Firmware Architecture and Reverse Engineering of the FNIRSI DSO-TC2 Portable Oscilloscope

Abstract — The FNIRSI DSO-TC2 is a low-cost, dual-channel digital storage oscilloscope combined with a semiconductor component tester. While the hardware specifications are well-documented by the manufacturer, the embedded firmware—responsible for signal processing, UI rendering, measurement algorithms, and component characterization—remains proprietary. This paper analyzes the firmware structure, boot process, and update mechanism of the DSO-TC2. Through static binary analysis and hardware debugging interfaces, we identify key software modules, memory mappings, and potential security limitations. The findings provide a reference for hobbyist modifications, bug fixes, and feature enhancements, while discussing legal and technical challenges of reverse engineering consumer test equipment. fnirsi dsotc2 firmware

Part 1: Understanding the FNIRSI DSOTC2 Firmware Ecosystem

Unlike Arduinos or Raspberry Pi Picos, the DSOTC2 is a closed-source device. FNIRSI does not release its source code to the public. However, the company regularly releases binary firmware files (usually .upd or .bin format) to address bugs and add features. Which of these would you like

Phase 2: Flashing the Firmware

  1. Launch the FNIRSI_DSO_TC2_Updater.exe as Administrator.
  2. Select the correct COM port or DFU device (the tool usually auto-detects).
  3. Click "Load File" and select the .bin file you extracted.
  4. Double-check the "Hardware Revision" match on screen.
  5. Click "Update" or "Flash" .
  6. Do not disconnect or power off during the process (usually 30–60 seconds).
  7. A green "Success" message will appear.

5.2 Security & Modifiability

  • No firmware signature check – any modified binary can be flashed.
  • Calibration data is not ECC-protected; corruption leads to bricked device (though recoverable via SWD reflash).
  • Bootloader does not verify application CRC, allowing custom firmware installation without hardware modification.

Device variants and hardware context

  • Models: The DSOTC2 name is used across several similar handheld DSO/DFM devices. Variants differ by LCD size, ADC front-end, microcontroller/SoC, battery, and included probes. Some resellers relabel identical hardware.
  • Typical hardware components:
    • ADC (often a small SAR ADC or dedicated front-end)
    • MCU/System-on-Chip (commonly ARM Cortex-M series or low-power SoC)
    • TFT/LCD display with SPI or RGB interface
    • Buttons/rotary encoder, battery and charger IC, USB-to-serial bridge
  • Implication: firmware is specific to the exact hardware revision; using a firmware compiled for a different revision can brick or impair the device.
