Problem about the NIOS II IDE c code

Take a look at the host filing system for Nios II. It only works when debugging and is quite slow, but might suit your needs.

right click on project,

System Library Properties->Software Components->Altera Host Based File System , check "Add this software component"

File will be created in chosen mount point.

Thank you for your suggest.

But, How to assign the mount-point??

Does that mean the file that I creat??

Thank you for your suggest, but could you tell me how to use this method??

or

Do you have any document,

could you give me some advice??

Choose a writable mount point (user folder), folder must exist, and run your Application

FILE *fpl;
fpl=fopen("qq.txt","w");
fprintf(fpl,"111 %d\n",velocity);
fclose(fpl);

File qq.txt should reside there.

I have to try this code, but it seill doesn't work.

May I ask some question, Should I have to set up anything in NIOS II or file??

MY verisonal is NIOS II 9.0v, and I try that code directly.

I write in my c file of NIOS II, But it doesn't work.

and I try to Build the *.txt file first.

It sill doesn't work . Could you help me other advice. Thanks

Did you activate the host file system?

right click on project,

System Library Properties->Software Components->Altera Host Based File System , check "Add this software component"

After running your program file will be created in chosen mount point.

I just find the file of Host file system.

Because my NIOS II IDE is 9.0v

So, I never used that you said.

And, may I ask you??

Do you have any example?

I try to find the example,but I didn't find that.

and I try to use the Host file system.

that open another project file.

Dose that mean I have to write my c-code to the Host file system file???

Or, I can build blank project and include the Host file system project or write the Host file into the function?

And then, call the function in main function?

Thank you for your help, Thank you.
