Image Setup¶
- Download the latest version of the image file.
- Unzip the file (the extension should be

Linux¶
(These instructions have not been recently tested.)
- Find the device name for your SD card. This can be done by using the
lsblk
command before and after plugging in the SD card; the new device is the card. It will look something like/dev/name
. - Unmount it with
umount /dev/name_of_sd
. - Open a terminal and navigate to the folder containing your image (it is probably in downloads, so on a fresh terminal
cd Downloads
should work). - Finally, begin the copy process with
sudo dd bs=1M if=name_of_image.img of=/dev/name_of_sd status=progress
. The image is 128 GB.

Creating an Account¶

- Set a new username and password for the router login, and make sure to set a password for the Wi-Fi.
Connecting a RACECAR-MN¶
For each car you want on this network, you must do the following:
- On the car, connect to your newly created network.
- Under network settings on the car, click the checkbox enabling the “allow for all users” connection option, this will ensure the car connects without needing you to login first.
- Also make sure to tell the car to connect to your network automatically.
- Once connected, type
ifconfig
, find the entry for Wi-Fi (it should be “wlan0” or “wlo1” or something else starting with a w), and after that find a 12-digit alpha-numeric code delimited by colons (it should look liked0:53:7a:bf:01:a6
or something similar, notff:ff:ff:ff:ff:ff
). This is called the MAC address. - On the router’s online portal, navigate to the DHCP settings page.
- Add a reserved address for the car of
192.168.1.###
