Hello Kris,

I hope the schematics are same for AIR and FIRE. I use OVERO-FIRE. The WiFi uses SDIO on these OVEROS... If you tap the UART, only bluetooth will be affected.. There are no other UARTS assigned to the Wi2Wi module as far as i know...
So you can still use the WiFi after doing the changes to portmux.

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.
