The Trimslice is one of the most powerful ARM devices available and features a variety of connectivity options. At this time there is no support for a display and the Trimslice boots to a serial console.

Technical Specifications

  • 1 GHz NVIDA Tegra 2 (dual-core ARM Cortex A9)
  • 1 GB DDR2-667 RAM
  • HDMI 1.3 max resolution 1920 x 1080
  • Gigabit Ethernet (Realtek RTL8111DL)
  • 802.11 b/g/n WiFi

Running Fedora on a Trimslice

This page will give you detailed instructions for running Fedora 18 Alpha on your Trimslice. The image is prepared to boot from SD card by default, but can be easily modified to boot from the internal SATA connection (USB) by using the appropriate boot script (boot.scr.usb).

Download the image

The first step is to download the Fedora 18 Alpha image. The prebuilt image includes everything you will need and can be written directly to SD Card, USB, or SATA drive.

Download and verify the checksum:

sha256sum --check Fedora-18-Alpha-armhfp-Images-CHECKSUM

Writing the Image

Linux Users

You can write the image to media of your choosing but it does have to meet the minimum size requirement of 4GB. Connect the media to your computer and make note of the drive. To write the image to your media run the following command, changing the drive to the location of your media.

For the SD Image:
xzcat Fedora-18-Alpha-armhfp-trimslice.img.xz > /dev/<location-of-your-SD-card>

Once completed run the below command to ensure the entire image is written to the device:

For the SATA/USB Image:
xzcat Fedora-18-Alpha-armhfp-trimslice.img.xz > /dev/<location-of-your-SATA/USB>

Then mount the 'boot' partition and copy the appropriate boot script to boot.scr:

 cp boot.scr.usb boot.scr

Once completed run the below command to ensure the entire image is written to the device:


Windows Users

  • You will need to download Win32 Image Writer as well as a tool to extract the image such as 7-Zip.
  • Once downloaded and installed right click on the disk image and select "7-Zip->Extract files here"
  • Launch Win 32 Disk Imager and select the extracted disk image and the device you would like to write the files to. Click "Write". Be very careful during this step - all data on the selected drive will be lost!

Using Fedora on the Trimslice

Connect the newly created media to your Trimslice and power on. No further steps are required and your system should boot to a serial console log in prompt. If you do not have a serial cable to connect your Trimslice, you can watch your DHCP server for the newly connected device. After a few minutes you should be able to see the host "fedora-arm'. Use SSH to connect to the root account.

ssh root@fedora-arm (or IP)

The default root password is "fedora". This should be changed immediately.

Release Notes

  • This test image includes the updates-testing repository enabled by default.
  • Images were composed using tools in Fedora 17 due to continuing work on Fedora 18.
  • When using the images on the Pandaboard and Trimslice the system will automatically reboot twice by default for the following:
    • repartition the root filesystem on first boot. To prevent this delete the '.rootfs-repartition' flag in '/' or by passing a kernel command line argument of 'nofsresize'.
    • The image will automatically be relabeled for SE Linux, this may take some time and will reboot when finished.
