Honored ContributorHalfway thru writing my own ethernet downloader, I decided to check out the alternatives.
The Redboot docs indicate that no port exists for Nios boards. If someone has one, maybe they could post it. u-boot looks more promising. I was able to build for the "PK1C20" board configuration, and it can download and partially run on a 1S10_ES kit board I have. The console works but the ethernet does not, so there must be some critical differences between these boards. The image is smaller than I expected at ~100kB. This is probably smaller than my own downloader code, but with more features. I'd like to see it fully working on the 1S10 board before I spend my days porting u-boot to run on my custom board (The README is rather large). Does anyone know of more ports available or what I need to change to get it fully working on my kit board?
