This kernel is not mine.
It was built like any other via Jeremy's Git Repos.
Will check serial console enabled via .config.

Thanks

That should definitely work for baremetal kernel. Does your kernel have
serial support built-in?

Are you sure your serial port settings on the other computer are ok?
Try using "minicom" and playing with the different flow control
