The console port provides an FT232 USB to serial converter connected to /dev/ttyO2 of the Linux running on the Pyra. This allows to watch boot messages from MLO, U-Boot and the Kernel. So the external device must be an USB host and this port is just an USB slave. But you might need some FTDI driver to access the FT232 as a serial port (/dev/tty$something) on your host.To "telnet" into the Pyra you just have to answer the login: and passwd: prompts presented by getty.What is the difference between a host port and a console port? How do you use a console port? Can you connect it to some other computer and somehow get a Pyra tty? (if so, what would be the command to "telnet" into the Pyra like that?)
The reason to choose this solution is that we wanted to have a separate charger input (to allow the USB3 port to be switched to host mode). Therefore we already had a need for a standard socket (micro-USB).This allows to connect the Pyra to some off-the-shelf charger or notebook.
Adding the FT232 chip and connecting it to the UART port of the OMAP was quite obvious to do. Basically it replaces an external RS232 converter for the expansion port of the OpenPandora.
