Hello,I am programming with the STM32U575ZIT6 microcontroller, and I am trying to update the firmware in the secure zone. However, when I try to update the firmware in the secure zone, the function ret_arm=LOADER_FLASH_DEV_NAME.EraseSector(sector_add...
I am working to generate the CRC for the flash memory, During this I am facing hard fault when the CRC module tries to read from certain flash locations, to debug it I made a small loop which assigns the value of each 4 byte. I found that reading at ...
Hello,I am using the SBSFU application on the U575 microcontroller and have created my own program, which is stored in the secure area and accessed via NSC. I am trying to send data via ultrawideband, but the interrupt is not triggered. I have tested...
Hi I am working on SBSFU Application project from STM32U585 project. And I am trying to use mbed-crypto APIs like SHA512 APIs as below mbedtls_platform_setup(NULL);mbedtls_sha512_init(&sha512_context);mbedtls_sha512_starts(&sha512_context, 0); // 0 f...
Hi,We are going for mass production of our device and we are using STM32H563IIK6 chip. And We need JTAG need to be Locked.And in our production we are using Segger JLINK .Can you provide how to implement PRODUCT_STATE using Segger JLINK.
Hello,We are planning to integrate the STSAFE110 into our device, which runs on Ubuntu. Since we’ll be developing our own code to retrieve the unique ID, I wanted to ask if there is any reference manual or documentation available for this. I couldn’t...
In OEMiROT_BOOT project compilation, first we are checking if the is recognized or not. Before that "Project.eww" needs to be opened and then we are creating the Project.bin binary file under EWARM. So how to do that. My purpose is to perform OTA via...
Hi,I am working on the wiki "How to start STiRoT".Actually, my board in in CLOSE state and the DA returns the error "Debug Authentication failed" after Discovery (see below). The key and certificate used is the deafult ones.The connection through STL...
I am working with SAES on STM32U585. I am trying to make use of wrapping/unwrappinng my encryption key with hardware-secret key DHUK . This in the SAES initialization I am using hcryp.Instance = SAES; hcryp.Init.DataType = CRYP_BYTE_SWAP; hcryp.I...
Hi everyone,We’ve been using the XCUBE-SBSFU bootloader in our industrial-grade project and recently noticed that SBSFU is now labeled as a legacy bootloader. It seems the new recommended bootloader is based on MCUBoot. Additionally, I’ve come across...
