Set up a new Jetson TK1

For this class, I recommend using the most up-to-date version of the Grinch Kernel. These instructions are based on this post.

Materials Needed

Linux host PC. The machines in the MicroPs lab all can boot into Linux.
Jetson TK1 board.

Steps

Prepare the diretory on the host PC
```
mkdir tk1_reflash
cd tk1_reflash
```

Get Jetson TK1 board support package aka BSP (called Tegra124LinuxR19.2.0_armhf.tbz2)

wget https://developer.nvidia.com/sites/default/files/akamai/mobile/files/L4T/Tegra124_Linux_R19.2.0_armhf.tbz2

Get sample file system file (called TegraLinuxSample-Root-FilesystemR19.2.0armhf.tbz2)

wget https://developer.nvidia.com/sites/default/files/akamai/mobile/files/L4T/Tegra_Linux_Sample-Root-Filesystem_R19.2.0_armhf.tbz2

Extract the BSP tarball

sudo tar xpf Tegra124_Linux_R19.2.0_armhf.tbz2

Extract the FS tarball into a particular sub directory
```
sudo tar xpf Tegra124_Linux_R19.2.0_armhf.tbz2
```

Extract the FS tarball into a particular sub directory

cd Linux_for_Tegra/rootfs
sudo tar xpf ../../Tegra_Linux_Sample-Root-Filesystem_R19.2.0_armhf.tbz2

Apply binaries

cd ..
sudo ./apply_binaries.sh
The following output will be seen:

Expect to see this

Using rootfs directory of: /home/you/tk1_reflash/Linux_for_Tegra/rootfs
Extracting the NVIDIA user space components to /home/you/tk1_reflash/Linux_for_Tegra/rootfs
Extracting the NVIDIA gst test applications to /home/you/tk1_reflash/Linux_for_Tegra/rootfs
Extracting the configuration files for the supplied root filesystem to /home/you/tk1_reflash/Linux_for_Tegra/rootfs
Creating a symbolic link nvgstplayer pointing to nvgstplayer-0.10
Adding symlink libcuda.so --> libcuda.so.1.1
Extracting the firmwares and kernel modules to /home/you/tk1_reflash/Linux_for_Tegra/rootfs
Installing the board *.dtb files into /home/you/tk1_reflash/Linux_for_Tegra/rootfs/boot
Success!

Write to eMMC over USB. Hold "RECOVERY" buttom on board and press "RESET" button once on board. This puts the board in recovery mode. Connect host computer to target board through USB
Verify board is connected by running
```
lsusb | grep -i nvidia
```

You should see the following

Bus 002 Device 004: ID 0955:7140 NVidia Corp.

Run the following.

sudo ./flash.sh -S 14580MiB jetson-tk1 mmcblk0p1

But if that doesn't work run

sudo ./flash.sh -S 8GiB jetson-tk1 mmcblk0p1

This should print something similar to the following. It will take a while to run.

See this link for some post-install housekeeping. My recommended post-install steps are as follows:

Prevent updates from overwriting graphics drivers
```
sudo apt-mark hold xserver-xorg-core
```

Add universe to repository source

sudo apt-add-repository universe
sudo apt-get update

(Optional) Upgrade installed packages (could take a little while)
```
sudo apt-get upgrade
```
(Optional, but nice) Set up command-line tab completion
```
sudo apt-get install bash-completion command-not-found
exit
```
They say you need to reboot for this to work...

(Optional, but nice) Remove stupid suggestions from Unity

gsettings set com.canonical.Unity.Lenses disabled-scopes "['more_suggestions-amazon.scope', \
'more_suggestions-u1ms.scope', 'more_suggestions-populartracks.scope', 'music-musicstore.scope', \
'more_suggestions-ebay.scope', 'more_suggestions-ubuntushop.scope', 'more_suggestions-skimlinks.scope']"

Other comments

I was able to get this to work using the Board Support Package and Sample File System for release 21. Your mileage may vary, but I recommend using the newer version if it works.

There's also a newer version of the Grinch Kernel for release 21, but I haven't tested it.

There's a potential solution to HDMI audio issues.

The original version of these instructions was written by Amy Ngai and Ramy Elminyawi.

"To fix the file system, we followed these steps which essentially is paraphrasing of the steps here from the Linux for Tegra website."
