Hi Weston,

Thanks for your reply log cat is not running.

Please suggest me some methodology for debugging since I am a newbie in this area.

Any guidance will be a great help for me.

Thanks.

If you run log cat, are you seeing any messages or does it not get that far?

Also, any serial debugging? (sometimes devices have a few pins of the usb connector you can connect and see usb debug messages).

Just because it flashed doesnt really mean anything about being able to boot. I've seen kernel configuration problems cause the inability to boot.

If you do happen to get some sort of serial output, you can enable printk and earlyprintk in the kernel, and see debugging output with dmesg. (I've seen android boot problems that I never resolved WHY it wasnt booting, because even with serial out, the error messages were not obvious).

From above it seems that device is flashed properly but when device is rebooting.
It does not proceed after boot screen.It simply stucks at boot screen.
How do I debug it.
Any suggestions.......
