Hello!

I have the similar task.

Please advise how to replace the content of EPCS4 by means of NIOSII?

The AS configuration schematic on a custom board is as follows:

The original .jic file was programmed into EPCS4 in-factory via JTAG ( SFL ).

To make in-field upgrade I plan to make NIOSII replace the original .jic file inside EPCS4 by a new one.

After that replacement the next power-down/power-up cycle will load an upgraded version of .jic from EPCS4 into Cyclone IV.

I know, that this approach has some drawbacks and risks, but I think it is the simplest to implement.

Is there an Altera document, that describes how to make what I need?

If not, then please advise how to make it.
