This feature is one of the biggest draws for us to NiosII/Eclipse. If it can work, I hope you figure it out soon. Better yet, I hope this critical feature is made an order of magnitude simpler.

I still don&#39;t quite understand the need for so much setup. It&#39;s not like the EPCS has variable pin-outs.

Probably missing something here, but couldn&#39;t interface simply allow us to select the .SOF, .srec, and an address for the bootloader to use?

Since the bootloader is no longer needed once booted, it could reside almost anywhere. Or a simple to use alternative would be a Bootloader IP in SOPC that you add to your design and set your reset vector to. It&#39;s my understanding that the bootloader code only requres a single M4k block.
