ls命令在VxWorks目标提示符中不起作用

我是vxworks的新手,在将VxWorks映像从主机加载到目标计算机后遇到了问题。在目标机器上加载图像后(包括构建在符号表中),我在命令cd,ls等中遇到问题.cd命令正在成功但是在cd之后执行ls命令时它显示错误为value = -1 = 0xffffffff(打印错误代码为0x3d0004)。经过大量尝试构建VxWorks映像后,我无法解决问题。请求任何人在这方面取悦。我也不确定cd命令是否成功执行,因为我在执行CD或LS命令时无法在网络上看到任何FTP消息。

可以设置初始目录。在使用import java.text.DecimalFormat; /* amazing. */ public class Cylinder { /* amazing. */ private String label; private double height; /* height of cylinder. */ private double radius; /* radius of cylinder. */ public static final double PI = Math.PI; /*constant Pi. */ private double diameter; private double circumference; private double area; private double volume; private DecimalFormat df = new DecimalFormat("#,##0.0##"); //////////////////////////////////////// public boolean setLabel(String labelIn){ if (label == null) { return false; } else { label = labelIn; label = label.trim(); return true; } } public String getLabel() { return label; } public void setHeight(double heightIn) { height = heightIn; } public double getHeight() { return height; } public void setRadius(double radiusIn) { radius = radiusIn; } public double getRadius() { return radius; } public double diameter() { return radius * 2; } public double circumference() { return 2 * PI * getRadius(); } public double area() { return ((2 * PI * radius * height) + (2 * PI * Math.pow(radius, 2))); } public double volume() { return PI * Math.pow(radius, 2) * height; } ///////////////////////////////////// ///////////////////////////////////// public String toString() { return "\n" + "\"" + getLabel() + "\"" + " is a cylinder with radius = " + df.format(getRadius()) + " units and height = " + df.format(getHeight()) + ",\n" + " which as a diameter = " + df.format(diameter()) + " units, circumference = " + df.format(circumference()) + " units,\n" + " area = " + df.format(area()) + " square units, and volume = " + df.format(volume()) + " cubic units."; } } 或类似命令之前,请尝试更改为计算机的其中一个驱动器(例如cd "/tffs0")。
