Hi,

I'm trying to connect two XK-1A boards using the the following XN-file.

Flashing the code

Code: Select all

/*
 * multicore.xc

 *  Created on: Sep 30, 2011

 */

#include <xs1.h>
#include <platform.h>
#include "utils.h"


on stdcore[0] : out port leds0 = PORT_LED_0;
on stdcore[1] : out port leds1 = PORT_LED_1;

void led_loop0(out port leds) {
	timer t;
	unsigned time, state = 0;
	while (1) {
		t :> time;
		leds <: state;
		state = (state + 1) % 0x0F;
		t when timerafter (time + DELAY_0_5_s) :> void;
	}
}
void led_loop1(out port leds) {
	timer t;
	unsigned time, state = 0;
	while (1) {
		t :> time;
		leds <: state;
		state = (state + 1) % 0x0F;
		t when timerafter (time + DELAY_0_5_s) :> void;
	}
}

int main(void) {
	par {
		on stdcore[0] : led_loop0(leds0);
		on stdcore[1] : led_loop1(leds1);
	}
	return 0;
}

fails with the error

Code: Select all

All call records have not exited in Multi-node boot

What am I doing wrong? Has someone a XN-file for multiple XK-1As in stock?

Thanks in advance!
