Linux SWAP size increase

TODO

~/git/uav_core/miscellaneous/scripts/set_swap.sh

OR

sudo swapoff -a
sudo dd if=/dev/zero of=/swapfile bs=1G count=16
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
grep SwapTotal /proc/meminfo

Disabling automatic sleep/hibernation

OR

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

Change network interface names to the nice ones

TODO

Check UAV core network settings

Disabling network manager

udev rules

Similar to PX4 ROS setup

cd /etc/udev/rules.d

Create a new file (with sudo privileges) and call it 99-usb-serial.rules. Paste this line into the file:

SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="YOUR_DEVICE_DESIGNATOR",OWNER="mrs",MODE="0666"

Replace idVendor, idProduct with you values, and change the OWNER name to your user name. You can use the following utility:

lsusb

Now, if you disconnect and reconnect the device, it should show up as /dev/YOUR_DEVICE_DESIGNATOR. Now you can try

cat /dev/YOUR_DEVICE_DESIGNATOR

and you should see some incoming messages.

Our HW guys have already prepared .rules files for our most used distribution boards and they can be found in

~/git/uav_core/miscellaneous/udev_rules/

so feel free to copy them to your /etc/udev/rules.d folder and (re)use them.

Here are some devices you need to set rules for.

FTDI

RPLidar

Arduino
