My controller is STM32L462. I need to compute CRC16 for Modbus application. There is CRC initialization function:void MX_CRC_Init_CRC16(void) { hcrc.Instance = CRC; hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_DISABLE; hcrc.Init.DefaultI...
Hi,My STM32H735G-DK is having issues.When I try to flash a known good firmware, I get the following:command: STM32_Programmer_CLI -c port=SWD freq=4000 mode=UR --erase all -d build/stm32h735.bin 0x08000000 -v --start 0x08000000-----------------------...
Hi,Im looking for encryp using internal AES peripheral that the STM32G0 has.I need touse "AES128-CMAC" but i dont found the option in HAL libraries to set "hcryp.Init.Algorithm=XXX" and "defgroup CRYP_Algorithm_Mode CRYP Algorithm Mode" library optio...
Hello, Is it possible to custom the header of a firmware for SBSFU ? I want to add 2 variables but it's not working. I have authentification failure. But I don't change the size and position in the structure because I used the "reserved" bytes. (the...
I'm trying to compute the ECDH shared secret by multiplying local private key and other party public key using HAL_PKA_ECCMul. For some reason it is not working. I'm using curve secp256r1. But I'm able to use HAL_PKA_ECCMul to generate public key by ...
Hello supportTeam,Have a nice day.I am working on B-U585I-IOT02A development kit and i tried merge our application with SBSFU_Boot and SBSFU_LoaderI've included the steps I take to integrate my own application below.1. Create Project Name: Applicatio...
Hi,I am trying to modify the SBSFU example provided with STM32CubeU5 to run my own application. I generated the code with STM32CubeMX for IAR by enabling TrustZone and leaving the default values set by STM32CubeMX. I wrote my code, deleted all the fi...
Hi, I’m working on a STM32L552ZEQ.My goal is to generate a pair of RSA keys of 2048 bits using the Trust Zone.Before start using the Trust Zone, I wrote the code to generate the RSA key pair (of 2048 bits) without the Trust Zone, and the average time...
I'm using cmox_ecdh for generating shared key for STM32G431KBT6. I tried using single call API from AES_CBC_EncryptDecrypt example and provided Computed_Secret instead of Key in cmox_cipher_encrypt function but I get bad parameters error. I dWith the...
Is it possible to compute the ECDH shared secret (pubkey * privkey) by using HAL_PKA_ECCMul, replacing the generator X and Y with the public key X and Y and specifying the private key as the scalar value?Thank you.
