Includes a "CH2 50% auto-set" fix to correct a slight vertical offset. How to Check Your Version
Trigger hold-off can now be set manually (100ns to 500ms), making it possible to decode complex pulse trains that would confuse the stock auto-trigger.
Official firmware updates are typically distributed via the manufacturer's support site . Manual Update Process Connect the to your PC via USB.
If the oscilloscope boots normally but ignores the update file on the storage drive, the system cannot read the file. dso2512g firmware
This is perhaps the most compelling part of the DSO2512G's firmware ecosystem. A developer, known in the community as (or timschuerewegen on GitHub), has created a series of modified firmware that dramatically expands the oscilloscope's capabilities.
Note down the current firmware version and hardware board number (e.g., V1.x or V2.x).
Ensure the firmware you download is compatible with your PCB version (e.g., v9.15), as flashing the wrong version can cause instability or input failure. SD Card Support: Includes a "CH2 50% auto-set" fix to correct
The firmware on the DSO2512G is the low-level software that manages:
Set the baud rate (typically 115200 or higher for stable transmission).
Even with careful installation, you might encounter some issues. Here are a few common problems and their solutions: Manual Update Process Connect the to your PC via USB
occasionally receives firmware updates to address bugs or add new features, such as improved trigger modes or measurement cursors. Below is a draft of the key information and steps for managing its firmware.
| Problem | Likely Fix | |--------|-------------| | Scope doesn’t detect update file | SD card not FAT32; or file not in root; or file name changed | | Update starts but freezes | Bad SD card – try another one (old 1GB/2GB cards work best) | | After update, buttons don’t work | Perform a factory reset: Menu → System → Reset Defaults | | Scope won’t power on after update | Contact FNIRSI support – you may need to re-flash via USB/ST-Link (requires opening the case) |
Official firmware updates often address core stability, trigger modes (Auto/Normal/Single), and built-in signal generator settings. : A common stable release found on many newer units. V1.2.8C+ : An older stable branch still in wide use.
Ensure the device is recognized. If you see a yellow exclamation mark, you must download and install the CH340 or STM virtual COM port drivers. Step 4: Flash the New Firmware Open your downloaded flashing software. Select the correct COM port assigned to your oscilloscope.
Some newer hardware revisions allow updating via an SD card.
