Hello,I am working STM32u575 Nucleo board. I want to use secure flash to store secure data and to use it I need to enable TrusZone. Is there a way we can program option bytes with TZEN =1 without using STM32programmer?Regards,Shafi
Dear Sir/Madam We are using STM32U585AII6Q MCU part in one of our projects. We encountered a problem with Flash read protection and no longer able to flash the MCU. Below is the reference screenshot from the error. We also tried few methods defined ...
I am working on STM32U575 to write and read from Secure flash. I referred STM32Cube_FW_U5_V1.4.0\Projects\NUCLEO-U575ZI-Q\Examples\FLASH\FLASH_EraseProgram_TrustZone\but I was facing following issueCan you please help me resolving it. Do we have an...
Hello,I am working with SBSFU on a STM32U575 microcontroller and have written a function to check the cause of the system reset by reading the flags from the RCC registers using __HAL_RCC_GET_FLAG. However, the issue is that none of the RCC register ...
Hello. I am experimenting with securing a STM32H503 using password authentication, which will ultimately be an automated process.I created a simple password for testing and created the password hash in board_password.bin and da_password.bin(just for...
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...
