Fast firmware update
Updating Core:
- Download the .bin firmware file from the version list below
- Copy the file core.bin to the root of a USB flash drive formatted in FAT32 (do not place it inside a folder and do not rename it).
- Power off Core, then plug the USB flash drive into the USB HOST port
- Hold the encoder button down and power Core on: the screen shows WAITING FOR USB FLASH DRIVE
- Release the encoder. Flashing starts automatically and takes about 10 seconds
- When UPDATE DONE is displayed, Core reboots on the new firmware by itself
- Unplug the USB flash drive
Recommendations:
- The file must be named exactly core.bin and sit at the root of the drive, not inside a folder
- The USB flash drive must be formatted in FAT32 (exFAT is not supported)
- Do not disconnect power or the USB flash drive during the update process
