i posted this in the software forum, but perhaps it's really a hardware issue: According to cyc_c51014.pdf, only the upper areas of EPCS can be protected, not the lower areas.
So I can protect my application but not the firmware&bootloader (or protect everything).
Is this correct?

This is the weired thing when i saw this part of the document. Why Altera try to protect the application part, not the default part? Or just our understanding problem?
