Question

我正在使用BeagleBone Black并尝试让bonescript运行。我正在使用最新更新和节点v0.10.21和bonescript 0.2.4的最新版本运行Debian Wheezy。我能够闪烁内部LED，所以我很确定我的安装工作正常。我的问题是我无法控制任何P8或P9 gpios。使用bonescript网站上的示例我正在运行以下脚本。我不确定这个错误究竟意味着什么，所以即使有人能指出我正确的方向，我也会很感激。

谢谢 Scottt

=============================================

var b = require('bonescript');
var led = "P8_3";
var state = 0;

b.pinMode(led, b.output);
toggleLED = function() {
    state = state ? 0 : 1;
    b.digitalWrite(led, state);
};

timer = setInterval(toggleLED, 100);

stopTimer = function() {
    clearInterval(timer);
};

setTimeout(stopTimer, 30000);

=============================================== ====== 我打开了bonescript调试并得到以下关于无法找到devicetree片段的输出。

我们已经分叉了bonescript并发布了新包。我们遇到了同样的错误，现在通过在原始的bonescript中重写大量代码来解决所有问题。您可以在项目中安装和使用。 https://www.npmjs.org/package/octalbonescript
