Guy:
  Does EFI_CALCULATE_CRC32() cover the flash data that includes PEI module?

Thanks

Update -  it seems that only in the Pei modules a code change doesn't change the crc.
Does it make sense?
if so, is there any interface to calculate the flash data itself in the Dxe phase?

Thanks!

Hi Gao,

I used the EFI_CALCULATE_CRC32 function from edkCompatibilityPkg\Foundation.

Thanks,

Guy

Do you use CalculateCrc32() in BaseLib to calculate CRC32 value for the different buffer?
