PIO set and clear bits

Ok, now the "Enable individual bit setting/clearing" option in the sopc builder is checked for my pio (it must be the right pio because i only have one).

I regenerated the BSP in the "Nios II 9.1 Software Build Tools for Eclipse". Afterwards i did a full rebuild.

Result: The macros IOWR_ALTERA_AVALON_PIO_SET_BITS() and

IOWR_ALTERA_AVALON_PIO_CLEAR_BITS() still do not work. From the debug messages i can see that they must have been called ("Msg = set_bits", "Msg = clear_bits").

Is there any possibility to check if the pio now really has the set/clear registers?

My source code:

# include "sys/alt_stdio.h"# include "sys/alt_sys_wrappers.h"# include "system.h"# include "altera_avalon_pio_regs.h"# include "Msg.h"# include "Str.h"# include "io.h"

static char c;

static int n;

int main()

{

alt_putstr("\n\nNios ii speaking...\n");

/* Event loop never exits. */

while (1)

{

n = read(0,&c,1); // read one char from stdin/0

if( n == 1 )

{

Msg_DataIn(c);

}

if( Msg_Available() )

{

alt_printf("The message is: %s\n",Msg());

if( Str_Equal(Msg(),"set_bits") )

{

alt_putstr("Msg = set_bits\n");

IOWR_ALTERA_AVALON_PIO_SET_BITS(PIO_0_BASE, 0x0003FFFF);

}

if( Str_Equal(Msg(),"clear_bits") )

{

alt_putstr("Msg = clear_bits\n");

IOWR_ALTERA_AVALON_PIO_CLEAR_BITS(PIO_0_BASE, 0x0003FFFF);

}

if( Str_Equal(Msg(),"on") )

{

alt_putstr("Msg = on\n");

IOWR_ALTERA_AVALON_PIO_DATA(PIO_0_BASE, 0x0003FFFF);

}

if( Str_Equal(Msg(),"off") )

{

alt_putstr("Msg = off\n");

IOWR_ALTERA_AVALON_PIO_DATA(PIO_0_BASE, 0x00000000);

}

Msg_Clear();

// alt_putchar(c);

// write(1,&c,1); // write one char to stdout/1

}

}

return 0;

}
