Has this been resolved?

I have to double-check with @Fishwaldo - but my understanding is that you can fix/resume normal charging with adjusting some sysfs file; although I am not sure when is fix for that problem going to be officially added to the PineTab-V distro.

@mbohun Thank you for responding. I see.

By the way, could you refer me to how to set up wifi correctly? I recently got PineTab-V with KDE Plasma installed, but while it sees all wifi networks, I cannot make it connect. I also have no idea how to use a LAN connected (I have a USB-C dock with LAN port).

(Sorry for silly questions, I never used Linux in any form. But I want to make this usable to test MacPorts on it.)

@barracuda156 No problem, those are not silly questions.

• WiFi: in my case I just installed the latest PinIx from https://pine64.my-ho.st:8443/pinetabv-image-plasma-pinetabv-2.1.wic.bz2 and i connected to my WiFi router at home, basically just entered the WiFi password - and i was connected.
• USB-C docks: IMPORTANT that you plug the USB-C docks into the top USB-C port, the bottom USB-C port on PineTab-V is at the moment only for charging. I usually plug the USB-C dock into PineTab-V BEFORE I boot the tablet, I think I noticed some occasional problem when connecting/disconnecting the dock while the PineTab-V was running.
  • PinePhonePro_dock: I just plugged the PinePhonePro_dock in and it works fine (ethernet, USB ports)
  • KOGAN USB-C dock: i just plugged this one in at it worked fine (ethernet, USB, SD card readers); check the link for chipset info

@mbohun Thank you!

I need to check which version is installed (I purchased it with OS installed already). Do I just clone the extracted image onto the SD card (perhaps dd can be used)? If it is not too complex, I rather re-install the OS afresh even if the version is the latest at the moment.

Yes, normally I just put the new image onto a SD card (with dd) then I boot from the SD card, and then I copy or download that new image again while I am running from the SD card, and dd that image on the eMMC, then I reboot, pull out the SD card, so PineTab-V boots from the eMMC.
Obviously backup your files and data first, before doing a reinstall.

The charging issue is hardware related. The fix is coming in the next revision of the hardware. The /sysfs/ trick just tricks the hardware into high current mode. There is no “fix” in software for the issue.
