Miscellaneous tips for RPI like board

[khancyr]

Hi,

Here are some tips about performance and usability on card like rpi, odroid etc !

Give permission on external port

Add user to dialout and video group

For permission with udev rules
sudo nano /etc/udev/rules.d/50-myusb.rules

KERNEL=="ttyUSB[0-9]",MODE="0666"
KERNEL=="ttyACM[0-9]",MODE="0666"

Install new Irqbalance as sometime an old version is given or no version at all

Follow https://github.com/Irqbalance/irqbalance

Install cpufrequtils and use performance on all core

sudo apt-get install cpufrequtils
sudo sed -i 's/^GOVERNOR=.*/GOVERNOR="performance"/' /etc/init.d/cpufrequtils

Reduce swapiness on system on sd card

sudo nano /etc/sysctl.conf
sysctl vm.swappiness=10

Use Dash instead of Bash for less ram comsume, and faster cmd. And pretty transparent for normal task

sudo apt-get install dash
sudo dpkg-reconfigure dash

Various Optimisations

Removal of /dev/tty 2 à 6 -> RAM ++

Probably must be adapted this is on odroid + ubuntu

sudo nano /etc/default/console-setup

modify : ACTIVE_CONSOLES="/dev/tty[1-2]"
Edit /etc/systemd/logind.conf and change value of NAutoVTs

To see the number of active term :

ps a | grep tty

Terminal removal :
To disable console 3 , you can rename the file /etc/init/tty3.conf to /etc/init/t_t_y_3.conf.OLD (for example).

sudo mv /etc/init/tty3.conf /etc/init/t_t_y_3.conf.OLD

Other solution, look at inittab to remove them
sudo su

sed -i '/[2-6]:23:respawn:/sbin/getty 38400 tty[2-6]/s%^%#%g' /etc/inittab

Purge system from unused default crap : apache, nodejs, cups, x11 etc. etc and reach 5s boot time ! ^^ (could give the list for odroid c1 if need)

I would like the Odroid 3 list please.

Purge uninstalled packages

sudo dpkg --list | grep ^rc | awk -F" " ' { print $2 } ' | xargs apt-get -y purge
sudo apt-get install deborphan 
sudo apt-get autoremove --purge $(deborphan)

SSH Server Keys are not regenerated upon first boot

udev rules for network devices aren’t purged before the image is created. This causes the main ethernet interface to get listed as eth1 instead of eth0
NetworkManager is installed. You’ll need to edit /etc/network/interfaces, then disable NetworkManager, then go with this.

Regenerate SSH KEYS

sudo rm /etc/ssh/ssh_host*
sudo dpkg-reconfigure openssh-server

Fix Udev

sudo su
echo > /etc/udev/rules.d/70-persistent-net.rules
reboot
