Updating the firmware
From Sonic Potions Wiki
Start firmware update
- Get the latest firmware version: http://forum.sonic-potions.com/discussion/29/latest-firmware-version#Item_20
- Make sure your SD card is using FAT32! Otherwise you will get a “Firmware error” message,
as the bootloader can only read FAT32 filesystems.
- Copy the 'FIRMWARE.BIN' file to the SD cards root directory.
- Insert the card into the turned off LXR.
- Push and hold the encoder, then turn on the synthesizer.
