Hello,
I have PinePhone (3GB variant) with Pine''s convergence docking bar. It worked fine for a while, though there were some occasional bugs (e.g. usb-c power don't work or docking bar no longer recognized and pinephone reboot is needed for bar to work again). But later eth port, hdmi and usb-c ceased to work at all: the phone is no longer charged via bar's usb-c, eth port is not visible (leds are down, no eth device created) and HDMI output no longer works. Both USB-A ports still work fine (I can connect mouse/keyborad/USB flash to the pinephone) and USB-C seems to provide power to the USB-A devices (e.g. usb mouse diode is turned on when I connect it to the docking bar with power plugged in into usb-c port while disconnected from the pinephone).
First I though this is some software bug, but reverting to older kernel where it worked doesn't help. Then I updated ANX7688 firmware from Megi's tree, but the bug is still here. It is possible that there is physical damage to the docking station, because I carried it often in the backpack, but there is no visible damage on the bar or its cable.
Have anyone encountered similar problem? Maybe this is a known issue I'm struggling about.
Any thoughts?
How convergence docking bar casing can be opened safely? Looks like it has some internal hatches, but I'm not sure. I want to examine internals for some obvious problem like broken circuit soldering.
