Looking to get the serial console working correctly on this model, but I note that I cannot *send* anything to the serial console when it is connected up.  I can see the Uboot output and various linux kernel messages as the host starts up.

I've soldered on pins for the serial console:

But I can only receive on this connection, so I cannot interrupt boot at the UBoot prompt.  I assume that this means the board has an open circuit somewhere on the TX path, does anything in these photos look obvious?
