Hi,I'm currently exploring the solutions to develop a bootloader on a STM32U535. I'm looking into the MCUBoot based examples provided by ST : SBSFU projects.After some investigations, I noticed that the SBSFU_Boot memory footprint was ~80ko and the S...
Hello,I generated an SFI image for STM32U585 based on my application. here is the details:Firmware information:SFI image details:However, when I try to install this image, it fails with the error:15:12:04:987 : PROGRAMMING OPTION BYTES AREA ... 15:...
I am new to SBSFU. I picked the NUCLEO-H753ZI project to try on a board with STM32H743. Everything seems to be running fine but ONLY when the SWAP_BANK is unchecked at startup. When it is checked before flashing, the board doesn't run as it was progr...
Hi,I'm currently developing a custom application which provisions and regresses an STM32H563, using the NUCLEO-H563ZI board for development.The CubeProgrammer CLI commands I'm executing are based on the bash scripts generated by CubeMX. Since I start...
Hi!I'm succesfully using SBSFU 2.6.2 on a STM32G474 with SECBOOT_ECCDSA_WITHOUT_ENCRYPT_SHA256.Now in another project I wanted to use the same SBSFU configuration on a STM32G0B0 but as this MCU is much less performant I switched to SECBOOT_AES128_GCM...
As for STM32H563 MCU, will it result in a system reset after executing the function HAL_FLASH_OB_Launch? From my experiment, before executing HAL_FLASH_OB_Launch, I can read data from MCU via I2C while all returned data become 0xFF(i.e. invalid data)...
Hi, I planned of implementing this library in a new STM32G4 application. I have no RTOS, and I need to make cryptographic functions calls from both main loop and interrupts. So, instead of wasting time in building a thread-safe scheduling mechanism ...
Hi,I'm trying to get a bit of an understanding of how the HSM is used in real world environments. The documentation I've found so far suggests that once the maximum number of installs for a card has been reached, the card is essentially dead and a n...
Hi, I have successfully managed to test the 1 image example of SBSFU on the STM32WB55. I wanted to try the 2 image example, but have found that the SBSFU application seems to get stuck in a boot loop, and does not advertise BLE. I have tried tying PA...
Hi,I have downloaded the STSW-SAFEA1-MW software. Error occurs when extracting the zip file. Please help. Thanks.
