Hi,There is No-Stretch Get Memory Checksum command in I2C bootloader, Does someone know the CRC algorithm used?The UART & SPI bootloader, Host can set the CRC polynomial & CRC initial value in Get Checksum command, but there is no such description 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...
Hi,I'm playing with Nucleo-u575zi and GPIO_IOToggle_TrustZone example.Everything is working as expected.I want to be sure that systick of secure zone is never blocked by nonsecure zone (e.g. setting PRIMASK_NS =1). In secure mode, at startup, I then ...
Device: STM32L4S5Trying to run x-cube-aws v2.2.1I've successfully flashed the B-L4S5I-IOT01_STSAFE_Provisioning binary (output below)Start provisioning of STSAFE-A Force STSAFE-A provisioning Launching STSAFE-A pairing Check if Pairing Host keys...
Hello STM32U5 community,I was making a few attemps with my B-U585I-IOT02A demo board and TF-M. I am afraid I have irreversibly locked the MCU.Here is what I did:run regression.shset RDP level 1 with the Programmer despite the warnings, because I forg...
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 ...
Hi ST Team,I'm working on a project where I'm using SBSFU as bootloader (on a STM32H7). When I download the new firmware image, SBSFU reboot the system and start execution (decrypting image, validating and so on...). While SBSFU is doing these action...
Hi,I am working on enabling hardware cryptography in nucleo-u585ai board.Can you suggest an example for enabling hardware cryptography? or Is it enabled always?How to test or know that data is encrypted?Thanks,Akanksha
Hello,A hard fault exception is being thrown when I flash the SBSFU_userapp.bin file with the STM32Cube Programmer to device that uses the WB55 MCU architecture (M4/M0+) and then try to run the SBSFU example in Tera Term. The secure engine is first i...
