How to use SHA1 function in STM32CubeIDE?

I am trying to implement the sha1 function using the cryptographic library offered from STMicroelectronics. I believe I have properly imported the library as per the directions in Security:Getting started with the Cryptographic Library - stm32mcu. Fr...

STM32U5 Debug in RDP 0.5 With STM32CubeProgrammer

Hello,I am trying to start a debug session with STM32CubeIDE v1.11.2 on my board locked on RDP 0.5.I loaded a valid secure firmware which jumps into the non-secure firmware before setting RDP 0.5.I could connect STM32CubeProgrammmer and flash the non...

Resolved! How do I add the CMOX crypto stack to an existing project?

I have an existing STM32L433 project (CubeIDE 1.8.0) to which I want to add AES functionality via the CMOX crypto stack (https://www.st.com/en/embedded-software/x-cube-cryptolib.html). I am unclear as to where I am supposed to put the .a file, and al...

Resolved! STM32H735RGV6 and STM32H725RGV6 software compatibility?

We have a design based on STM32H735RGV6. We are trying to move our design to STM32H725RGV6.These two MCUs are pin compatible and can be used in the same design without changing the board design.However, we are not sure about using the same software i...

We are facing an issue related to the STM32H753 MCU , CubeIDE version 1.10.1 .We compiled our project successfully with all needed scripts for generate the SBSFU file + sfb bin file.The bin file programmed into the internal FLASH via the Cube Program...

R4 register corruption in STM32L562(ARM Cortex M33) when switching from secure to non secure mode in STMCubeIDE

On switching from secure to non-secure mode using a function pointer (with the cmse_nonsecure_call attribute) in STM32L562(ARM Cortex M33), general purpose registers R0-R4, R12 and floating point registers S0-S15 are not restored when back in secure ...

Resolved! How to enable debugging of SECoreBin application

Hi,I tried to execute my custom SBSFU_UserApp.bin on the STM32H7B3I-DK board and I get error for Header signature verification failure in slot SLOT_ACTIVE_1. I have made changes in se_crypto_bootloader.c file for adding RSA signing verification in pl...

STM32CubeIDE support for TFM Application ?

I wish to try the TFM application on my B-U585I-IOT02A demo board. But the support for STM32CubeIDE has disappeared in FW_v1.1.0. Is there any reason for that, or can I copy the project from patch_cube5_v.1.0..2, though the source files have signific...
