It's been a while, so I don't remember all the details.
I added a "Remote Update Controller" in SOPC builder. To trigger the reconfig, you then do something like this:
// set address
IOWR(CYCLONEIII_BASE, 0x04, nAddress >> 2);
// disable watchdog timer
IOWR(CYCLONEIII_BASE, 0x03, 0);
// reconfig
IOWR(CYCLONEIII_BASE, 0x20, 1);
In my case, I was only using internal block RAM for my NIOS code. Therefore, I did not have a seperate ELF file to worry about as all my code was included in the SOF file. I used the sof2flash utility to generate a S record file which contained the data to flash to the EPCS.

Hi, kevin
Would you tell where theses code locate? In factory nios program or application nios program? I'm now very confusing with this issue. I want to figure out the reconfiguration process.
Thank you in advance!
