Firmware CRC / Debugger
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....
Resolved! YMODEM for SBSFU safe enough?
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...
SBSFU - Improve boot time not working
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 ...
Resolved! AES_GCM Acceleration: Mismatch between Accelerator and MbedTLS & Header size forced to 1 by CubeMX
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...
