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...

So, for example:uint8_t test_crc[] = "1234"; uint32_t crc_val = HAL_CRC_Calculate(&hcrc, (uint32_t*)test_crc, 1);Should be working? Are these 4 bytes making one 32 bit word? What would be the proper implementation of calculating CRC of any uint8_t ar...

... and when fed different data it gives different result so i guess its working (somehow)

I've been testing it that way:uint8_t test_crc[] = "12345"; uint32_t crc_val = HAL_CRC_Calculate(&hcrc, (uint32_t*)test_crc, sizeof(test_crc)-1);Nucleo spits out 0xBD9AB747 as it should be according to crccalc, the point is, if F4 polynomial is 0x4C1...

Wrong CRC-32 — HAL_CRC_Calculate output on STM32F401CCU6 Blackpill

STM32F401CCU6 Blackpill failed connection. I am currently programming blackpill via STM32F7 Nucleo board in STM32Cube, it worked for a while on two Blackpill boards, but now it is not allowing to Erase flash memory, tried almost everything
