Need document how to compile a working JTAG debugger

Hi,

First thanks for the great work of SushiBits. I'm just a hobbyist (and a newbie) so don't know much about embedded. Now that there is a new chip GD32VF103 which is RISC-V based, and said to be pin-to-pin compatible with STM32F103, so I am thinking if I can get it working with some arduino compatible board and then learn about it, so I find SushiBits. However I cannot get the DAP42 firmware working.

From the branch name, I think the sb1 branch is for the SushiBits, so I switched to it and installed GNU MCU Eclipse to compile. Given I did not find a .cproject for compiling, I copied it from the master branch. After flashing into STM32F042F6P6, system can detect it in USB

$ lsusb ...... Bus 003 Device 008: ID 0002:d401 Ingram

However, openocd do not work. I am trying against a GD32F103C8 ( the ARM Cortex M3 one, which IIUC is compatible with STM32F103C8)

I tried to flash the origin DAP42 by Devan Lai, it works fine, and I can download program into the GD32F103. So I believe it's not my soldering issue.

So can you point me if it is possible to run DAP42 with JTAG support in STM32F042F6P6? If so, can you point me how can I build the firmware (or can you provide me a working firmware)?

Thanks.
