How do I update CHOMPI's Firmware?

Created by CHOMPI Support, Modified on Fri, 19 Jul at 10:14 AM by CHOMPI Support

Update Instructions:

Step 01: Turn off CHOMPI if not already off

You should never try to remove the microSD card from CHOMPI while it is powered on

Step 02: Remove microSD Card from CHOMPI

Carefully remove the microSD card from the slot located on the right side of the rear panel (next to the handle)
TIP: The slot is designed with a round hole in the center that nicely fits a 3.5mm cable end, ballpoint pen or something similar
NOTE: The card is spring loaded so watch for any flying SD cards ;)

Step 03: Insert microSD Card into your Computer

Using a standard microSD card adapter, load the card onto your computer just like any other external hard drive or storage device

Step 04: Backup your files (Optional, but recommended)

Now is a great time to take a second and backup your files and presets that are currently being stored on the card
It’s good practice to select all of the files on in the root directory of the card, and simply copy them into a new folder on your computer

Step 05: Erase old firmware file

Move the old firmware file from the SD card into the trash of your computer. It will be named something like: “CHOMPI_V1_0_6.bin”
Remember to “empty the trash” of your computer before moving to the next step

Step 06: Copy New Firmware onto SD Card

Move/Copy the new firmware file that you wish to use with CHOMPI onto the root directory of the SD card (NO FOLDERS)
Remember... No Duplicate Firmware Files

Step 07: Eject microSD card from your computer

Step 08: Reinstall microSD Card Back into CHOMPI

Carefully reinsert the microSD card back into CHOMPI
- WARNING: due to the way the panel enclosure is designed, it is possible to miss the card slot and drop your SD card into the enclosure. If this happens, simply remove one of the side panels and shake the SD card out

Step 09: Power On CHOMPI and Enjoy the LED Lightshow

We recommend plugging in CHOMPI to a USB power source for this next part.

Flip the power switch towards the lightning bolt icon to boot up CHOMPI
Wait for the LED animation to complete
- Every time CHOMPI boots up, it checks the SD Card to verify the firmware. If it recognizes a new firmware file, it will automatically launch the firmware updater (this is indicated by the first LED “glowing” animation on bootup)
- Typically, this process should only take 15-30 seconds
- Once you see the “rainbow” animation on the LED’s, you should be good to go!
- NOTE: if CHOMPI does not recognize the SD card when it boots up, the upper row of LEDs will blink RED. If this happens, power off the device, re-insert the SD card and try again

Your CHOMPI should now be updated and running the newest firmware!
