wchisp - WCH ISP Tool in Rust

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
  • Currently I'm working on a WCH-Link implementation

TODOs

• 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(unprotected, debug-enabled state)
  • 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 index) wchisp -d 0 info
• ISP via UART or Net

Usage

> cargo install wchisp --git https://github.com/ch32-rs/wchisp

Tested On

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
  • WeActStudio.WCH-BLE-Core
• CH579

Contribution

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)
