I found both uart_0 and uart_usb in your ptf.

1. since you have jtag connector on your board for download,

use jtag uart as a first test to make sure the kernel start up.

2. use only minimal ptf, with only one uart_0 .

use zImage instead of vmlinux, becaue zImage will print a message driectly to the uart port.
