    Hi Ito-san,

      Once you generate your program binary, you can use CRC32 with the polynomial equal to 0x04c11db7 to generate the golden checksum for the program image. After you load the program image to the flash, you can recalculate the checksum to see if it is equal to your golden checksum value. You can use Uniflash to calculate the CRC value for the image that is stored in the flash.
