Android-x86-8.1-rc2 Dell Venue 8 Pro 5830 Issues

[UniCav]

I have a perfect install up and running on my Dell Venue 8 Pro 5830. Overall seems responsive and functional.

Chrome, Google Play, Youtube working fine.

Sound seems fine

Wifi is workiing, but indicator shows no signal and details show Poor Signal even though it's getting perfect signal

Battery indicator always shows Charging, details always say 100% up to the point the battery dies and the tablet goes dead.

Screen does not actually go off in sleep mode, just blanks out. Occasionally pops back on by itself. kills the battery.

Are Atheros ath6kl, and the other libraries and firmware for the Dell Venue in this release?

I'm not up to speed on deconstructing Android so It'll take me a while to sort out. 

On Linux it was the firmware and drivers in this repo https://github.com/AdamWill/baytrail-m/tree/master/baytrail-firmware

Can't seem to enable MTP mode on the developer options so I can't get it connected to my computer to do more in depth work,

Changing the USB Mode from Charging to MTP crashes settings and doesn't stick.

mtp mode request device has otg chip，what is otg chip，

dual os tablet onda/teclast/chuwi，has TUSB1210 chip.

CPU is

dmesg is nothing but this error repeated. I believe this even comes up during boot

This is what the actual hardware should be, but I still see nothing about OTG

The only reason I was looking for MTP/OTG was to be able to access the device from adb terminal to make it easier to debug what's missing on the unit

At some point during testing distro boots I had disabled xHCI in the BIOS.

Reenabled that now but it still will not allow me to select MTP in the Developer Options.

Settings App crashes and Select USB Configuration returns to Charging.

I'm also finding now that after I leave the tablet on and plugged up all night to charge the battery that when I come in the next day, as reported earlier the screen is not off it's simply blanked, and even though it will show the lock screen when I push the power button it will not recognize a swipe on the screen. I have to force power off and back on.

Just use adb over tcp/ip:

adb connect ip_of_android_x86

(do it on your debug host)

[UniCav]

Since the wifi is completely disabled because of the missing firmware or kernel modules this will not work.

My goal was not to need MTP or ADB. I was only trying to get into the system to help troubleshoot this and get it working.

[UniCav]

PCI Mode is not available in this version of the Dell Venue 8 Pro 5830 BIOS.

The only options available are xHCI Mode Enable/Disabe (I've already tried both), Enable UEFI Network Stack (for PXE), Enable USB Boot (enabled), External USB Ports (Enabled),

So none of this changes the functionality.

When this device is running any Windows version the MTP protocol does work. OTG Cables do work as well.

[UniCav]

I have never attempted compiling an Android kernel. It's been a very long time since I compiled kernels for Linux.

I do know the device is capable of supporting OTG.

I will look into this further and let you know if I have any success.

I do appreciate your responses, this device is very fringe now so not popular to support.

[youling 257]

When this device is running any Windows version the MTP protocol does work. OTG Cables do work as well. 

what are you want doing? under Windows, you can use otg cables connect usb keyboard/mouse, your tablet under windows is a host machine,

your Android phone can micro usb cable connect your tablet otg cable, your Android phone is a client machine.

under Linux/Android, with pci xhci, the tablet always is host machine, of course can use otg cable connect usb keyboard/mouse.

what i said "bios otg pci", the mean is the tablet can be a client machine, tablet micro usb cable connect computer, computer is host machine.

your tablet running Windows mtp protocol work, my understand is your tablet(Windows) micro usb cable connect other one computer(windows), can transfer file?

1st - Correction - I apologize, I have been testing several OS builds on this tablet and I have confused issues from another OS with this thread

Wifi does work, so ADB over TCP/IP might be possible

I am trying to find a usable replacement for Windows on this tablet. I do not want dual boot and do not want Windows on it.

But with this release of Android-x86 there are still too many issues for it to be usable.

I was trying to troubleshoot these issues per everyone's replies, but it's too hard to do on the tablet screen and on-screen keyboard

Then I discovered the USB port is not working while booted into Android, so ADB and external keyboard won't work.

I will look through these suggestions more when I go back to testing again

[youling 257]

did you test 4.9 kernel 8.1 rc1? 4.15 kernel Ubuntu 18.04? 4.18 kernel Ubuntu 18.10 ?

if 4.9 and 4.15 kernel usb work, the 4.18 kernel usb port problem make be because "gpiolib-acpi: make sure we trigger edge events at least once on boot"

Hello UniCav,

can you compile the android-x86 code yourself?

If you can, you may want to try reverting the commit, that I mentioned here: https://groups.google.com/forum/#!topic/android-x86/jTkVo4lo-S4

I also have an Atom based device with the same battery indicator issue. Reverting that commit and compiling the code myself, I fixed the issue. Maybe you confirm that solution.

[UniCav]

I'm actually setting up my environment to build now and will attempt this soon. Thanks

[UniCav]

Getting ready to config and compile, wanted to see if this patch looks right to you?

Looks good. Give it a try.

[UniCav]

I have a working build. Wifi indicator and Battery Indicator are working properly.

Sleep is not working properly. Pressing power/sleep button will put unit to sleep, but screen backlight comes back on and runs down battery.

Tablet will not wake from sleep with any button, has to be force powered down and rebooted.

Suggestions?

[youling 257]

so otg cable also worked for you? connect USB keyboard worked for you?

I haven't gotten to the point of verifying OTG yet but I can confirm that USB keyboard and mouse do work.

I've been out a few days but I am preparing a fresh build environment on Ubuntu 18.04 now to see if the latest patch for the LC=ALL issue works.

[youling 257]

your tablet only one micro USB port, USB keyboard plug in otg cable, otg cable plug in tablet micro USB port, USB keyboard work ?

[Cavin Greer]

Yes that is correct. Apologies I did not consider that is an OTG cable to the hub. I was thinking OTG cable to PC for adb programming and USB MTP mode which I am planning to test soon.

OTG cable to hub + USB keyboard + USB mouse + USB flash drive confirmed working

this is two things.

otg cable and USB keyboard plug in tablet, can work.

tablet use micro USB cable plug in PC computer, won't work, your tablet not support.

from begin, i said otg and gadget, it is tablet connect PC computer.

With my new build and install, OTG/USB Hotplug does not work. Not a huge deal, but if I boot the tablet with the OTG connected it's active. connected USB Keyboard and mouse work. Completely disables touchscreen. When unplugged the touchscreen remains disabled and external will not respond either if plugged back in. If already powered on, USB will not activate. After forced off by button and reboot without USB connected touchscreen returned. I had to use USB to install OpenGApps and Chrome Beta but now that I have them I believe it will be usable without needing the external. Would be nice to be able to fix hotplug so it will be available if needed without reboot.
