HelloI'm having trouble calculating crc. I am using STM32F401 with cube ide. The correct crc occurs on crccalc.com. But I couldn't run CRC-8 with MCU. I have looked at the examples, but when I try it gives different results. Can you provide a worki...
I am using STM32H747BI MCU and I have one project to write the data to flash memory. I am using core 7 to write the data to flash. While writing, I have to encrypt the data. So I requested cryptographic library software expansion from STM32 and they ...
I am exploring the security feature of STM32WL55JC via Applications/BFU_1_Slot using latest firmware STM32Cube_FW_WL_V1.1.0I am not sure what I am doing wrong and I have followed youtube and readme.txt. I was able to compile as below and upload STM32...
Is there any configuration we need to modify in prepareimage.py to overcome this error "ERROR: overlapped zone is not empty" or any other configuration?Below is output.txt file.python /Users/username/Downloads/STM32Cube_FW_WL_V1.1.0/Middlewares/ST/ST...
Hello!I have a problem with STM32L496RG booting from flash after activating readout protection level 1. The issue is that MCU seems to get stuck in system bootloader code. The only way to get it to boot from main flash is to apply power on reset.Accr...
Hello guys,I was setting up my STM32CubeIDE to use the SBSFU sample projets. I'm facing a issue with SECore engine, more specific the postbuild.sh script.When i compile SE, i get the following message:ln: failed to create symbolic link '../../postbui...
Hi everyone,I am using STM32F469/STM32F479 and want to integrate SBSFU with an SPI flash. Basically the active image is in MCU's 1 Mbytes flash and downloaded image is in the external flash. There are several questions I would like to know before I s...
Hello comrades,I've downloaded the SBSFU package, but there is no example for the STM32H747, moreover, I couldn't find an example for dual-core MCU (H755 or H747, etc.).I've tried to make some changes to the NUCLEO-H753ZI project within the downloade...
Hello everyone!I am testing my own firmware with the sbsfu bootloader (stm32h723). I have the problem that when the MCU is trying to set up the ethernet the board will die.The ETH region is protected by MPU and before enabling it in my app I disable...
Hi,I have download the newest version SBSFU v2.4.0.From the readme.txt, I compile the SBSFU project NUCLEO-G071RB 1_Image_SBSFU with the MINICOM_YMODEM switch enabled (app_sfu.h).But send the user encrypted firmware file UserApp.sfb always failed.How...
