I have set SERIAL_CONSOLE="115200 ttyAMA2" then why its taking /dev/tty0 ?.
I've lost some of the context on the board you are working with, but
from ttyAMA2, I'm assuming it is an arm board. Have you verified that your
bootloader can pass the kernel bootline properly to the kernel ? It is
(unfortunately) fairly common that it isn't properly passed. If you
modify your configuration to have a built in command line with your
configuration, you may be able to get better setup to debug the
problem.
Cheers,
Bruce
please help.
Best Regards,

What do you have SERIAL_CONSOLE set to in your configuration?
I have set SERIAL_CONSOLE="115200 ttyAMA2". As we are using ttyAMA2 for console.
What is your target device? Do you really have /dev/ttyAMA2 serial port??.
Yes, I have /dev/ttyAMA2 serial port.
Can you try using say poky/master and generate root file system and
try that out ?
another option is to try core-image-core
