Hello,
there is a little group of peoples running the Tegav2 images of
AndroidX86 on their WeTabs and ExoPCs. They have made some changes
to the Tegav2 image to get more compatible to that tablet PC. I give
you my experiences with it and the links to the modifications.
The target of this email is to sensiblize you on the needs of the
users of WeTab/ExoPC and other Pegatron Lucid based Atom Tablet PCs,
so that in the future the Tegav2 images could also run on these
without any changes.
Mostly these peoples at the
wetab-community.com forum are using a
modified 3.2.2 image based on the Tegav2 image on
androidx86.org.
They also tryed the 4.0x version but found that it is still too
unstable to use it, most testers report that at least 10 minutes it
hangs up. The 3.2.2 image is much more stable, I could use it more
than 3 hours per session before it hangs up.
First I report you the modifications which have been done to the
Android X86 3.2 Tegav2 image to support the Pegatron Lucid platform:
1. Currently the mod is based on:
http://android-x86.googlecode.com/files/android-x86-3.2-RC2-tegav2.iso
2. Changes:
2a: WLAN sometimes does not get a DHCP adress after connect, this
solves it:
chmod 777 /system/etc/dhcpd/*
2b: The touchscreen is detected as a mouse, the
follwoing changes this:
cd /system/usr/idc
cp Vendor_03eb_Product_201c.idc Vendor_0eef_Product_72a1.idc
2c: The screen light can only be adjusted after after replacing a
file:
cd /system/lib/hw
rm lights.tegav2.so
wget http://www.steckbecken.at/wp-content/uploads/lights.tegav2.so
Note that this change is not compatible to the
original Tegav2 platform, so maybe there must be some
modifications to this file to be able to support both Tegav2 and
Lucid with one file. Would this be possible?
2d: To be able to use a real SD card beside a
fake-SD:
cd /system/etc
mv vold.fstab
vold.fstab.bak
2e: To make GPS useable on the Lucid platfrom with the
GPS/3G-module:
cd /system/lib/hw
rm gps.tegav2.so
wget http://www.steckbecken.at/wp-content/uploads/gps.tegav2.so
Alos this one should not be compatible to the original Tegav2
platform, so maybe a solution could be found to support both with
one file?
2f: The webcam can be made useable when replacing two other files:
cd /system/lib
rm libcamera.so
rm libcameraservice.so
wget http://www.steckbecken.at/wp-content/uploads/libcamera.so
wget http://www.steckbecken.at/wp-content/uploads/libcameraservice.so
Also these files should not be compatible to the original Tegav2
platform anymore. Maybe it is possible to change also this in a
way that it can suppot both plattforms, Lucid and Tegav2?
2g: The following mod makes the following functions functional,
but it still has two negative issues. The negative issues are that
the screen light gets a bit darker and on some users WeTab it
influences the CPU fan negative, it might not run anymore what is
fatal as the tablet is no more cooled. They currently think that
this mod is checking the hardware management controller too often,
so that it might get overloaded and hangs up. On my own WeTab the
fan control still works with this change.
The following files are required, as for the issues in the forum
they are marked as experimental:
-
http://www.wetab-community.com/index.php?app=core&module=attach§ion=attach&attach_id=6072
( asus-laptop.ko.gz )
-
http://www.wetab-community.com/index.php?app=core&module=attach§ion=attach&attach_id=6073
( sensors.tegav2.so.gz )
Then run these commands:
cp asus-laptop.ko /system/lib/module
s/3.0.1-android-x86-tegav2+/kernel/drivers/platform/x86
cp
sensors.tegav2.so /system/lib/hw
boot with DEBUG=1
exit
depmod -a
exit
2f: The internal 3G modem still does not work well, it is detected,
but it seems to hang up after detecting the available networks. The
problem has not been solved yet. Further details can be found here:
http://www.wetab-community.com/index.php?/topic/17917-android-322-komplett-rc2-image/page__st__320__p__247284#entry247284
and following messages (in german).
From Windows Devicemanager, Huawei Mobile Connect 3G Modem:
- USB/VID_12D1&PID_1404&REV_0000&MI_00
2g: For the Atheros Bluetooth module no driver yet.
From Windows Devicemanager:
- USB\VID_13D3&PID_3304&REV_0001
2h: This summary is based on the following german threads in the
WeTab community forum:
I.

(list of changes)
II.

(322 rc2 image discussion)
3. A fully modified image runable on the Lucid/WeTab/ExoPC/... can
be downloaded from message No. 1 of this thread, it is always
updated with the newest changes:
http://www.wetab-community.com/index.php?/topic/17917-android-322-komplett-rc2-image/
The instruction of this messaqe in the forum shows how to boot this
image out of a Windows 7 / 8 partition using NeoGrub and BCDEdit.
This is very interesting for those who own an ExoPC which comes by
default with Windows 7. Or for those who have deleted WeTabOS and
replaced by Win 7.
I hope that one of the Android X86 group will have a close look in
this message and helps to improve the developement of Android X86 to
support more platforms. If you have any questions or you need help,
just contact me or the user Halver of the wetab-community forum as
the responsible for the most of the changes at the 3.2.RC2 image.
Thank you all,
Stefan
