Hi,  
  
  
  
  
  
\*Are the driver you are using standard release drivers for the Galaxy S?  
  
  
\*Does this crash with other applications, e.g. the demos and tutorials in our SDK?  
  
  
  
  
  
If you are using drivers other than those usually distributed by the OEM/carrier, then you should follow up the issues though our driver bug tracking system rather than on the public forums (email [devtech@imgtec.com](mailto:devtech@imgtec.com) for further instructions if this is the case).  
  
  
Otherwise, if you can send the application or a reproduction of the issue to [devtech@imgtec.com](mailto:devtech@imgtec.com), it will be easier for us to investigate.  
  
  
  
  
  
Thanks,  
  
  
Joe

Thanks for your replay.

I'll send this problem to [devtech@imgtec.com](mailto:devtech@imgtec.com).
  

&nbsp;
  

\*Are the driver you are using standard release drivers for the Galaxy S? 
  

Yes, this is a standard release driver.
  

I don't know why, but the driver have debug symbols.
  

that's why I reached the source of the trouble.
