请教一个DE2 DEMO的问题

yf.x

在友晶的官网下载DE2_System_v1.6，在做DE2_SD_Card_Audio实验时不成功
工具：Quartus II 9.1 web edition + NIOS II 9.1

按照readme，先在Quartus II里下载
然后打开nios ii 指定workplace为 DE2_SD_Card_Audio，
提示“project conversition failed for project hello_led0 with the following error:
error loading manged make project information for project hello_led0.
the tool definitions used to create the project are available."

DE2_SD_Card_Audio
-----------------

This designs uses a Nios II system to demonstrate how to read from the SD card. The software reads WAV files from the SD card and plays it through the LINE OUT line. Simply put a SD card into the slot on the board and connect some speakers to the LINE OUT port.

Preparing the SD card
---------------------

To prepare the SD card for reading by the design, it should be formatted using a FAT16 file system. Then WAV files can be copied on to the card. Note that if you want to add a file after you've removed the card from the computer, you must reformat the card first and then re-add the files.

Running the Design
------------------

1) Launch the Quartus II software.
2) Open the DE2_SD_Card_Audio.qpf project located in the <install path>\DE2_SD_Card_Audio folder. (File menu -> Open Project)
3) Open the Programmer window. (Tools menu -> Programmer)
4) The DE2_SD_Card_Audio.sof programming file should be listed.
   Check the 'Program/Configure' box and set up the JTAG programming hardware connection via the 'Hardware Setup' button.
5) Press 'Start' to start programming. The design should now be programmed.
6) Launch the Nios II IDE.
7) Switch the workspace to the <install path>\DE2_SD_Card_Audio folder.
8) Build the project. (Project menu -> Build All)
9) Run the project on the board. (Run menu)

1楼的错误是在完成第7步后出现的，不知道是哪里操作有问题。

ok,又没人了我，自己猜测：光盘里的例子都是在6.0版本下作的，到了9.1版本，NiosII IDE发生了很大改变

以前是一个application加一个library，现在是一个application加上DSP，所以在NiosII里的工程应该要重新创建才能使用。还是先看看文档，学习了再发言
