TINI does not boot

Hi to everybody. 

I am working with TINIM400/TINIS400 originally supplied by Dalsemi, 
TINI1.12, Java j2sdk1.4.2.

For debugging I use

tini_debug_400.tbin instead of tini_400.tbin
(TINI1.12 distribution)

Loading my applications (compiled into slush) worked fine for a long time, 
after loading booting was not a problem, the application also worked.

After some modification of the application I again loaded it using the 
standard procedure. But after that TINI refused to boot. 
TINI did not boot at power up neither after Reset and "E" 

I tried several times, also verified the files and tried to set up the 
original state of TINI again (tini_400.tbin and slush_400.tbin), no success.

After cross checking the module in another TINIS400 socket board 
(same effect) I tried to load my application into another TINIM400 module. 
Unfortunately the second TINI400 module is now also inactive 
(does not boot). Therefore I cannot believe in a hardware defect. 

Could it be possible that my application set some bits which prevent 
TINI from boot? 

How can I recover the original state? 

Here is the procedure I used (original JavaKit protocol)

After typing "E" nothing happens. Switching off and on power supply also 
does not work (regulated power supply, 5.0 V). 

I am pretty desperate. 

Thank you for any help. 

Regards

Klaus
