ok, I was able to flash my epcs using a .jic file and usb blaster.

then I was able to send a file from the PC through uart to nios and have nios buffer it in sdram and then write the file to flash at address 0. this is working! :D the file type I used was a .rbf and did byte reversal on all bytes of the file. I can power cycle and boot from the newly updated image written to address 0 of the epcs!!!

The next step is to move the file to another location in flash so that I can have 2 images and use the remote update circuit to do a reconfig to the app image from the factory image.

The question is, what effect does setting "Device and Pin options" > "Configuration mode" > "REMOTE"

have on the output .rbf file?

why do I need to tell quartus that the build is for remote configuration? Should both the factory default and the application configuration files use this option?

I am not sure why it is necessary if I have the remote update HW in my SOPC?
