In the NVIDIA Jetson TK1 Unboxing video we open the box in an action packed adventure. Looky here:
The NVIDIA Jetson TK1 Development Kit is built around the Tegra K1, the first supercomputer on a chip. The NVIDIA Jetson TK1 Development Kit is available from Amazon
Jetson connection to USB 3.0 Hub
In the video, you’ll note in passing that I plugged in a USB cable. The other side of that cable is connected to a Plugable 7-Port USB 3.0 SuperSpeed Hub
First time boot
When you boot up the Jetson board for the first time, it goes to a command line prompt. The following instructions are taken from the official Jetson TK1 Support page: README.txt
To install the GUI desktop:
Login using the default account: ‘ubuntu’ and password: ‘ubuntu’
Change directories to the NVIDIA installation directory:
$ cd ./NVIDIA-INSTALLER
Run the installer script to extract and install the Linux driver binary release:
$ sudo ./installer.sh
Reboot the system:
$ sudo reboot
The graphical desktop UI will appear. Remember to only run the installer.sh script once.
We also learned not to leave the camera autofocus on while filming this type of video as during the initial boot process to the command line, the whole scene was nothing but an out of focus hot mess.
Notes on the Jetson Dev Board connectors
If you haven’t been around development boards much, you’ll notice that the Jetson TK1 has a JTAG port on it. The port is extremely useful for hardware development and working with the logic on the board. The JTAG port allows low level access to hardware for testing and other functions such as single stepping and breakpointing. People also use the port to connect an in-circuit emulator to access on-chip debug modules inside the target CPU.
If you’re a software developer who is not writing firmware and someone tells you to access the JTAG port, I suggest that you give them a blank Homer Simpson type of look and tell them that you think the board is most likely broken.
Most of the other ports and slots you’ve probably have seen and have some experience with. Mini-PCIe is common in laptops (a common expansion port for a variety of tasks such as WiFi, Bluetooth, GPS and networking), the SATA connector is where you plug in disk drives and such. The white Molex connector is for powering the SATA peripheral.
The one exception to things that you have seen may be the 125 pin Expansion Port.
The Expansion Port has a large variety of signals available:
- Camera Ports
- LCD Port
- Touchscreen Ports
- HSIC (USB chip-to-chip interconnect)
- I2C (Computer Bus for attaching peripherals)
- GPIO (General Purpose IO)
You’ll need appropriate connectors in order to patch into the signals.
