Can you post the "logcat -s *:W" output?

Regards,

Arun

 Where should i type this ( logcat -s *:W) command ..I can't type anything on terminal because i didn't get any shell prompt ..I get the following line repeatedly  

          [   19.731201] request_suspend_state: wakeup (0->0) at 19698468701 (2000-01-01 00:01:01.926217452 UTC)

Hi Adheeth,

Can you make the loglevel to 7?

Also try the command logcat alone.

Regards,

Arun

Hi Arun

    I compiled it again and i am posting the new boot log..It is almost similar to the boot log  i found in

   TI Android JB-4.2.2-DevKit-4.1.1 Developer Guide..

But i didn't get a prompt shell and android logo..So i cant type anything on the terminal (logcat) ..

  Here is the boot log

Hi Arun

           This is my serial port settings. I didn't  make any changes in flow control settings of mini-com.

    | G - Software Flow Control : No                                        |
    |                                                                       |
    |    Change which setting?                                              |

Thanks and regards

Hi Arun

           I changed Hardware flow control to 'NO' . Also  pressed 'ENTER' key when it stuck, then i got the prompt shell. Thanks a lot for your help and valuable inputs

Me too face the same problem some time for JB. If i connect the device with any other PC it works well. 

You too try once may be you will get result.
