Thanks Harald!
For programming I use jLink-JTAG
On my board well work program compiled under CrossWorksARM(last version):
#include "lib/AT91SAM7X256.h"
#include "lib/lib_AT91SAM7X256.h"
void delay_ms(int c) {
  int i;
  for (i=0;i< c;i++);
}
int main() {

  AT91F_PIOA_CfgPMC();
  AT91F_PIO_CfgOutput(AT91C_BASE_PIOA, AT91C_PIO_PA0);
  AT91F_PIO_Enable(AT91C_BASE_PIOA, AT91C_PIO_PA0);
  AT91F_PIO_CfgPullup(AT91C_BASE_PIOA, AT91C_PIO_PA0);
  AT91F_PIO_SetOutput(AT91C_BASE_PIOA, AT91C_PIO_PA0);
  AT91F_PIO_ClearOutput(AT91C_BASE_PIOA, AT91C_PIO_PA0);
  for (;;) {
    AT91F_PIO_SetOutput(AT91C_BASE_PIOA, AT91C_PIO_PA0);
    delay_ms(1000000);
    AT91F_PIO_ClearOutput(AT91C_BASE_PIOA, AT91C_PIO_PA0);
    delay_ms(1000000);
  }
}

....

PLL filter and quartz same that in Atmel-EK.
May be for get running ethernut on at91sam7x256 I must do something else?
