Can't build hello world sample project based on tutorial

Hi all,

I recently purchased a DE0_NANO FPGA Board, and was trying to build a ''hello world'' project by following the tutorial step by step. But some weired errors occured during the process. I tried it many times so I am quite sure it was not my problem.

First of all, I named my project "my_first_niosii", so the correct project file name should be "my_first_niosii.sof". But it automatically changed to "my_first_niosii_time_limited.sof". Then it cannot be configured correctly in the NIOS II IDS environment. A window pomped out saying "Opencore and IP Plus(1st line) Time remaining: Unlimited (2nd line)" when I was trying to configure "my_first_niosii.sof" project using "Quartus II programmer" in NIOS II IDS. Finally, I cannot build the ''hello_world'' project because all the errors occured above.

I thought it might be the reason that both of my quartus and nios ii ids are web edition, so they might not support the most complex NIOS II/f microprocessor. I chose the "NIOS II/f" in the SOPC builder in Quartus. Thus, I switched to the simplest "NIOS II" by building another new project. However, it still did not work. Even though it solved the problem of automatically changing my project name from "my _first_nioii.sof'' to "my_first_niosii_time_limited.sof", some erros occured during building the "hello_world" project saying missing some resource files.

I was really confused. I did exactly the same things the tutorial does. I should get the same result as shown in the tutorial! Please give me some suggestions!

Thank you,

Tina
