Hi Bruno,

=

 

I don’t think you can do what you’re trying to do, unless I’m misunderstanding or just not sm= art enough.

 

The EDK from Xilinx ships with drivers= that are not Linux drivers.  Those functions in main below are intende= d for a standalone (no RTOS) system such they can’t just be called from= a user app in Linux.  You are sort of trying to create a user mode drive= r with what you are doing.

 

There is a character mode gpio driver = in the Xilinx git tree, git://git.xilinx.com/linux-2.6-xlnx.git that has been = used previously.  I don’t currently test that driver as we’re i= n the process of getting a flattened gpio driver that is not char driver read= y for mainline.

 

I plan to take a look at the char mode= gpio driver today as there’s another question regarding it on the lis= t.

 

Thanks,

John

Subject: Compile program usi= ng XGpio

 

Hi all,

I'm working with a Virtex2p. I have a running system using:

  • EDK 9.1
  • Crosstool-ng (svn)=
  • linux-2.6-xlnx
  • BusyBox 1.12.1

Now, i'm trying t= o build a small program that turn off leds. I guess it should be something like thi= s:

void main (void){=
    XGpio led;   
    XGpio_Initialize (&led, XPAR_LEDS_4BIT_DEVICE_ID);     XGpio_SetDataDirection(&led,1,0);
    XGpio_DiscreteWrite(&led,1,0xf);    <= br> }


I want to know how to compile it (without EDK). Any suggestion?


Thanks,
Bruno Monteiro
