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...

Hmm well I am still missing something here then.

I have been using 'elf2hex' to convert the software elf to an appropriate hex file, with the base and end addresses pointing to the on-chip ROM used to hold the software but to no avail.

The CPU reset vector points to the on-chip ROM and the cpu relies on sdram for normal operation.

Thanks again!
