Hello everyone,

I'm going to start programming in tinyos, and I am now interested in knowing
how to debug this kind of devices.
I am working with the "ICradio stick 2.4", and I'm trying to run the
application TestSerial.

I can compile and flash .hex the mote, but when I try to run the java
application gives me an error NullPointerException.

I am working with the cygwin and tinyos-2.0.2-2. I am running the
application with the command $java TestSerial -comm COM3. I confirmed that
the mote is connected to COM3.

$ java TestSerial -comm ser...@com3
Exception in thread "main" java.lang.NullPointerException
at java.util.Hashtable.get(Unknown Source)
at net.tinyos.packet.Platform.get(Platform.java:23)
at net.tinyos.packet.BuildSource.decodeBaudrate(BuildSource.java:201)
at net.tinyos.packet.BuildSource.makeArgsSerial(BuildSource.java:227)
at net.tinyos.packet.BuildSource.makePacketSource(BuildSource.java:138)
at net.tinyos.packet.BuildSource.makePhoenix(BuildSource.java:87)
at TestSerial.main(TestSerial.java:97)


Does anyone know the cause of the problem and/or how to solve it?

Thank you very much,
