First Nios project works with Nios2/e but not with Nios/sf

Hi all

I'm a very beginner with nios II and I have some problems with the first simple test:

I have a cheap "chinesse" CycloneII mini-board with 16 MB sdram and I created a SOPC with:

- Nios 2/e ( Nios2 /s)

- JTAG uart

- PIO (1 output)

- SDRAM controller

- EPCS controller

With Nios 2 SBT , selecting the template "hello world." I've created my first test, and works perfectly with the Nios2/e CPU , but after re-generating the SOPC with the cpu Nios2/s and remake the project, the board doesn't send the famous message to the Nios Console.

Can someone help me ????

Thx very much

    NIOS II/e is free, but /s and /f require a license.

    Assuming you don't have a license, you may be able to use them in time/tethered evaluation mode.
