Ubuntu_16.04
Ubuntu 16.04 is supported only for UP Board, UP Core, UP Squared, and UP Core Plus. If you need an OS for UP Xtreme or newer boards, please refer to the Ubuntu 18.04 page.
- a UP, UP2, UP Core, or UP Core Plus board
- a USB stick with at least 8Gb of space
- Keyboard, mouse, a screen and an internet connection
- Download Ubuntu 16.04.7 ISO from the Ubuntu download page (works with desktop and server edition)
http://releases.ubuntu.com/16.04/ubuntu-16.04.7-desktop-amd64.iso
http://releases.ubuntu.com/16.04/ubuntu-16.04.7-server-amd64.iso
- Burn the downloaded image on a USB stick. We suggest using etcher for doing that. You can download it from,
https://etcher.io
- Insert the USB installer disk in an empty USB port and proceed with a normal Ubuntu installation.
- While installing, do not select the option "automatic updates"
After the reboot you need to add our repository:
sudo add-apt-repository ppa:aaeon-cm/up
Update the repository list
sudo apt update
Remove all the generic installed kernel
sudo apt-get autoremove --purge 'linux-.*generic'
Install our kernel (we use suffix 18.04 because the kernel is valid and built for both Ubuntu 16.04 and 18.04):
sudo apt-get install linux-image-generic-hwe-18.04-upboard
Install the updates (please make sure to not upgrade the system to Ubuntu 18.04):
sudo apt dist-upgrade -y
sudo update-grub
Reboot
sudo reboot
After the reboot you can verify that the kernel is indeed installed by typing
$ uname -a

Download the next debian packages from our Launchpad site listing the archives inside linux-hwe - 4.15.0-37.40~upboard07:
https://launchpad.net/~aaeon-cm/+archive/ubuntu/up/+packages
linux-headers-4.15.0-37_4.15.0-37.40~upboard07_all.deb
linux-headers-4.15.0-37-generic_4.15.0-37.40~upboard07_amd64.deb

linux-source-4.15.0_4.15.0-37.40~upboard07_all.deb
Then, copy all the .deb files to your USB stick and connect to the USB port on your board.
Remove all the generic installed kernel
sudo apt-get autoremove --purge 'linux-.*generic'
To install the kernel locally you have to go to the directory where you saved the debian packages. There, just run the dpkg command to install all packages together:
sudo dpkg -i *.deb
Once the installation is done successfully, be sure the GRUB is updated to include the newst kernel:
sudo update-grub
Finally, reboot your machine and check your new kernel installed:
sudo reboot
uname -a

This firmware is available for UP Core (AP6214A chipset) and UP Core Plus (AP6355 chipset).
Just run the next command:
sudo apt install firmware-ampak
Reboot your machine to get the firmware working:
sudo reboot
First of all, you may need to connect a WiFi antenna to your UP Core board [ANT1 connector].
Check the UP Core connectors in https://downloads.up-community.org/download/up-core-connectors-description/.
Scan your available WiFi networks:
sudo iwlist wlan0 scan
You will see all the WiFi interfaces in your area.
Check your Bluetooth devices in your area:
hcitool scan
Download the next debian package from our Launchpad site listing the archives inside firmware-ampak - 1.2.0-0:
https://launchpad.net/~ubilinux/+archive/ubuntu/up/+packages
firmware-ampak_1.2.0-0_all.deb
Then, copy the .deb file to your USB stick and connect to the USB port on your board.
To install the Ampak firmware locally you have to go to the directory where you saved the debian package. There, just run the dpkg command to install the package:
sudo dpkg -i *.deb
Reboot your machine to get the firmware working:
sudo reboot
Scan your available WiFi networks:
sudo iwlist wlan0 scan
You will see all the WiFi interfaces in your area.
Check your Bluetooth devices in your area:
hcitool scan
To enable support on Ubuntu for WiFi when using our UP WiFi Kit 5M02.B module, please follow the steps available on the readme of our GitHub repository: Add WiFi/BT support for 5M02.B
On Recent Ubuntu images the HDMI Audio configuration is broken. Once the installation of Ubuntu is complete from the terminal you can run this command to fix it:
sudo sed -i '/module-detect/ {n;a\
## fix HDMI audio on Intel Cherry Trail platforms with latest Ubuntu releases\
unload-module module-alsa-card\
load-module module-alsa-sink device=hw:0,2
}' /etc/pulse/default.pa
Once the system is rebooted the HDMI audio will work automatically.
To be able to use the GPIO, PWM, SPI, I2C, and UART functionality with a normal user we need to set the correct permission.
NOTE: this could create a security problem, do only if you know what are you doing
Run the following command to install the upboard-extras package:
sudo apt install upboard-extras
The command will add rules.d file as follows. The step is necessary.
/lib/udev/rules.d/99-gpio.rules
/lib/udev/rules.d/99-i2c.rules
/lib/udev/rules.d/99-leds.rules
/lib/udev/rules.d/99-spi.rules
/lib/udev/rules.d/99-ttyAMA0.rules
You can create a bash script (e.g. permissiongroups.sh) script with the following content:
#!/bin/sh
set -e
for group in gpio leds spi i2c; do
if ! getent group $group >/dev/null; then
addgroup --system $group
fi
done
Then add execution permissions
($ chmod +x permissiongroups.sh)
and run it ($ ./permissiongroups.sh)
You need to add the user that needs to access the HAT functionality to the corresponding groups:
for example, this command permits the current user to access the GPIO functionality
sudo usermod -a -G gpio ${USER}
LEDs
sudo usermod -a -G leds ${USER}
SPI
sudo usermod -a -G spi ${USER}
I2C
sudo usermod -a -G i2c ${USER}
UART
sudo usermod -a -G dialout ${USER}
to apply the permission changes after issuing the previous command a reboot is needed
sudo reboot
Hang on shutdown or reboot with certain Kernel releases. This is a problem related to kernel modules for HSUART DMA support that get loaded on Cherry Trail SoC, used by UP Board and UP Core.
The HSUARTs can still be used in PIO mode even after disabling DMA support but will be less CPU efficient.

edit /etc/modprobe.d/blacklist.conf and add lines to the bottom
blacklist dw_dmac_core
