I am using the SBSFU STM32CubeExpansion_SBSFU_V2.6.2 version for my custom board STM32H743VI controller. I have ported the STM32H7B3I-DK project for H743 controller for COM port and changed the crypto scheme to SECBOOT_ECCDSA_WITHOUT_ENCRYPT_SHA256. ...
Dear Sir.I am trying to work with the examples of TFM_Appication and SBSFU_Boot examples of STMCube_FW_U5_V1.2.0 when compilng I get the error Error: Missing option '-S' / '--slot-size'.postbuild.sh failedmake[1]: *** [makefile:92: post-build] Err...
Hi Guys,Ported SBSFU 2.6.2 to STM32G0B1CEU6 (512K FLASH and 64K RAM) based on Nucleo-G071RB example.Modified mapping_fwimg.ld as below: /* Slots must be aligned on 2048 bytes (0x800) */ /* swap (4 kbytes) */ __ICFEDIT_SWAP_start__ = 0x0804...

Hello all,I have a question about possibility of splitting/dividing FLASH sector for active/download image slots.A bit more context... My target MCU is STM32F756ZGTx, here is its FLASH memory map:What we want to do is: assign sector 4 (128 kB) and se...
Good morning, I am facing an issue related to the usage of the CRC on the G070RB microcontroller (and user manual RM0454), specifically concerning the use of hardware-based CRC-16 MODBUS for a project currently under development at the company where ...
Hi ST fanboys, I am using the STM32WL55 device and have implemented the latest cryptolib (4.1).This is all working fine with correct AES encryption and decryption, up to the moment that I start implementing the low power features and switch of all un...
I am unable to import the TFM app for the B-U585I-IOTO2A board using MacOS Ventura 13.5.1. Every time I attempt it the importer takes a long time, then fails with a 'Fail on internal error' message. I am using the Import STM32Cube Example method of i...
Hi,I've been exploring cryptography support on the STM32 uCs, especially on the L4 series. I'm able to run the X-CUBE-CRYPTOLIB code to perform AES-GCM, but it's very slow. It takes roughly 4ms to encrypt and tag 80 bytes, with a master clock of 8MHz...
