Stm32CubeIDE generate bin file with padding 0 but load it with padding 0xFF

[dming.4]

Today when I generated CRC from output binary file I found it did not equal the data in the board. Then I check the data in board , I found the data which loaded by stm32CudeIDE was padding with 0xFF, but the stm32CudbeIDE generate the binary file with padding 0.
