Fnirsi Dsotc2 Firmware Jun 2026

Try a different USB port (preferably a USB 2.0 port on the back of your PC). Replace the USB Type-C cable with a known data-sync cable.

As of 2024-2025, FNIRSI has released multiple hardware revisions of the DSO-TC2. Firmware files are not interchangeable between different hardware revisions. Installing the wrong version can permanently brick your device. Always match the firmware to your Hardware Version.

Given the hardware is nearly identical to generic STM32 dev boards, a community effort could port an open-source oscilloscope firmware (e.g., MiniDSO , Scoppy ). However, the component tester requires precise timing and pin control, which is less documented.

By following the steps in this guide—identifying your hardware revision, sourcing clean firmware from official channels, executing a safe flash, and post-calibration—you will unlock the full potential of your device. Keep a bookmark of FNIRSI’s support page, and consider joining the EEVblog forum thread dedicated to the DSO-TC2 for the latest news on beta releases.

FNIRSI typically uses proprietary ISP (In-System Programming) burning tools or standard STM32/FlyMcu software depending on the internal microcontroller chip.

The official firmware burning tools provided by FNIRSI are native to Windows operating systems. Try a different USB port (preferably a USB 2

Once the file transfer is finished, the device screen will display "Update completed" at the bottom.

Firmware updates can expand the device's ability to automatically detect complex components, such as specific types of JFETs or dual diodes.

Extremely important: Only download firmware intended for the DSO-TC2. Using firmware from a different FNIRSI model could cause irreversible damage to your device. Given the hardware is nearly identical to generic

Understanding what changed helps you decide if you need to update.

Before your PC can communicate with the DSO-TC2 in upgrade mode, you must install the required drivers found in the downloaded package. Unzip the downloaded folder.

Finding a reliable guide for the firmware can be tricky because the manufacturer (FNIRSI) does not host a centralized public archive, and because there are "copycat" hardware versions on the market.
