Setup Jetson tk1 -- new instructions

Jetson_tk1_setup2.md

Before you begin, ensure that you've setup network access, either with ethernet or wlan.

Setup timezone

sudo dpkg-reconfigure tzdata

Typically we use "US/Pacific-New"

Mount sdcard

Place sdcard in the slot, with the opencv tegra and cuda files, and edit /etc/fstab

/dev/mmcblk1p1 /mnt/sdcard vfat         umask=000,uid=1000,gid=27 0 0

(This makes the sdcard writable to the ubuntu user.)

Install development packages

First sudo vi /etc/apt/sources.list and uncomment the "universe" lines in order to access universe packages.

# install screen
sudo apt-get install screen
# run screen for the remainder of the install
# this allows you to reconnect if your network connection is lost
screen
# if you lose your network connection, reconnect to the jetson and use:
screen -r

Run the package setup script

• Obtain and run the package setup script jetson_setup_packages.sh using screen.

# Obtain the package setup script
wget https://gist.github.com/tstellanova/6164d0dd621476c0b4b4/raw/6cb4cb9c82a23538c79f1ee77dc4a51a876bb7e5/jetson_setup_packages.sh
chmod +x ./jetson_setup_packages.sh
screen ./jetson_setup_packages.sh

Install prebuilt OpenCV for Tegra

You can download libopencv4tegra and place on your sdcard. Then:

sudo dpkg -i /mnt/sdcard/libopencv4tegra_2.4.8.2_armhf.deb
sudo dpkg -i /mnt/sdcard/libopencv4tegra-dev_2.4.8.2_armhf.deb

Setup git

• Install public / private development keys to ~/.ssh/
• Install a ~/.ssh/ config file

Host bitbucket.org 
 IdentityFile ~/.ssh/id_rsa

Optional: Setup Custom OpenCV build

• Clone our custom opencv repo (opencv-fastcap): git clone git@bitbucket.org:foobarn/opencv-fastcap.git
• Setup custom opencv build

cd opencv-fastcap
mkdir build
cd build
ccmake ..

• Configure required stuff: typically profiling on, debug on, perf tests off, docs off, GigE off , shared libs OFF, build type = RELEASE, cuda_arch = 3.2, clear cuda_arch_ptx, BUILD_FAT_JAVA_LIB off, etc
• 'c' for configure until you see 'g' for generate, then generate and exit
• Build opencv:

# install requires root access
sudo make -j4 install

Because we are building in the native Jetson environment, this can take a half hour or more.

Get other sources

Clone your source repos and go!

Setup keychain

If you're going to be pushing files with git frequently, you'll want to have keychain setup so you won't need to constantly reenter your creds.

• Edit .bashrc

/usr/bin/keychain --lockwait 0 --clear $HOME/.ssh/id_rsa
source $HOME/.keychain/$HOSTNAME-sh

Hints

To find a package, try apt-cache search foo

libopencv4tegra-dev_2.4.8.2_armhf.deb is no longer on the NVidia website. They say " New OpenCV4Tegra runtime packages coming soon " where it should be. Am I missing something?
