Nucelo-h755zi-q flash crc Error

[Ismails]

Hi all, attempting to write data to a specific address in flash bank 1 and calculate the CRC. Using three different CRC methods: flash CRC, software CRC, and hardware CRC, but getting three different values for the same data. The code is attached below. Additionally, the read and write operations are functioning correctly. Could anyone help identify what the issue might be?
