I'm trying to port the SBSFU to STM32H735. I started from the project for the NUCLEO-H753ZI.I get errors in sfu_fwimg_core.c on FW_INFO_TOT_LEN but where is this defined?A simple grep -r turns up nothing.Thanks!
We are evaluating if we can use the STM32WLE5, to interface to existing devices .A critical factor is the expected endianness of the data. I have seen no reference in the docs if this can be set, so I have provided an example message and would like t...
Hello,one question (or feature request):I try to use the STM32 crypto library (v1.3.1 software implementation) on STM32WB. I activated the RNG and CRC but the calculated results (encryption/decryption, cmac) are not ok. Are there other things to do?I...
Hello,I want to calculate the CRC (32 bit) of image at post build and insert it in a known location in the image.In order to do it I should perform the following steps:a) Definition of placeholder in linker script fileb) Post build steps: b.1) Ca...
HiI want to use the Cryptographic peripheral on the above nucleo board, in the following way.Serial message from embedded board-->H745 crypto engine-->wireless transmission-->Decrypt packet on remote x86 laptopAnd the reverse direction tooSo clearly ...
Hi!I'm triying to set the CRC-16-IBM: X16+X15+X2+1, but CUBEMx does not allow it. In fact, I cannot introduce any polynomial.Is it a CUBE issue? How can I introduce the CRC-16 IBM polynomial ?Thank you
HelloIn STM32 Crypto Library, there are function "AES_CMAC_Encrypt_Init", "AES_CMAC_Encrypt_Append" and "AES_CMAC_Encrypt_Finish" to calculate the authentication code of a plain text.How can this be done on STM32WB using the CRYP peripheral (HAL driv...

Hi i was wondering how i should go about implementing USB instead of UART to download the firmware in the SBSFU bootloader. I have successfully managed use USB in DFU mode to install a new firmware.
