Marvell 88W8388 (Xbox360 wlan/wifi/wireless dongle and OLPC XO)

Look for CN1. It is an unpopulated Hirose FH12 0.5mm pitch 10 pin connector, which would normally hold a FFC (flat flex cable) for JTAG. In the OLPC XO, this is on the opposite side of the motherboard, and you can add 34 to the CN1 pad number to get the module pad number. (soldering to the module is easier if you don't have the right connector part)

1. TRSTn
2. IDI
3. TSM_ARM
4. TCK
5. RTCK
6. TDO
7. SRSTn
8. gnd
9. nc?
10. vcc3.3

There is an ongoing reverse engineering effort that may someday result in Open Source wireless firmware for the OLPC XO. (and maybe even for the Xbox360) See the OLPC wiki's 88W8388 article for more info.
