After the OS boot, the connection between the two processors is established and
working. For this reason, it is impossible to connect an external Host PC through
microUSB connector CN6 (without J18 jumper inserted), since it would result in the
unusability of the shared serial port.The same situation occurs when trying to
communicating with UDOO board through pins 0 and 1 of the Arduino Due – pinout
compatible pin headers, since SAM3X8E UART Serial Rx and Tx line are wired also on
these pins.
In case it is necessary to talk to SAM3X8E through the shared serial port using
microUSB port CN6, it is necessary to:
1. Download and install a serial monitor (e.g. Teraterm for Windows, minicom for
Linux, serial tools for OS X). Please check the appendix for the configuration and the
parameters of these software tools.
2. Connect the external host PC through the microUSB port CN6, taking care that
jumper J18 is plugged. Then insert the power plug and start the system.
On the serial monitor now it will appear something like the following:
...

nfc clock : 24000000Hz
