Ok.. Thanks for the help. I have tried your solution with MicaHWVerify and
i'm still having problems. When i run harware_check java program, i get the
following errors now:
---------- Capture Output ----------
"C:\Program Files\Crossbow\Crimson\IDE.bat"
"C:\tinyos\cygwin\opt\tinyos-1.x\apps\MicaHWVerify" "c:\tinyos\cygwin\bin"
"java hardware_check"

Command: java hardware_check

#############################
Hardware check started
Node transmission failure
Terminated with exit code 0
Also, i have used Serial Forwarder in conjunction with this program and it
shows that the 10 packets that it has tried to write has failed. I used
GenericBase as the fowarder for the base node as suggested by the
MicaHWVerify. Similarly, i used TOSBase as well. I get the same errors
exactly. Does this mean that my Serial Forwarder is not functioning properly
or is there a problem with my JAVA settings?
Thanks and regards.
Amit.

The first problem is simply that you have overwritten the classpath
that contains the tools/java files so it can't find MessageListener.
This is a red herring, so stick with the second java invocation.
The real problem is in your second example where, apparently, serial-
Forwarder isn't connecting to your TOSBase mote. I would backup and use
some of the simpler apps, like MicaHWVerify and CntToLedsAndRfm to
verify that you have all the components working correctly.
Also, I think you can bypass serialForwarder and connect
Sample directly to the serial port that goes to TOSBase if you
set your MOTECOM envvar to [EMAIL PROTECTED]:mica2

Hi.
I am currently trying to run the High Frequency Sampling program in the
tinyos-1.x/apps folder on 2 Mica2 motes. I have followed all the
instructions written in the readme file. However, when i run Sample.class
using the "java -cp . Sample 200 20000" , i get the following error:

When i use "java Sample 200 20000" command, the entire class just hangs and
on the Serial Forwarder, it just indicates the write has failed and nothing
else happens. The HFS mote does not light the yellow LED and no sampling
occurs. Could anyone tell me if there's a solution for this?
Thank you and regards.
