jn-scripts

Who does what ?

• jn_sd_resize.sh resizes the SD card partitions to use all instead of the original 16GB. (Tested of JetPack4.3). Thanks to this post on nvidia dev forum.
• create_8Gswap.sh, creates an 8GB swap memory on disk. Pretty practical for installation. Thanks to this post.

Reminders

• To use the GPIO remapping tool, run this once sudo find /opt/nvidia/jetson-io/ -mindepth 1 -maxdepth 1 -type d -exec touch {}/__init__.py \ before running this sudo /opt/nvidia/jetson-io/jetson-io.py
• Default python is linked to python2, unlink python2 and link python3 by default.

Resources

• Power your board through the barel jack so you can have the best performances (don't forget to run sudo nvpmodel -m 0). See this video.

• You can connect to the board without screen keyboard and mouse

  • Using USB to TLL cables. See this post for more instructions for that.
  • Through USB. Connect the board using te barrel jack. Connect USB to your host with screen /dev/ttyACM0 115200. I prefer using tio, it handles colors better and I can still use Ctrl + A. The command looks like tio /dev/ttyACM0 --baudrate 115200. Consider using termsize to exploit the terminal size fully over serial terminal.
  • Through SSH, connect the board to wifi, get IP adress (with ifconfig for example) and run ssh <username>@<ipadress>

• Nice post about the Nano in general, sets up remote desktop.

• Device tree overlays to reconfigure the 40-PIN GPIO header here

• Build kernel and modules locally after building, video here.

• Pisound support for Tinkerboard, see here.

Tools

• jtop is nice to monitor GPU usage. Install with sudo -H pip install jetson-stats. See here.

Installing

• Tensorflow, instructions here.
• Soundcard :

sudo apt install libffi-dev python-cffi
sudo pip install soundcard
