Serial

 * Serial Port Pinout

On the WRV-54G board, the 9 pins look like: - (ttyS1 TX) 1 | 0 o | 2 +3.3V 3 | o o | 4 +3.3V 5 | o o | 6 GND (ttyS1 RX) 7 | o o | 8 GND 9 | o  | - (I've renumbered the pins to the standard pin convention for these connectors)

JTAG
J2 is definitely JTAG. It is using the 20-pin standard ARM JTAG pin layout.
 * Pin 1 on this header is on the edge of the board, closest to the LED.

Pinout: (from Intel) c[] LED5 +3.3V -- 1 o o 2 -- NC      nTRST -- 3 o o 4 -- GND TDI -- 5 o o 6 -- GND TMS -- 7 o o 8 -- GND TCK -- 9 o o 10 - GND GND - 11 o o 12 - GND TDO - 13 o o 14 - GND nRESET - 15 o o 16 - GND NC - 17 o o 18 - GND NC - 19 o o 20 - GND
