1) I doubt a compressed image will take any longer to configure the FPGA than an uncompressed image. However, the fact it's smaller won't mean you have more UFM to play with. UFM & CFM are separate FLASH areas for 'User' and 'Configuration' use.

2) If your application uses the UFM as a ROM you're likely to want it pre-filled with something. So, you'll want to be able to initialise it. However, if you're using it as a RAM you may not.

Which configuration mode depends on your design. I'm not sure the documentation can do anything other than state what the options are.

Cheers,

Alex
