Hi David
then press S+Power the u-boot will enable the ttyS0. and wait 3 seconds(in old u-boot, it's 5 secs)
form the serial input.
if nothing input: u-boot will boot the kernel.
if something input: u-boot will goto u-boot's console.
problem is the RXD pin will generate some garbage character when the serial console is not connect to PC.
so when not connect the ttyS1 with PC. the u-boot will stop at u-boot's console.
