How do i get the Zedboard opened up and running?
The Zedboard is here!
It's going to sound weird, I know, but the thing I love the most about Digilent boards is the smell. I've been told it's caused by the board cutting process, but I've never smelled it on any other boards before. mmmm, the smell of endly creativity and knowledge!
Well, let's get the thing opened up!
Zedboard up and running connected to power, Gigabit Ethernet, and the USB COM port
At the time of this blog posting I have Rev B of the hardware. In the event that something changes with Rev C of the hardware I will update this post appropriately.
First things first, read the manual! The link to the Quick Start Guide can be found here:
Download the Getting Started Guide
I highly suggest reading both front to back.
One thing I will note here is that the Getting Started Guide assume that you are running windows Vista or Windows 7. I plan on making an additional blog post on how to get the board up and running under Ubuntu and Fedora.
Now that you have read the manuals from front to back ;p lets get this thing booted up. First we need to ensure that our SD Card is present and installed properly.
A view from the side of the SD Card. It is right below the FMC connector.
The SD Card from underneath the board, note the label is down!
A picture of the SD Card out of the Zedboard, with the lock switch in the disabled position.
Boom, done. Ok, now that we have the SD Card in place we need to setup the Zynq-7000 EPP to boot from it. There are a number of available boot options, as described in the ZedBoard Hardware User's Guide. Download the ZedBoard Hardware User's Guide
Since I know you read it front to back, we'll skip right to the configuration. Your jumpers need to be in this configuration:
JP7 [MODE0] - GND
JP8 [MODE1] - GND
JP9 [MODE2] - 3V3
JP10 [MODE3] - 3V3
JP11 [MODE4] - GND
Here is a picture of my setup:
A picture of JP9 - JP11 setup to boot from the SD Card
The last thing you need to do before you can boot from the SD Card is set JP6 to shorted. This allows the SD Card to be seen by the Zynq-7000 EPP ARM processing core. Here is a picture of my setup:
JP6 Shorted to allow SD Card booting.
Okay, there you have it! Your board is setup to boot from the SD Card, all you need to do is hook up power and your USB cable to the micro USB port labeled UART and after a few seconds you should see Linux start to boot.
For the lazy here are the COM configuration:
115200 8N1
For those who are not privy to the lingo of the UART folk, this means that the UART is running at 115200 bits/second, or baud. The 8N1, commonly pronounced "Eight None One" stands for 8 bits of data, no hardware control, and 1 stop bit. Checkout the UART Wikipedia page here:
http://en.wikipedia.org/wiki/Universal_asynchronous_receiver/transmitter
Now, load up your favorite terminal software (the User's Guide suggests TeraTerm if you are on a windows machine) and set the COM port appropriately with the above settings and you should be good to go. If you see this:

You are good to go! Congrats!
