I am using atolic truestudio 9.3 . myplaintext is a[1]={97}; uint8_t ciphertext [32]; my code is below, uint32_t retval=HAL_CRYP_AESECB_Encrypt(&hcryp, plaintext, 8, ciphertext, 5); if(retval==0) { HAL_UART_Transmit(&huart1,(uint8_t *)...
Hi,I'm in the process of implementing a HTTP server in SBSFU where I can upload an update file from a webpage. I've based my work on the code in sfu_loader.c, specifically the function SFU_COM_YMODEM_DataPktRxCpltCallback() and I try to follow the sa...
Need help on the secure programming support for STM32H753V MCU, OTA using hardware secure chip ATECC608A. Any example code or procedure would be a great help. Thank you.
Does X-CUBE-SBSFU support the external flash on the SPI for the secure boot and secure firmware updates ? If yes could you please provide more details if there is any reference boards which has this support. Thanks in Advance,Best Regards,Gowda
I have a problem with ECC signature verifiacation using STM32 crypto library example projects.I'm using ECC based on P-256.What I do:Start a firmware crypto example project - ECC/KeyGen_Sign_Verif - generate public and private keys, sign simple messa...
srec_cat.exe has a flag -STM32_Little_Endian described in the srec_cat manual as "These filters many be use to generate the CRC used by the hardware CRC unit on the STM32 series of ARM MPUs.". I can successfully append a CRC to my firmware file using...
We are using a STM32H7 microcontroller for our project ans would like to use the HW CRC embedded in the Flash module.We are designing a custom bootloader that will calculate the CRC and then write it in a reserved section of the flash. Since the devi...
Hi,I have a general question regarding CRC32 for data read from flash. For example I am reading 2048 bytes of data total 512 bytes chunk each time. My question isdoes it make any difference if I check CRC32 for every 512 bytes read or after read of 2...
Posted on January 08, 2018 at 10:21 Am I correct that readout protection has a major issue and is not working at all? Are all STM32s affected? Any comments on this from ST? See here: https://www.aisec.fraunhofer.de/en/FirmwareProtection.html ...
Hello,I am trying to decrypt some data on the L5. The data below can be fed directly into a python crypto library and get a valid result. I am trying to understand the 32-bit alignment requirements of the L5 as well as any possible byte swapping ne...
