How to Reinstall the Original File System on Jetson TK1

In case something goes awry while programming the Jetson TK1, you may need to repair the file system on the Jetson TK1. Ramy and I realized we messed something up while trying to follow this guide to install the PS3 Eye on the board. The realization came when we had internet access (via ethernet) but could not connect to the internet or even ping an IP address.

To fix the file system, we followed these steps which essentially is paraphrasing of the steps here from the Linux for Tegra website. I will paraphrase the paraphrasing here for ease of access later.

Materials Needed

1. Linux host PC. There is one in the MicroP's lab available for Jetson. It is the one with non- standard tower. The username is big-Jetson (if I recall correctly). Contact me, Ramy, Da Eun, or Spjut for the password.
2. micro USB to USB cable (should be included with the Jetson TK1 kit)

Steps

1. Prepare the diretory on the host PC

   mkdir tk1_reflash
   cd tk1_reflash
   

2. 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
   

3. 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
   

4. Extract the BSP tarball

   sudo tar xpf Tegra124_Linux_R19.2.0_armhf.tbz2
   

5. Extract the FS tarball into a particular sub directory

   sudo tar xpf Tegra124_Linux_R19.2.0_armhf.tbz2
   

6. 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
   

7. Apply binaries

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

8. 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!
   

9. 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

10. Verify board is connected by running

    lsusb | grep -i nvidia
    

11. You should see the following

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

12. 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
    

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