public class Debugger extends Thread{
public void run(){
Process p = null;
try {
p = Runtime.getRuntime().exec("gdb a.out --interpreter=console");
new Thread(new SyncPipe(p.getErrorStream(), System.err)).start();
new Thread(new SyncPipe(p.getInputStream(), System.out)).start();
PrintWriter stdin = new PrintWriter(p.getOutputStream());
stdin.flush();
stdin.println("target remote localhost:3333");
stdin.flush();
System.out.println("=====================================");
stdin.println("monitor irscan stm32.tap 0x00");
stdin.flush();
} catch (Exception e) {
e.printStackTrace();
}
}
}
class SyncPipe implements Runnable
{
public SyncPipe(InputStream istrm, OutputStream ostrm) {
istrm_ = istrm;
ostrm_ = ostrm;
}
public void run() {
try
{
int length;
byte[] buffer = new byte[1024];
for ( length = 0; (length = istrm_.read(buffer)) != -1; ){
ostrm_.write(buffer, 0, length);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
private final OutputStream ostrm_;
private final InputStream istrm_;
public static void main(String []args ){
Debugger d=new Debugger();
d.run();
}
}
