We're looking to add a serial port to the wl500g to make boot analysis and development easier.
Has anyone done this already? We need to find the proper pins to attach the UART and transceiver chips to on the WL-500g main board.
In my opinion the signal assignment could be following (perhaps - did not check as I don't have the connector plug):
signal ......... COM Port pin ............. 16C552D pin
/CS ............... 14 .................................. 18
/RD ............... 15 .................................. 24
/WR .............. 16 .................................. 20
INT ............... 17 .................................. 34
GND .............. 18 ................................ 12,22
+5V .............. 13 ................................. 33,44
D0-D7 ........... 1-8 ............................... 2-9
A0-A3 ............ 9-12 .......................... 10,14,15,-
