Probably not. On the older versions (non-Storm), the Wifi/bt chip is connected to a mmc port.
This is still most likely true. (I have not examined a xxxStorm version Overo.)
The uart does not have the performance to run at WiFi speeds. (The mmc port is 4-bits wide.)

[Gumstix-users] overo air, does the wifi needs the uart ?

I need 3 uart on my design and on the gumstix website, it is written that the uart 2 is used on the wifi/bt module.  I know that the bt uses the serial protocol but does the wifi need it too ?

I will not need BT but could need wifi.

I know by modifying the portmux we can select the route of the signal, but I'm not sure if the wifi will need the uart.

Thank you for your help.
