fopen don't create

[Altera_Forum]

Hi ! 

 I was trying to use (fopen) & (fclose) to dump data to PC in Nios IDE. The file was never created.  I didn't understand. I have the Nios II 8.0, and in this version doesn't have the host_filesystem example (I saw this in other thread). I downloaded this, but it doesn't appear in the templates options menu, when I will create a new project.  Somobody can help me ?

Obs.: I use the Cyclone III, and the host_filesystem runs in cyclone II,cyclone I and stratix...

The host filing system only works when you're debugging. It uses a feature of GDB to implement the host-side filesystem.

Thanks friend. 

 But I resolved my problem.  Go to project folder in Nios II-->>System Library Properties ->> System library >> Software Components>> set the box "add this software component"  And finished, now I can use fopen() and fclose(), in Debug mode.

how did you manage to use the calls fopen and fclose and fwrite ??

ittiam, 

 The only way to get this to work directly to your PC is to use the host filing system. It's not fast, so don't expect excellent performance...adequate for debug only...In fact, it can only be used in Debug mode!  Cheers,  -slacker
