Fnirsi Dso-tc2 Firmware [TRUSTED]

To help find the right version, could you share a bit more about your situation?

A: Yes, using the same SD card method. However, downgrading may corrupt your saved calibration settings. Always do a factory reset after a downgrade.

: Users often look for updates to transition from older versions (like v1.6) to newer iterations for improved stability, though it is generally recommended to only update if you encounter specific faults. How to Update the Firmware fnirsi dso-tc2 firmware

Firmware updates address screen freezes and crash loops when reading high-frequency PWM signals.

What (e.g., Windows 10, Windows 11) is your PC running? To help find the right version, could you

Procedure: Open the case, locate the TX, RX, GND, and 3.3V pads. Connect the serial adapter, open STM32CubeProgrammer, and force the chip into bootloader mode by shorting BOOT0 to 3.3V while resetting. Then flash the original firmware. This is advanced; if you are not confident, send the device back to FNIRSI for repair (they often charge a small service fee).

FNIRSI periodically releases firmware updates to improve measurement accuracy and fix UI bugs. As of early 2024, the most common versions are and V0.3 . Always do a factory reset after a downgrade
