Console Connection
The console is a simple text-based user
interface that allows many clock settings to be
adjusted and tested. It is an imported debug
tool when writing Nuggle programs. The
console hardware is also the SAM3X8C
programmer.
The SAM3X8C programmer
The programmer is plugged into the Fortress
E1T clock processor plug-in board using a 6-
way ribbon cable and IDC connector. Plug the USB mini connector into a computer USB port
using a suitable cable. The tests here that rely on the computer assume you are using a PC with
Windows 10 installed. I cannot cover other operating systems as I have neither a Linux or MAC
system.
The PC should enumerate the board and a
standard serial device interface installed. Look
in the Device Manager and under the Ports
(COM & LPT) a new USB Serial Device (COMxx)
should have appeared. Where COMxx will be
replaced by the COM port now assigned. Note
the number as it will be needed later. In my
case the port number was COM9. If you are
uncertain which USB Serial Device has just
appeared (you may have others) then
disconnect and reconnect the board and look
for the device that disappears and then
reappears.
Warning!
When using the programmer as a
console connection be careful not to
accidentally press the “Erase” button or else
you will erase the flash contents of the
SAM3X8C. Not the end of the world but
probably a nuisance as you will need to re-flash
the SAM.
You should also see the power LED D1 next to
the USB min connector glowing. If you look
carefully, then you will see the SAM connection
LED D6 next to the ribbon cable connector
glowing as some power bleeds through to it.
Run a serial console program - I often use Tera
Term . Set the serial port to the COM number
you noted in step 1 above. Configure the serial
