Hi all,I'm working in a project (with STM32L462) in which we're building our own bootloader to perform secure boot and firmware upgrade. There are some issues we're still struggling with, regarding protection of our code (and data). Hopefully someon...
I set up a very simple test project. It is a .ioc file from another project to which I wanted to add a virtual com port interface. I added the vcp in the cube plugin and generated the code. However, if I include a CDC_Receive_FS() function this gets ...

Hello all, When I had a beautiful STM32U5 in hand the world was still good.But now I have a comprehension question about the STM32L0, I have an 8-bit buffer and now the fastest way to AES decrypt/encrypt this data is via DMA with active burst mode. T...
Hi,We are migrating our code from using the legacy crypto lib to the libSTM32Cryptographic_CM4.a.I can not find api document describing the functions etc, is there any thing like there was for the legacy lib (like https://www.st.com/resource/en/user_...
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 ...
