Manual checksum verification of CFM0

Hi Dennis,

a .pof file is a container holding multiple configuration bitstreams, e.g. ufm, cfm0 and cfm1, additional describing text. Checksum is calculated over complete file, therefore it's always different from checksum of individual configuration streams and can't be related to it. User code is contained in .pof header but I don't know how the default value is generated. I believe it can be optionally set to a dedicated number in project options. But it's not copied to binary configuration bitstreams as far as I know.

Regards Frank
