If you want to try the experimental 64 bit ARM, here's the steps needed....
First extract Arduino
Code:
tar -xvf arduino-1.9.0-beta-linuxaarch64.tar.xz
Uncompress and run the Teensyduino installer. The normal UPX compression isn't working yet, so for now it comes xz compressed.
Code:
unxz TeensyduinoInstall.linuxaarch64.xz
chmod 755 TeensyduinoInstall.linuxaarch64
./TeensyduinoInstall.linuxaarch64
Install the Teensy udev rules, as you would on any Linux system
Code:
wget https://www.pjrc.com/teensy/49-teensy.rules
sudo cp 49-teensy.rules /etc/udev/rules.d/
Unfortunately the Oracle JRE with Arduino is "Headless" (doesn't support graphics yet on ARM 64 bit?), so it must be deleted. Install the OpenJDK JRE instead.
Code:
cd arduino-PR-beta1.9-BUILD-69
rm -rf java
sudo apt-get install openjdk-8-jre
Arduino's "builder" program (written in Google Go language) is still 32 bits, so the 32 bit C libraries need to be installed.
Code:
sudo dpkg --add-architecture armhf
sudo apt-get update
sudo apt-get install libc6:armhf libstdc++6:armhf
Optional: nVidia Jetson TX2 ships with a kernel lacking the cdcacm driver (USB Serial). You could try installing this to get it. Fortunately Teensy uses HID for programming and has HID-based serial emulation for non-serial modes, so you don't absolutely need this to use Teensy. It is needed for all normal Arduino boards.
Now you're ready to use Arduino.
Code:
./arduino
Select Teensy in Tools > Boards menu
Select RawHID in Tools > USB Type menu
Open File > Examples > 01.Basics > Blink
Click Upload
(press button on Teensy... needed if prior program to USB Serial)
Here's a photo of the setup on my desk right now, with the Teensy 3.6 freshly programmed by the Jetson TX2.
