wm-tools — Flash Utility for WinnerMicro MCUs

A native Rust implementation of a flash utility for WinnerMicro MCUs (W800/W801 family), including the DSO3D12 oscilloscope.

Based on the reference Python tool from the WinnerMicro IoT SDK: https://github.com/winnermicro/wm_iot_sdk/tree/master

• Auto-detects the highest supported baud rate (up to 2 Mbps)
• XMODEM-1K protocol with CRC-16 verification
• Progress bar with ETA during flashing
• Lists available serial ports with USB product info
• Optional flash erase before writing
• DTR/RTS-based automatic device reset

A graphical application that allows you to visualize and save dumps and screenshots from the ZeeWeii DSO3D12 oscilloscope.

Once connected, the application automatically retrieves debug dumps and snapshot view data from the device, provided these features have been activated via the device buttons. These graphs can be saved as PNG files or exported as CSV data.

To use the snapshot view feature, you must install the modified firmware. For more details, visit ZeeTweak. The debug dump export feature is available by default.

• Rust toolchain (stable, 2021 edition or later)
• A USB-to-serial adapter connected to the target device (or integrated one)

cargo build --release

The binaries are produced at:

cargo run --bin dso3d12-gui

./target/release/flash -l

Auto-selects the port and negotiates the highest available baud rate:

./target/release/flash -i dso3d12_v3.0.6_III.fls

Specify the port explicitly:

./target/release/flash -p /dev/tty.usbserial-1110 -i dso3d12_v3.0.6_III.fls

Flash multiple images in one pass:

./target/release/flash -p /dev/tty.usbserial-1110 \
    -i bootloader.fls -i app.fls

./target/release/flash -p /dev/tty.usbserial-1110 -e

./target/release/flash -p /dev/tty.usbserial-1110 -e -i firmware.fls

Supported rates: 2000000, 1000000, 921600, 460800, 115200.

./target/release/flash -p /dev/tty.usbserial-1110 -b 460800 -i firmware.fls

1. Connect the supplied USB cable to your PC while the oscilloscope is powered off.
2. Press and hold the power button. The scope may enter a power-cycling loop — keep the button held down continuously until flashing reaches 100%.
3. The tool resets the device automatically via DTR/RTS. Use -m / --manual-reset to suppress the automatic reboot after flashing.
