Dear allI want to check flash integrity with CRC checksum – IAR workbench has built-in features to calculate and add the CRC to the firmware.Under STM32CubeIDE I use a post buildsrec_cat.exe firmware.bin -binary -stm32-l-e 0xEFFC -o firmware_withCRC....
Hi,I have seen, that for the bootloader with just one image, it is only possible to use the YMODEM with UART for updating the firmware with the SBSFU. Now what I'm am concerned about is, that the YMODEM seems not to be very error tolerant. So, what f...
Hi,When I have a look at the AN5056(https://www.st.com/resource/en/application_note/dm00414677-integration-guide-for-the-xcubesbsfu-stm32cube-expansion-package-stmicroelectronics.pdf), there is a possibility on page 39 to improve the boot time. That ...
Hi,I am currently trying out the AES Accelerator of the STM32WB55, using the HAL. It is working fine on its own, but I am unable to get matching results to MbedTLS. So Ciphertexts and Tags generated by the Accelerator are not matching those generated...
Hi,Please advise how to verify token generate by "psa_initial_attest_get_token".My test kit is B-U585I-IOT02A and test application is TFM.Thanks,QiZhang
Hi,I am facing untraceable issue with SBSFU. I integrated SBSFU features to our application running on device with 512kb flash. After downloading the firmware, during the swapping, it is throwing some abnormal errors while writing to addresses 0x0803...
Hello everyone,I have pretty uncommon question. I'm working on STM32WB with SBSFU, and I'm wondering, if it's possible to use non-secure boot with it? As far as I'm concerned, secure boot is enabled by default, but many security features can be disab...
Hello, I am new with NUCLEO STM32G4754 and trying the SBSFU examples (1 image). I can flash and launch the SBSFU but I can't load any user application (userapp.sfb)I use STM32 tools, Windows with the same result :I connect using Teraterm (on Windows)...
Hi,Device - STM32H7B3I-DKSBSFU base Project - STM32H7B3I-DK\Applications\2_Images_ExtFlashI are using a different flash chip than STM32H7B3I-DK has MX25LM51245G and I am using MX25L51245G1) I have implemented the flash driver and test with standalo...
