In the eLearning course 'STM32L4 Training' (community.st.com - Academy) there is an error in the content : when you open the section 'STM32L4 training: 02.4 - Hands-on CRC unit', it actually plays contents about I2C, not about CRC. Please correct thi...
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...
I've been implementing I2C communication between F401CCU6 and Nucleo F746ZG, while adding CRC I got different outputs, Nucleo provides configurable CRC peripheral, while F401 is by default set to 0x4C11DB7 (https://www.st.com/resource/en/reference_ma...
Hi,the HW PEC generation of the I2C Interface has two limitations that i have not been able to work around until now. The PEC calculation is reset after a stop, but can not be initialized after start. If you want to program a SMBus Slave that is capa...
Background:I am working on a project that uses the STM32H7B0 processor on a custom board. The firmware is loaded by ST SBSFU bootloader STM32CubeExpansion_SBSFU_V2.4.0. I have used 2_Images_ExtFlash example as a template, and our firmware is stored a...
I have been able to build the STM32H7B3I_DISCO_2_Images_Loader from STM32CubeExpansion_SBSFU_V2.3.0 project targeting STM32H7B3I_DISCO board. I have also been able to build the example file and use the Ymodem protocol for sending the UserApp.sfb file...
