Test F7 SPI CRC Generation

Hello,i have a programm which is sending 2bytes + 16bit CRC from SPI2.There are two STM32F765 on my board. The test programm is generated with CubeIDE and only SPI2 initiallyzed.One MCU is calculating the crc correct and the other is not correct.(Che...

Enabling SBSFU security flags cripples my code

I've ported the SBSFU package for my user app. It works great when only read out protection is enabled. Everything works as it supposed to. However, when I activate other security flags random errors/problems arise in the code. For example, when I ac...

How to Debug Code Executing from OctoSPI / OTFDEC in Keil MDK?

Hi guys,I'm currently utilising SBSFU as an external flash secure bootloader (with all security settings turned off for debug) using the STM32H7B3's OTFDEC (On-the-fly Decryption) peripheral.My user application boots and runs via the OFTDEC and memor...

What is de CRC16 used on SPI peripheral? the Polynomial is configurable, but the init value and reverse or not, is not documented.

I have a SPI on STM32F746 configured:/* SPI6 init function */void MX_SPI6_Init(void){ hspi6.Instance = SPI6; hspi6.Init.Mode = SPI_MODE_MASTER; hspi6.Init.Direction = SPI_DIRECTION_2LINES; hspi6.Init.DataSize = SPI_DATASIZE_16BIT; hspi6.Init.CLKPolar...
