I followed the link listed in my last post and decided to use the J20 EDBG-USB connector to "talk" to the board. So I clicked on the link labeled
"Install USB drivers for Atmel and Segger tools"
and landed on the download page for the Atmel USB installer. The page had a warning that a newer version of the download was available and a new link:
"A newer version of this product is available. Click here to see the details."
So, I clicked on the new link which brought up a nearly identical page only with a newer version number, 7.0.666. I clicked on the download button, signed in to my Atmel account, and downloaded the driver installer "driver-atmel-bundle-7.0.666.exe".
After successfully installing this driver package, I downloaded putty to use as a terminal emulator. The current download page for this utility is here: PuTTY Download Page. I downloaded and installed "putty-0.63-installer.exe".
On my board at least the jumper JP1 was already opened, so I didn't have to do anything there although the instructions said to open it.
From there I plugged the provided USB cable into the EDBG-USB micro-A USB port on the board and plugged the opposite end into my PC (running Windows 7 Pro). The board was enumerated as COM4 on my machine as I found by opening the device manager (from the control panel) and searching for the port labeled "EDBG Virtual COM Port".
After this was complete, I was able to open putty using the com port and the specified settings and bring up a terminal window:
Not seeing anything come up in the terminal window, I pressed reset on the board and viola! The boot messages for the Linux system scrolled across the screen. I've attached a text file with the boot messages for your reading enjoyment. Note that I didn't have to download anything to the board to get to this point. The Linux OS was preloaded on the board when I received it.
