We jave not hooked up DTR with the reset circuit. So each time we have to 
Reset TINI, we manually press the Reset switch available on the board and 
then issue Reset Command from the JavaKit. This seems to be working for 
Us.

The difference between the Actual file and the file loaded on our board is 
the following line. (which is incidently the first line.) Everything else 
being same. 


:10000000800554494E4940C2AF75C7AA75C75543CC  // On TINI
         ^
:10000000000554494E4940C2AF75C7AA75C755434C  // On Our Board. 
         ^ 

Any ideas why this is happening?
