Need help installing androidx86 4.4 on IBM thinkpad x41

[Travis Allen]

Ok so I've followed the tutorial on the main site about 20 times and to no avail

I installed 4.4 rc1 first following the directions from the tutorial and everything installs fine then when it goes to boot I get A n d r o i d root@x86:/ #

and it just sticks there.

I managed to download and get the 4.0.3 thinkpad version installed and worked fine on the first try other than the fact I could not use the pen which comes with it.

Tried installing the 4.4 again changing the android_x86 to thinkpad but still same thing as before. Cannot seem to figure it out, is there something I'm supposed to be inputting to force it along? I've been at a loss and cannot seem to find much information regarding the thinkpad since the 4.0.3 version that was designed for it. 

Any help with this would be greatly appreciated.

Also on a side note, I am not dual booting or using windows. my goal for this thinkpad is to primarily use the android os for drawing since windows makes it massively slow and its old but works perfect as a visual drawing pad. If anyone knows of a better way to accomplish my goal i'd be willing to hear it.

Thanks.

Please get some log of 4.4-RC1 for analyzing.

Enter the debug mode and copy file file
/data/log.txt.

Instead of creating a new topic, I'll post my error log on a X41T ThinkPad IBM using the Build 20140522 from http://forum.thinkpads.com/viewtopic.php?f=9&t=114277

Here it is, in debug mode, the /data/log.txt file

https://github.com/ilakast/errors/blob/master/Android-x86%20KitKat%20build%20for%20Thinkpads%20(tested%20on%20an%20X41T)

Booting stops to the Android prompt and drops to the console, never bringing up the GUI Android.

Here's /data/log.txt from my X41 tablet running the official 4.4-RC2 iso.

After getting to the text "A n d r o i d" screen, the graphical Android logo never come up. The logs show SurfaceFlinger and other stuff running and dying repeatedly, but I can't make out the culprit.

The X41 tablet has Intel 915gm chipset and integrated graphics.

Forgot to actually attach the log. Here it is.

The log said illegal instruction (SIGILL),
seems to mean your cpu is not supported.

The X41t has Pentium M, so it's perhaps an SSE3/PAE thing.
The kernel does not have CONFIG_HIGHMEM64G so it doesn't require PAE (also it boots fine on X41t). Is there any code specific for SSE3, in surfaceflinger and elsewhere, or is it just compiler optimizations?

[twisteroid ambassador]

I've managed to build an image that works on Pentium M and other non-SSE3 CPUs.

The patches are attached for anyone interested, but I don't think they should be integrated into the source tree. There's this lovely snippet about not having SSE3:


ERROR: Your x86 platform image is not compatible with the NDK x86 ABI
As such, you should *not* define TARGET_CPU_ABI to 'x86' in your BoardConfig.mk
to ensure that your device will not be mistakenly listed as compatible by
the Android Market. Also, it is likely that the image will fail the CTS tests
Please undefine TARGET_CPU_ABI in your BoardConfig.mk, or select the value 'none'
The corresponding image will still be able to run Dalvik-based Android applications
Aborting build! Please fix your BoardConfig.mk


Head over to my site for an iso image and more details. https://sites.google.com/site/twisteroidambassador/android-x86/kitkat-non-sse3-build
