In the code it says the following:/** * @brief This function writes a data buffer in flash (data are 32-bit aligned). * @note After writing data buffer, the flash content is checked. * @param pFlashStatus: FLASH_StatusTypeDef * @param pD...
I started a new project, and my security requirement states that user authentication is required when updating firmware.I wonder if there's a feature for this, and if not, can the bootload side be modified to meet this requirement?I searched and foun...
IAR would fill unused flash and optionally append a crc to aid with the integrity check some of us need to do for regulatory compliance But since IAR's been replaced what provisions are in Atollic to fill unused flash and optionally append a crc? Is ...
I wants to encrypt 8bits of data using AES256 Security with STM32L442KC . And sending Encrypted data through UART. I am confused in code that code is correct or not....please let me know any correction in this code. I am using Atolic true studio.u...
Need to protect data access through j-tag, but need to program flash through inbuilt boot loader
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...
