Flashing the display - Phil1988/FreeDi GitHub Wiki

This is only necessary if you manually want to flash the display or you are on a firmware up to v1.03. Later versions have an auto update mechanism for the screen firmware included and manual flashing has no benefit.

To flash the display firmware, you will need a FAT32 formatted sd card.

To flash the firmware:

1. Take the matching firmware from the screen_firmwares directory (unsure which one to use?)
2. Copy the *.tft file to the sd card.
3. Turn the printer off.
4. Insert the sd card into the screens sd slot. It is located on the backside of the screen. Its a bit hidden at the first sight. You can see it "from the inside" of your print volume. Make sure there is only the *.tft file on the sd card.
5. Turn the printer on.
6. The screen will tell you that its flashing - wait patiently untill "updated successed" (not a typo) is visible
7. Turn off the printer
8. Remove the sd card
