During the workshop itself, I had some problems with some of the example files not having correct access rights to allow the workshop changes to be made.We worked around that during the workshop.Now I have just come back to the STM32Cube IDE; it star...
HelloThe crypto HAL driver ( function CRYP_SetKey in file stm32wbxx_hal_cryp.c ) of the STM32WB accesses the key as "array of uint32_t" (lines 2919 etc): hcryp->Instance->KEYR3 = *(uint32_t *)(hcryp->Init.pKey); hcryp->Instance->KEYR2 = *...
I converted code from one of the example from sbsfu for stwinkt1 board.This converted example is for 2 image and working fine on serial port.As far as i get for 2 image example configuration will like,SBSFU s;ot+1 active slot + 1 DWL slot + swap area...
I have some code that removes a "secure area" on STM32H75x by so called "regression" from RDP level 1 to level 0, which causes full erase.(Actually this code is based on example very kindly provided by ST support) void EraseAll(void) { uint32_t fla...
I am trying to create a mechanism of verification where I sign a file on the PC save it to a disk on a key device and then verify it by the MCU after saving it to internal flash.The PC is doing the signing process and the MCU should only do the verif...
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 ...
