RACECAR-MN Software Setup

This page will walk you through the steps needed to set up the operating system of a RACECAR-MN.

Image Setup

  1. Download the latest version of the image file.
  2. Unzip the file (the extension should be .img not .zip).
  3. Find a computer that has an SD port, and plug in the micro-SD card in the SD adapter.

The operating system of your computer has will determine your next steps.

Linux

  1. 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.
  2. Unmount it with umount /dev/name_of_sd.
  3. 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).
  4. 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.

Mac

  1. Find the device name of your SD card with diskutil list. It should be labeled with the (external, physical) tag. The name will look something like /dev/name.
  2. Unmount it with diskutil unmountDisk /dev/name_of_sd.
  3. 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).
  4. Finally, begin the copy process with sudo dd bs=1M if=name_of_image.img of=/dev/name_of_sd status=progress; sync. The image is 128 GB.

Router Setup

Creating an Account

  1. Once you plug in your router and turn it on, go into a browser and type into the address bar 192.168.1.1
  2. This should present you with a login page, type in the default username and password for the router. If you are not sure, try “admin” for both.
  3. 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:

  1. On the car, connect to your newly created network.
  2. 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.
  3. Also make sure to tell the car to connect to your network automatically.
  4. 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 like d0:53:7a:bf:01:a6 or something similar, not ff:ff:ff:ff:ff:ff). This is called the MAC address.
  5. On the router’s online portal, navigate to the DHCP settings page.
  6. Add a reserved address for the car of 192.168.1.### where ### is your chosen 3 digit car number. Put the MAC address mentioned before where prompted, and make sure you click enable and apply.
