EEPROM. In addition, I protect my code with ReadOutProtection ...
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,Thanks for all of the help so far. Another question, this one regarding SFI process for the STM32U5 series. In AN4992 section 3.3.1 for STM32L/U/W series, it describes a secure bootloader that is split into 2 parts, one of which is responsible...
