Command-line implementation of the WCHISPTool in Rust, by the ch32-rs team.
This tool is a work in progress.
- NOTE: CH32V003 DOES NOT have a USB ISP interface, use WCH-Link to program
- NOTE: This tool is for USB ISP, not using with WCH-Link
- ch32-rs/wlink is a command line tool for WCH-Link
The prebuilt binaries are available on the Nightly release page.
For Windows users, you will need vc runtime to run the binary. You can download it from Microsoft.
Or else, you can install it from source.
# install libusb for your platform
# macOS
> brew install libusb
# Ubuntu
> sudo apt install libusb-1.0-0-dev
# install wchisp
> cargo install wchisp --git https://github.com/ch32-rs/wchisp
# or use
> cargo install wchisp --force
Prebuilt binaries are available on the Github Actions Page. Click the newest runs at Github Actions Page and download the binary from "Artifacts" section.
If you are using Windows, you need to install the WinUSB driver for your device. See Zadig.
NOTE: This is not compatible with the Official WCH driver you installed with IDE.
If you are using Linux, you need to set the udev rules for your device.
# /etc/udev/rules.d/50-wchisp.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="4348", ATTRS{idProduct}=="55e0", MODE="0666"
# or replace MODE="0666" with GROUP="plugdev" or something else
Arch Linux users can install wchisp or wchisp-git via the AUR.

This tool should work on most WCH MCU chips. But I haven't tested it on any other chips.
- CH32V307
- VCT6
- RCT6 #8
- CH32V103
- CH32F103
- CH552
- Works but might be buggy #10 #14
- CH582
- CH58xM-EVT
- CH573
- CH592
- CH579
- BTVER: 02.90 #18
- CH559
- CH559TL_MINIEVT_V20 by wch.cn
- CH32V203
- ... (feel free to open an issue whether it works on your chip or not)
- chip detection, identification
wchisp probe
wchisp info
- flash and verify code
- ELF parsing
- hex, bin, ihex support
- skip erasing, verifying, resetting
- chip config register dump
wchisp config
- works for most chips, but not all. Issues and PRs are welcomed
- write config registers
- reset config registers to default
- write config with friendly register names? like
wchisp config set SRAM_CODE_MODE=1 ...
- EEPROM dump
- EEPROM erase
- EEPROM write
- select from multiple chips(using
-d
to select device index)wchisp -d 0 info
- ISP via UART or Net

This project is under active development. If you have any suggestions or bug reports, please open an issue.
If it works for your devices, please open a pull request to modify this README page.
It it doesn't, please open an issue. Better provide the following information:
- chip type (with variant surfix)
- debug print of usb packets
- correct usb packets to negotiate with the chip (via USBPcap or other tools)
