Why would making a minor change in RTL cause the serial flash loader to fail?

I have a project that has worked well for some time, but occasionally I will get a build where the .sof file will not allow me to program the attached EPCQ256. I have not changed any project settings...

Hi Gabor,

This error messages means that the device selected is not correct. By right it shouldnt be a problem if everything is the same with just some minor RTL changes.

Another thing is that, have you tried to generate using the other version of quartus? is it having the similar problem?

Thank You.
