Hey guys,

I’ve been working on setting up the Jetson TK1 development board to get it ready for some motion control fun. Here are some notes documenting what I've done.

Accessing the Board

To access the board, you can do so directly, or you can do so remotely through an Ethernet port. I chose to use direct access since I only have one Ethernet cable and didn’t want to set up a DHCP server on my Windows laptop. So I hooked up the board to HDMI display, got a usb hub (thanks Sky!), and attached a mouse and keyboard.

Preparing GUI Desktop

The first thing I did was set up the GUI desktop. The README instructions are found under ${HOME}/NVIDIA-INSTALLER. Basically, you just run the installer script using the command sudo ./installer.sh And then you reboot the system and the GUI should load. You only need to run installer.sh once.

Links

I met up with Ramy and we worked together to get familiar with the board. This is just a compilation of the links used so they are all in the same place.

*You should definitely check out the sample simulations. Those are fun.

• Note that if when you try to compile HOG with the instructions they give you:

g++ hog.cpp -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_calib3d
-lopencv_contrib -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_legacy 
-lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_photo -lopencv_stitching 
-lopencv_superres -lopencv_video -lopencv_videostab -o hog

You will get an error that says “cannot find -lopencv_nonfree.” Run the compiler instructions without that instructions (so just delete it) since that it from an old version of the code. The dependency is no longer needed.

If you try to run

./hog --video 768x576.avi

You won’t see the graphical output. You need to install plugins to play media files of following type: DivX MPEG-4 Version 3 Decoder.

Follow README.linux.

I also met up with Da Eun in order to pick up the Playstation Eye webcamera. In order to interface the Playstation Eye with the board, there's a somewhat involved process that needs to followed:

Guide to installing Playstation Eye

I am currently in the process of rebuilding the kernel in order to get this guide to work (the first step in the tutorial listed above). However, I am having trouble configuring the kernel (specifically with the command “make menuconfig” from part(c) of this tutorial).

In the meantime, I’ve also been looking into the sample code used in the Full-Body Detection tutorial in order to figure out how it can be customized to our needs.

I'm also going to try to get the Full-Body Detection tutorial/webcam to work on my laptop so I can work on the code even without the board.
