CH32V307 Evaluation Board RISC-V

(1/1)

badbyte:
Hi people,
I have bought on aliexress an evaluation board for the CH32V307 here.
I have bought 2 of those and one showed up with the following lsusb output:

--- Code: ---Bus 001 Device 012: ID 1a86:8010 QinHeng Electronics WCH-Link
--- End code ---

And the other showed up in lsusb as follows:

--- Code: ---Bus 001 Device 011: ID 4348:55e0 WinChipHead
--- End code ---

The second one doesn't respond to eclipse's queries at all, in the Configuration of the Download Configuration.

From the output of lsusb I conclude that the firmware on the 2nd isn't the proper one.
Can someone pointme to the right direction???

GromBeestje:
This looks to me like one of the boards gets into the debugger firmware, and the other baord is stuck in bootloader mode.
WinChipHead has a Windows-only tool to configure and update their programmers, the dongles and the built-in EVB boards alike.
Try the tool at https://www.wch.cn/downloads/WCH-LinkUtility_ZIP.html and see if it can configure the boards to RISCV debugger mode.
