@Nagarjuna-Reddy It is very difficult to help you if you do not provide technical information about your circuit.

Are you using a USB to TTL converter? What happened to ttyUSB0 and ttyUSB1?

Have you looked at the system log to see if something is wrong?

@Nagarjuna-Reddy I see that you published in another post, and I think you were able to make your custom board start correctly, you should post the solution here, so that other people can get feedback from the experience.
