As far as I can see if I select 'Active serial configuration' it generates a POF (which can be compresed if I select this option) and a SOF (which doesn't get compressed irrespective of the check-box).

If I select 'passive serial configuration' the compilation fails with an error "serial flash loader must be used with active serial configuration".

POF file size (uncompressed) is 524,473 bytes

POF file size (compressed) is 131,257 bytes

SOF file size is 140,509 bytes in both cases.

Is there a way to compress the SOF file, or a way to get the programming file converter dialog to accept a POF instead of a SOF?
