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
