 UART on J13 of Development Board

Hello, just starting to play with my new Carambola2 Dev Package.

I see the boot process and get the console on the USB mini connector using PuTTY but I see nothing on the connection on the 1x20 headers.

I have pins 1 & 2 of J13 connected through a pair of BSS138 FET's as level shifters to a serial port on a Arduino which runs at 5V. This setup has been working for me on OpenWrt running on a Buffalo WZR-600DHP which uses an Atheros 7161. Of course the Buffalo doesn't have the FTDI USB adapter.

I don't know how to interpret the 11 UART_TX >>- notations on the schematic, are all these connected on the board as shipped?

Do I need to place or remove some jumpers to connect J13 or disable the FTDI adapter?

Thanks!

Please mark this one as dumbass... I was connecting to J12 not J13, all works as expected when I connect to the right pins.

Sorry for the noise.
