roboRIO 2.0 microSD Card Imaging

Nota

The imaging instructions for the NI roboRIO 1.0 are here.

The NI roboRIO 2.0 boots from a microSD card configured with an appropriate boot image containing the NI Linux Real-Time OS, drivers, and libraries specific to FRC. There are two ways to create the microSD card – with the roboRIO using the imaging tool, or with a laptop and an SD burner application per the instructions on this page.

Importante

The first time a roboRIO 2 is imaged (or if the microSD card is replaced with a new card), the microSD card must be imaged using these instructions; imaging the roboRIO 2 directly with the roboRIO Imaging Tool is not supported.

microSD Requirements

The NI roboRIO 2.0 supports all microSD cards. It is recommended to use a card with 2GB or more of capacity.

Operation Tips

The NI roboRIO 2.0 requires a fully inserted microSD card containing a valid image in order to boot and operate as intended.

If the microSD card is removed while powered, the roboRIO will hang. Once the microSD card is replaced, the roboRIO will need to be restarted using the reset button, or be power cycled.

No damage will result from microSD card removal or insertion while powered, but best practice is to perform these operations while unpowered.

Imaging Directly to the microSD Card

The image will be transferred to the microSD card using a specialized writing utility, sometimes called a burner. Several utilities are listed below, but most tools that can write arbitrary images for booting a Raspberry Pi or similar dev boards will also produce a bootable SD card for roboRIO 2.0.

Supported image files are named FRC_roboRIO2_YEAR_VERSION.img.zip. You can locate them by clicking the SD button in the roboRIO Imaging tool and then navigating to the SD Images folder. It is generally best to use the latest version of the image.

If using a non Windows OS you will need to copy this image file to that computer.

Click the SD folder icon will bring up the location of the images in windows explorer.

A microSD to USB dongle works well for writing to microSD cards.

Nota

Raspberry Pi images will not boot on a roboRIO because the OS and drivers are incompatible. Similarly, a roboRIO image is not compatible with Raspberry Pi controller boards.

Writing the image with balenaEtcher

  • Download and install balenaEtcher.

  • Launch

  • Flash from file -> locate the image file you want to copy to the microSD card

  • Select target -> select the destination microSD device

  • Press Flash

Writing the image with Raspberry Pi Imager

  • Download and install from Raspberry Pi Imager.

  • Launch

  • Choose OS -> Use Custom -> select the image file you want to copy to the microSD card

  • Choose Storage -> select the destination microSD device

  • Press Write

Advertencia

After writing the image, Windows may prompt to format the drive. Do not reformat, or else you will need to write the image again.

Setting the roboRIO Team Number

The image writing process above does not set a team number. To fix this teams will need to insert the microSD card in the robRIO and connect to the robot. With the roboRIO Imaging Tool go to Edit Startup Settings. Next, fill out the Team Number box and hit Apply.

The edit Startup Settings portion of the imaging utility allow a team to renumber their robot.
