【转】使用脚本与RedBoot协作

搞嵌入式系统,用惯了Windows下的超级终端调试ARM程序,每次都要键入一大堆的字符,重复,重复,再重复。
为了减少无用的工作,开始寻找一种能自动与RedBoot交互的方法。
其实,可以有两种思路,一是自己实现类似超级终端的程序,支持XModem协议,这样交互过程就可以通过程序来控制。二是使用类似Expect的思路,使用其他的程序控制已有的通信程序。第一种方法工作量较大,而且很多时候是在reinvent the wheel,不可取;第二种方法应该是研究的重点。

SecureCRT正好提供了类似Expect的功能,它支持脚本来操作与通信的另一方的交互的能力,从而实现交互的自动化。SecureCRT支持三种脚本:vbscript, javascript和perl。前两种只要安装了IE4以上的浏览器的操作系统就支持,最后一种perl需要安装perl解释器,windows下最好的选择就是ActivePerl了。

下面是一段perl脚本来完成自动下载可执行文件demo.bin到目标板上并运行的例子:
    # $language = "PerlScript"

    # $interface = "1.0"



    use Win32::OLE;

    Win32::OLE->Option(Warn => 3);



    $true = 1;

    $false = 0;



    $crt->Screen->{‘Synchronous’} = $true;

    $crt->Screen->Send("n");

    $crt->Screen->WaitForString("RedBoot> ");

    $crt->Screen->{‘Synchronous’} = $false;



    $crt->Screen->Send("load -m xmodem -c 0 -b 0x00600000 -rn");

    $crt->FileTransfer->SendXmodem("demo.bin");

    $crt->Screen->WaitForString("RedBoot> ");



    $crt->Screen->Send("gon");

    $crt->Screen->WaitForString("(y/n)");



    $crt->Screen->Send("nn");

在这个脚本基础上可以很容易的增加GUI功能,让文件可以由用户自己选择。

使用Expect进行下装的脚本如下:(以下代码来自于eCos mail archive)
