Porting NUCLEO-H753ZI/Applications/1_Image to STM32H753.This is running on STM32H753I-EVAL2 board.The bootload can be done in 2 steps (download SBSFU.bin, then download UserApp.bin) or in 1 step (download SBSFU_UserApp.bin). The behavior is the same:...
Hi, I am coding on the NUCLEO H753ZI board with the pack for embedded cryptography (x-cube-cryptolib-3.1.2). While this folder provides example with hardcoded keys, it does not provide an example with keys imported from a file. Typically, I would lik...
Hello togetherI use the following library to create random numbers:- LibraryThe sample project runs on my NUCLEO-144 H743ZI. The problem is that the same byte array (RandomString) is generated at every time. *****************************************...
In the code below I have AES GCM correctly decrypting data using the Cryptolib. I am trying to decrypt the same data using the HAL_CRYP_AES_XXXX functions and it isn't working.Key is 32 bytes. iv is 12 bytes. header data (aad) is 3 bytes. message...
Hello All,We have designed a Custom Board with STM32F777 MCU chip and are using Atollic Truestudio with ST Micro's CubeMX for development.I have implemented a USB boot loader for the same hardware which is working fine with the Custom Board.Now i wan...
Hi,I requested a download access to X-CUBE-SBSFU firmware about two weeks ago but I didn't get a reply yet. Is there something else I should do ?
Main is entered,(for testing I enable the GPIO and turn on an LED to validate that cpu execution has entered main() --- then I set up the PLL, and GPIO - then test if the MCU has option byte set for Level 1 - if not I set it.I reset the device and it...
Hi,Upgrading to version 2.2.0 i get this error using the option " --mergesbsfu" (Add a binary header and a sbsfu segment to an elf file):arm-none-eabi-gcc -o "STM32F769I-Discovery_AWS.elf" @"objects.list" -mcpu=cortex-m7 -T"../STM32F769NIHx_FLASH.l...
I am using multiple MCUs: STM32F733, STM32L433, STM32L443.In STM32CubeExpansion_Crypto_V3.1.0 I am using the software AES CTR encryption (Inc/AES/CTR/aes_ctr.h). I use AES_CTR_Encrypt_Init / AES_CTR_Encrypt_Append / AES_CTR_Encrypt_Finish methods. Th...
