DAPLink (CMSIS-DAP) porting to Artery AT32F425, WCH CH32V203 and WCH CH32V305.

DAPLink-AT32F425

DAPLink (CMSIS-DAP) based on Artery AT32F425 (support crystal-less USB), supports SWD, JTAG and CDC.

On C/C++ page of Keil Option Window:

  • Define DAP_FW_V1: generate CMSIS-DAP V1 firmware, using HID transport protocol.
  • Do not define DAP_FW_V1: generate CMSIS-DAP V2 firmware, using WINUSB transfer protocol.

DAPLink-CH32V203

DAPLink (CMSIS-DAP) based on WCH CH32V203 (support crystal-less USB), supports SWD, JTAG and CDC.

On Properties for DAPLink -> C/C++ Build -> Settings -> C Compiler -> Preprocessor page:

  • Define DAP_FW_V1: generate CMSIS-DAP V1 firmware, using HID transport protocol.
  • Do not define DAP_FW_V1: generate CMSIS-DAP V2 firmware, using WINUSB transfer protocol.

DAPLink-CH32V305

DAPLink (CMSIS-DAP) based on WCH CH32V305 (High Speed USB with on-chip PHY), supports SWD, JTAG and CDC.

On Properties for DAPLink -> C/C++ Build -> Settings -> C Compiler -> Preprocessor page:

  • Define DAP_FW_V1: generate CMSIS-DAP V1 firmware, using HID transport protocol.
  • Do not define DAP_FW_V1: generate CMSIS-DAP V2 firmware, using WINUSB transfer protocol.
