Boot NIOS from on-chip memory ONLY

I'm trying to use a NIOS on a custom board. As there is no JTAG interface, I need an alternative method for downloading my software to the NIOS once it is initialized. Many of the examples out...

Ok sorry, that didn't really make that much sense. I think I was confused on what you meant.

The planned architecture is to have the compiled software located in an on-chip ROM. The software will then need to be copied over from ROM and into RAM. This should allow me to reload the software in the event of a cpu reset.

Based on this, I am thinking I will need to write a seperate boot loader which copies the code and then jumps to that location in RAM. Does this make sense? Or am I missing something?

Thanks!
