How can see the error message on kernel?

Dear Sir.

Kernel version : 4.4.13

I'm try to develop the network device on my board.

Anyway, I want to check error message, but my kernel is not show to me.

igb_main.c is use the netdev_err() or netdev_info() API to print error message.

But i'm can't see the any message on my shell.

How can enable the debug message on my kernel?

thank you
