I am testing with the last version of Armbian (Ubuntu Bionic) and it's working fine.
i2c-1 is enabled by default.
sudo apt install python3-wheel python3-setuptools python3-dev build-essential sudo apt install python3-smbus git clone --depth 1 https://github.com/rm-hull/luma.oled git clone --depth 1 https://github.com/rm-hull/luma.examples cd luma.oled/ sudo -H python3 setup.py install cd ~/luma.examples/examples python3 welcome.py
Don't forget to add yourself in the "i2c" group and to connect your oled in the P27 (i2c1-sda) and P28(i2c1-scl) and 3.3volts.
sudo usermod -aG i2c your-login

Yes, I have Rock64 working with I2C and a 20x4 LCD display like this one
and the dbrgn/RPLCD under Python 3.6.6 (Ubuntu Bionic 18.04) :
git clone https://github.com/bazooka07/RPLCD.git -b test-entrypoint-1811 ( I fix a little bug for the test )
I have too an ESP8266 (Nodemcu) and a OLed 0.96" display. I'm trying for running Oled with Rock64.
The following library is working but don't keep the display on when I leave my script
pip3 install luma.oled
My script :
#!/usr/bin/env python3 from luma.core.interface.serial import i2c, spi from luma.core.render import canvas from luma.oled.device import ssd1306 serial = i2c(port=1, address=0x3C) device = ssd1306(serial) with canvas(device) as draw: draw.rectangle(device.bounding_box, outline='white', fill='black') draw.text((30, 40), 'Hello World', fill='white')
Don't forget to connect on i2c-1 pin #27 (sda) and pin #28 (scl) unlike RPI3

Useful doc here :
http://synfare.com/599N105E/hwdocs/rock64/index.html
I am trying with Ayufan distribution :
I have connecting i2c on P27 (i2c1-sda) and P28(i2c1-scl) and 3.3volts and the display is found with "i2cdetect -y 1" on 0x3f.
Now, I have to install lcdproc

I have a Rock64 powered by Armbian version 5.60 kernel 4.4.162-rockchip64 Ubuntu Bionic
How can I activate i2c0 and i2s0 ports for connecting a 16x2 characters LCD display like 1602LCD and a PCM5102 DAC ?
I'm trying armbian-config and I'm reading https://docs.armbian.com/User-Guide_Allwinner_overlays/ but I'm getting no help.
Thanks for advance.

Hello,
Each time I'm booting the Rock64, it starts on Jan, 21 of 2016 but the filesystem has a superblock on Jan,28 of 2018, so in the future.
It's inconsistant and the filesystem is checking each time and I'm waiting a few seconds. How can I avoid this trouble ?
Here is the screen shot of logs through the tty/usb console. I'm booting from the spi flash and a sd-card with Ubuntu 18.04.1.
QuoteBegin: Will now check root file system ... fsck from util-linux 2.31.1
[/sbin/fsck.ext4 (1) -- /dev/mmcblk1p1] fsck.ext4 -a -C0 /dev/mmcblk1p1
ARMBIAN-BIONIC: Superblock last mount time (Sun Jan 28 15:58:17 2018,
now = Thu Jan 21 08:50:18 2016) is in the future.
FIXED.
ARMBIAN-BIONIC: 39110/988000 files (0.1% non-contiguous), 314286/4096000 blocks
done.
done. -
