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.
