The gnICE features four auxiliary signals routed to solder pads, located besides the Mini-USB Jack.
RX and TX are 3.3Volt TTL Signals they may not be connected to RS232 typical +/- 10V UART
signals
Utilizing the Serial Interface
The gnICE auxiliary Serial Interface can be used with the standard Linux ftdi_sio driver. In case your
kernel version already includes following patch, ignore this section. Otherwise it’s recommended
that your patch your HOST PC kernel with this patch.
gnICE gnICE+
It is also possible to utilize the Serial interface without this patch applied.

Description
UART RXD (3.3V IO) signal should connect to Blackfin TXD
UART TXD (3.3V IO) signal should connect to Blackfin RXD
This is a General Purpose IO Signal, which can be used to
RESET the board
In case the gnICE is connect to the board via the JATG header
this can be left unconnected
