I can't get it to work, but the problem is related to the payload size
issue you describe.
I checked out the latest version from cvs to get the updated source
code, but the directory "tools", containing all the java code, was
missing so I had to use the dir from the zipfile. In the cvs version
the apps directory also only contained the Eavesdropper application,
not the FlashViewer, JDebug or TestHarness apps, but I got them from
the zip as well.
The apps/FlashViewer (from the zip) compiled without problems and I
was able to put it on a mica2 mote, but when I tried to compile the
java application tools/com/rincon/flashviewer (also the one from the
zip file) I got this error:
com/rincon/flashviewer/DataOutput.java:35: package
net.tinyos.flashimage.messages does not exist
import net.tinyos.flashimage.messages.JDebugMsg;
^
com/rincon/flashviewer/DataOutput.java:36: package
net.tinyos.flashimage.messages does not exist
import net.tinyos.flashimage.messages.NodeReply;
I can't find "flashimage" anywhere either in the base-tos tree, the
rincon cvs files or the zip file. Without flashimage I couldn't
recompile the java code for tools/com/rincon/flashviewer but
fortunately it was already compiled in the zip file so I was able to
run it.
With apps/FlashViewer on the mote and SerialForwarder running, I ran
the tools/com/rincon/flashviewer java program:
$ java com/rincon/flashviewer/FlashViewer -ping
receive error for com.rincon.flashviewer.messages.ViewerMsg (AM type
161): invalid length message received (too short)
The apps/FlashViewer program demonstrates nicely how the BlockRead and
BlockWrite works, but it would still be nice to have a working app.
Would you mind giving cvs another go so a clean checkout includes
everything you need to get the app to work. (or explain what I'm doing
wrong now).
