Before responding to the heart of your question, are you able to debug/run most software? Is it only hostfs that you have issues with?

All of the documentation you need is contained within the rozipfs software template, shipped with the kit. I don't think I can provide anything further than what this documentation already does.

I'm currently running the following tool versions:

Quartus II: 5.0SP1

Nios II: 5.01

The hostfs part of the "zip filesystem" example has worked in every version of the tools since v5.0.

If you decide that this can't work for you, I'd advocate using the following to read/write files onto your target:

Read => cat <filename> | nios2-terminal

Write => nios2-terminal >& terminal.log

Or a combination of the two...

cat <filename> | nios2-terminal >& terminal.log

You could write more elaborate scripts/code using pipes going into and out of nios2-terminal.
