Trouble using Wavlink UMD05 Pro Rev. C1

filipleple commented 4 months ago

Component

Dasharo firmware

Device

NovaCustom V56 14th Gen

Dasharo version

v0.9.0-rc2

Dasharo Tools Suite version

No response

Brief summary

There's trouble using an early revision of the station, namely with video output and USB-C power supply detection

How reproducible

The charging problem is a 100%, the video is seemingly random, occurs after a couple of re-plugs or instantly

How to reproduce

Try to plug in the rev. C1 station and see if the platform detects being charged, or gives video output via the station

Expected behavior

It should be getting charged and always giving video output (as long as the monitor is connected, ofc)

Actual behavior

Sometimes, after a couple of plug ins and unplugs, the platform will stop detecting the station as a video output. No amount of USB-C nor HDMI reconnecting helps, the AC needs to be unplugged and plugged back in to the station
I've managed to get the platform to detect the station as a power source only once, first time I've plugged it in

Reminder: A newer revision (E) of the same station model works seamlessly.

Does it also happen on v0.9.0-rc5? I can test on our side :-)

I confirm it still happens on v0.9.0-rc5. I see in PD traces that the laptop eitther:

Does not establish a PD contract at all
Correctly requests 20V, Vbus goes to 20V, but charging does not start - PD controller may be keeping input switches closed I guess

Need to check PD controller configuration again

Apparently the hardware in the dock failed, a capacitor fell off.

@wessel-novacustom So if you could test on rev C on your side that would be great, as we have a failed unit here.

Just tried with dock rev. C1 on the V540TU, Ultra 5, Ubuntu 24.04 LTS and Dasharo v0.9.0-rc7. Charging and video output are always working for me as it should.

Please keep in mind that video output and charging are only expected to work if the dock is connected to the USB-C port at the right side that is the closest to the USB-A port. The other one doesn't support Video Alt Mode, although charging seems to work fine on it.
