Hi Community,I'm porting STM32G071 SBSFU to STM32G0B1RE and Customizing UART to USB CDC.I'm using Nucleo-G0B1RE dev kit and STMCubeIde for development.1. I'm able to build, load, run both STM32G071 SBSFU and UserApp without any changes. but when I ch...
Hi,I changed symbol in the properties tab to adapt STM32G0B1xx drivers causing hard fault after loading User App. The hard fault occurs in sbsfu while verifying the user fw signature.can someone help me why fw signature verification failed just chan...
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...
