Stratix II Remote update without NIOS

All remote update examples and designs seem to use the NIOS as a wrapper for all this. I don't want to insert a NIOS into the design for this sole purpose. My idea was to always have a factory ...

Yes it is the megafunction. There is also a ready made sof file that contains only the SFL, that you can directly program into the FPGA.

The layout seems fine, but are you sure that the MSEL pin should be connected to 3.3V? I don't know about the Stratix II (never used it) but I know that on the Cyclone III you must use a 2.5V (the PLL analog supply).

Checking the CRC should be enough. You'll probably need to write a state machine that can instruct the EPCS to jump to the correct address, and then read the data to check the CRC.
