Instructions for Updating the gFEX OS

Note: If possible it is always good to use a new SD card, so we have a version of the OS that definitely works in case of problems.

OS Files
CERN Board: https://cernbox.cern.ch/index.php/s/d6SJ6Lt9QExfo0V
BNL Board: https://cernbox.cern.ch/index.php/s/9uKKZcDDGM3PESI

  • Download the tar files attached to this release and extract them to your machine
  • Turn off the board and remove the current SD card.
  • Plug the SD Card into a windows computer using an SD card reader
  • If possible, eject this SD Card and insert a new SD card so we have a backup of the OS. Otherwise continue with the current SD Card.

Using Terminal:

  • Go to the terminal and navigate to the location of the core-image-gfex-gfex-prototype4.wic
  • In the terminal run diskutil list to find the same of your SD card. It should look something like /dev/diskN.
  • Then rundiskutil unmountDisk /dev/diskN where /dev/diskN is the name of your SD card/ This will unmount the SD card from the filesystem.
  • Then run dd if=core-image-gfex-gfex-prototype4.wic of=/dev/rdiskN bs=1m This command will flash the image to the SD card. It will take a *little time, and there's absolutely no output until it completes, so don't be worried if you don't see anything.
  • Remaining instructions below Windows instructions

For Windows/Mac/Linux:

  • Open balenaEtcher (Can be downloaded here: https://www.balena.io/etcher/)
  • Make sure the SD card is selected as the device
  • Click the select button and locate the core-image-gfex-gfex-prototype4.wic file. Make sure "All Files" is selected in the file type options box in Windows Explorer, otherwise the .wic image may not show up.
  • The Rufus settings should automatically be fine. Double check that your SD card is selected as the device, and select the .wic image as the Boot selection.
  • Click start, and wait for the process to complete.

General Finishing Instructions:

  • When balenaEtcher or the dd command has finished, copy the BOOT.BIN from the tarball you downloaded earlier to the SD Card
  • Copy the system.dtb from the tarball you downloaded earlier to the SD Card with the updated OS.
  • Eject the SD card from the computer.
  • Plug the SD card into the board, and the board should now boot with the updated OS.
