Unsupported wchlink #27

Closed 9names closed 10 months ago

9names commented 10 months ago

Hardware is WCH-LinkE-R0-1v3. Bought from Aliexpress, from WCH Official Store as part of CH32V003/203-LinkE Kit. Tried with stock firmware (2.9), also updated to latest firmware 2.10 with MounRiver Studio.

wlink reports: Error: Unknown WCH-Link variant: 18

command line, for clarity:

$ wlink
Error: Unknown WCH-Link variant: 18

Tested using Ubuntu 23.04

Output from probe-rs wlink fork I added an extra print line for more version info:

I downgraded the firmware to 2.7 from https://github.com/NgoHungCuong/WCH-LinkE-Updater/tree/main/Firmware Now it's not throwing errors any more:

$ wlink
00:13:24 [INFO] WCH-Link v2.7 (WCH-LinkE-CH32V305)
No command given, use --help for help.

So I guess it's just incompatible with firmware versions >= 2.8?

andelf commented 10 months ago

I'm working on a refactor. I'll update the supported firmware version to v30 soon(actually it's a 2.10 or 0x020a, WCH calculates it as buf[0] * 10 + buf[1]).

andelf commented 10 months ago

I'm planning only to support the newest probe in the future. The firmware is forced to be updated to the most recent by WCH's toolchain.

For a debug or tracing session, use wlink -vv.

andelf commented 10 months ago

@9names Could you help test the new version?(not released yet, avaliable via the main branch)

9names commented 10 months ago

Will do. Thanks!
