Technical Report – Kodak REELS Film Digitizer

Device - Model: Kodak REELS Film Digitizer - Main board:
DV280N_MAIN_V0.6 (2021-04-16) - Processor: Novatek NT96658MBG-NH - SPI
Flash: Macronix MX25L3233F - Motor driver: Trinamic TMC2226-SA - Camera
board: DV280M_S_A4010_V0.1 (2025-03-07)

Problem

After installing the recommended Firmware B, the flashing process
appeared to complete successfully.

Since then: - the scanner either freezes on the Kodak logo or fails to
boot; - once it reached the menu after removing the SD card; - the LCD
works; - the power button works; - all other buttons are unresponsive; -
the motors no longer operate; - scanning is impossible.

All three Firmware B variants produced the same result.

Investigation

The unit was fully disassembled and detailed PCB photographs are
attached.

Main identified components: - Novatek NT96658MBG-NH - Macronix
MX25L3233F SPI Flash - Trinamic TMC2226-SA motor driver - UART header
labeled: 3.3V / TX / RX / GND

The current behavior strongly suggests that the firmware is not
compatible with this hardware revision.

Request

Could you please provide: - the original firmware matching this exact
hardware revision; - or a complete SPI flash dump from an identical
unit; - or the official recovery procedure.

Thank you very much for your assistance.
