Hi,I am trying to use the STM32Cryptography library to verify the signature of a flash segment, using RSA Encryption and 3072 bit length keys.The signature is generated by a python script and appended to the hex file. The signature has a length of 38...
I could not get wanted result by using STM32F7 calculation unit. The code I borrowed for comparison was from WireShark CRC32 function. It was a table based function for speed. And I compared the STM32 CRC result with bitwise algorithm. I found out th...
I can "Transmit" but the TXE flag never clears and the transmit times out. It's unclear which parts of the bus are fully automated (reset, discovery, etc.) and how much of the CRC is handled, etc. I can see nothing on a scope, but if the chip gets in...
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...
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 ...
