That's strange... I don't know where sof2flash gets the information about the size of the EPCS device.

If you open the srec file in an editor you should also be able to find how big is the image to see if it fits in your flash. But from what I see you don't use compression, so it is most probably bigger than what the EPCS can get. Add the --compress flag to the sof2flash command to activate compression.

You shouldn't need to do a different footprint, the EPCS16 can be found in an 8-pin package, just like the EPCS4.
