Fnirsi-1014d Firmware Update Jun 2026

For developers or advanced users, there is an alternative way to load firmware directly into the oscilloscope‘s DRAM using the of the Allwinner F1C100s SoC. This method bypasses the normal USB‑drive procedure and is useful when the normal bootloader is corrupted or when you want to test a new build without writing it to flash memory permanently. It requires a Linux machine and the sunxi-fel tool.

This indicates a corrupted flash or the wrong firmware version. Turn off the device, reconnect it to your PC, delete the corrupted file, copy a known stable firmware version to the root directory, and reboot.

Ensure you are using a USB data cable, not a power-only charging cable. Try plugging the cable directly into the motherboard ports on the back of your PC rather than a USB hub. The Screen Remains Black After Updating (Bricked Device)

Beyond the official firmware, a vibrant reverse‑engineering community has produced , a bootloader with a startup menu , and various enhancements. The main repository is maintained by pecostm32 on GitHub: fnirsi-1014d firmware update

Leo reached for a USB cable—the unusual "A" to "A" type required for this specific device. He clicked the oscilloscope's power button and navigated through the digital menu: > USB export .

Once the scope restarts, verify that the issues you had (e.g., reversed coupling indicator) are gone. If the screen is shifted (a known problem with some early updates), repeat the procedure using the alternative firmware version (e.g., Version B instead of Version A).

At its core, firmware provides the fundamental instructions for how a device interacts with its hardware and external inputs. For an oscilloscope like the 1014D, firmware updates serve three primary roles: fixing inherent software bugs, improving performance (such as waveform stability or calibration accuracy), and expanding compatibility. Without these updates, users often face persistent issues like voltage readout inaccuracies or screen distortion. Manufacturer Updates and the Hardware Fragment

FNIRSI updates its software periodically to patch community-reported bugs.
