Any comments?
What we are doing wrong?

IMHO,
gl libraries (such as libGLES_CM.so) seems to have been compiled with EABI v5.
but I think they should be compiled with EABI v4 .

How you identify EABI version of libraries?
IMHO
Problem is in memory allocation fail which is cause incompatible pointer type in kernel modules. (see modules compile output i posted here)

I apologize if I've missed this, it's quite a long thread, but could anyone explain the contents and the structure of the SDK itself? We all jumped right in and tried to make the driver working, but what is the rest of the stuff in there? I understand that they have not released the source code, and because of that, I'm afraid we will not be able to determine what type of EABI is exactly used (if that matters at all), without TI intervening on this matter.

Let's see...

Flash the provided zImage, install the provided libraries and kernel modules, then plug your USB cable, and reboot the N810 (with the USB cable plugged in during the entire process!).

(This will cause your SD cards to not be mounted).

Then, load the mbxaccess.ko module, load the omaplcd.ko module, create the required device nodes, start mbxdaemon, and try the xegltest*. Ensure the screen doesn't turn off.

By now, you should have a big black window. Tap on the applications menu, then tap outside it (to dismiss it). Enjoy.... or not.

Edit1: I know this is all sounds pretty random, but bear with me for a moment

* Edit2: everything as root.

And what would be the point of not mounting the SD card?!

pure magic indeed :-)

I guess physical memory is not fragmented so allocation does not fail.

I am suspecting metalayer-crawler will not index your cards while thrashing your memory in the process.

This trick worked for me. Both with my kernel and the one included.

glinfo and services_test work and do something, xegltest cannot find libXau.so (even if it IS in /usr/lib!)

Without this hack I got same allocation failure everytime and in addition when trying to connect to wi-fi whole device reboots (dma allocation failure in wi-fi driver?). With cards unmounted it works few times and even wi-fi sometimes works and reboots later :-)

I guess it is time to dig out my old N800 with soldered serial cable and strip down boot sequence a bit.

Right. So if you want to have 3d, please remove your SD card(s).

The thing is, I don't even get to the point where the allocation fails. Could be something I've done with the device (though haven't hacked the kernel or anything like that). Maybe I'll reflash the entire device, if I feel up to it.
