I need to perform SFI on an STM32U599 MCU, so following the wiki article "SFI Step-by-step on STM32 boards" I prepared the firmware and programmed the HSM V2 smartcard.I'm sending the commandSTM32_Programmer_CLI -vb 1 -c port=SWD mode=HOTPLUG -sfi xx...
Hi,I am trying to replace mbedTLS library with Wolfcrypt library for crypto operations in SECoreBin project of SBSFU. I was able to replace SHA256 related APIs. But the bootloader is crashing when I try to initialize wolfssl ECC key object under SE_C...
Ok, well I'm going to answer my own question, Yes.This stems from an earlier conversation about doing CRC15 or CRC-15-CAN, where I had postulated that it probably could, and I then subsequently proof-of-concepted that idea, and then started pondering...
Hi @Jocelyn RICARD GreetingsWe have a query from our support team"known vulnerability in the STM32U5 series related to the JTAG lock when using RDP (Readout Protection) Level 2." Is it advisable to proceed with this implementation, or should we consi...
Working on setting RDP (read out protection) on STM32H750. We are using an external loader to be able to read from/write to external flash. The internal flash only contains a bootloader.1. Setting RDP to Level 1 doesn't prevent reading external flas...
Hello, My project is based on the STM32H753 chip.I Using the STM32CubeProgrammer and try to set the RDP level from 0 to 1, I get the error "Error: Expected value for Option Byte "RDP": 0xBB, found: 0xAA".I only enable the Secure Protection.How can I ...
Hi ST Team, Currently i am using STM32H523RCT6 mcu for one of my project. In this i want to set the read out protection of level 1. Currently i am using below sequence to set the read out protection of level 1 protection.. // Unl...
I am using STM32U585 and I stumbled upon the following problem:If a device is configured with TrustZone enabled (TZEN=1) there is different behavior in the following situations:1. SPI is configured without DMA and CPU is running non-secure code in pr...
Hello,I am using SBSFU on the STM32U5 microcontroller, and I have implemented a function to determine the cause of the system reset by reading the RCC register flags. However, every time I enter the function, it always returns an 'unknown reset' valu...
Hi,I am working with SBSFU on a STM32U575 microcontroller, and I want to use the __attribute__((section(‘.ram2’))) to place a variable in the secure SRAM2 memory section so that the variable can write to it. However, the secure SRAM2 memory is reset ...
