Question

我正在使用wiringPiISR获得核心转储＃

Java运行时环境检测到致命错误：＃内部错误（os_linux_zero.cpp：254），pid = 6552，tid = 1866855520 致命错误：抓住未处理的信号11

＃ JRE版本：OpenJDK运行时环境（8.0_66-b01）（内部版本1.8.0_66-internal-b01）

Java VM：OpenJDK Zero VM（25.66-b01解释模式linux-arm）无法编写核心转储。核心转储已被禁用。

要启用核心转储，请在再次启动Java之前尝试“ulimit -c unlimited” ＃如果您想提交错误报告，请访问：

http://bugreport.java.com/bugreport/crash.jsp ＃

我该如何解决这个问题？

我的代码是：

import com.na7kr.GPIOController.GPIOController;
import com.na7kr.Utils.Utils;
import com.na7kr.rpi_gpio_controller.Rpi_gpio_controllerApplicationUI;

import com.pi4j.wiringpi.Gpio;
import com.pi4j.wiringpi.GpioInterruptCallback;

public class Interrupt {
Rpi_gpio_controllerApplicationUI mApplication = new      Rpi_gpio_controllerApplicationUI(); // NO_UCD
                                                                                        // (use
                                                                                        // private)

// ***************************************
public synchronized void GetInput1(int trigerpin, int outputpin) throws InterruptedException {
    System.out.println("<--Pi4J--> GPIO interrupt test program");

    // setup wiringPi
    if (Gpio.wiringPiSetup() == -1) {
        System.out.println(" ==>> GPIO SETUP FAILED");
        return;
    }

    Gpio.pinMode(1, Gpio.INPUT);
    Gpio.pinMode(2, Gpio.INPUT);

    Gpio.pullUpDnControl(1, Gpio.PUD_UP);
    Gpio.pullUpDnControl(2, Gpio.PUD_UP);

    Gpio.wiringPiISR(1, Gpio.INT_EDGE_FALLING, new GpioInterruptCallback() {
        @Override
        public void callback(int pin) {
            System.out.println(" ==>> GPIO PIN " + pin + " - INTERRUPT DETECTED");
            Utils.Output_WriteDebug(true, "1");
            GPIOController.INSTANCE.mGPIOPins[outputpin].toggle();
            mApplication.refreshGPIOPinState();
            Utils.Output_WriteDebug(true, "2");
        }
    });
    Gpio.wiringPiISR(2, Gpio.INT_EDGE_FALLING, new GpioInterruptCallback() {
        @Override
        public void callback(int pin) {
            System.out.println(" ==>> GPIO PIN " + pin + " - INTERRUPT DETECTED");
            Utils.Output_WriteDebug(true, "3");
            GPIOController.INSTANCE.mGPIOPins[outputpin].toggle();
            mApplication.refreshGPIOPinState();
            Utils.Output_WriteDebug(true, "4");
        }
    });
}
}

我的代码中存在此问题，还是需要发送给Java？

Answer 1

我改为PI-J的1.1-SNAPSHOT，问题就消失了。
