Installation instructions

This installation requires the Google Chrome browswer and a micro-USB Cable.

  1. Download the firmware listed above.

  2. Visit https://electro-smith.github.io/Programmer/ in the Google Chrome browser.

  3. Connect the loop module to your computer via USB. The module does not need power from the rack for an update. The power supplied by the computer is enough.

  4. Reboot the loop by pressing the “boot” and “reset” buttons on your loop, in that order, then release both.

  5. Press the “Connect” button on the web programmer tool and a list of devices to connect to will appear. If your loop is ready, you will see “DFU in FS Mode” as an option.

  6. Choose “DFU in FS Mode” and press the “Connect” button.

  7. Under “or select a file from your computer”, click “Choose File” and find loop firmware file on your computer. The naming convention for loop firmware is “jroo-loop-xxx.bin” where xxx is the version number.

  8. Once the firmware is selected, click “Program” in the Programming Section and the loop will begin to update. If successful, “Done!” will appear on the screen and the lights on the loop will be alternating slowly, ready for the initial recording.

  9. If the module isn’t connected to your rack’s power, reconnect it and add it back to your rack.
