Ok, here is an old Freerunner video for comparison (thanks to Raanan Elefant):

https://www.youtube.com/results?search_query=jaRtQOPMBO4

I think we either have lower accelerometer sensitivity or the frame-rate is 
lower.

For the latter we need some expert who knows how Qt really works and
controls the frame rate...

Bugs are like onions or matryoshka dolls :)

Isn't that what one would expect? It starts slowly and becomes faster and 
faster, i.e. accelerates over time.

Or do you mean that the ball is jumping by single pixels if you tilt the device 
just a little?
I have made a short video how it looks on my GTA04:

Does it look the same for you?

Re: [Gta04-owner] Second trial with QtMoko2

2018-04-13 Thread Sven Dyroff

Hello Nikolaus,

on my GTA04A5 it behaves exactly as expected: The ball now moves to the 
correct directions, but slowly and stuttering. Like if you view a film 
with not enough pictures per second.

Best regards

Well, I don't know what you expect for "smooth, fast and natura"l, I just

I have done this test for you: 

GTA04A4 and GTA04A5 with display upside on the table with the same µSD 
card (i.e. boot A5 first, then swap card and boot A4). 
Run evtest /dev/input/accel | head -20 and write down highest X/Y/Z 
values. 

On a GTA04A5:

root@letux:~#  

This means: X=-15/256 = +6%, Y=--5/256 = -2%, Z=274/256 = +107% 

Comparing A4 and A5: they basically behave *the same* regarding the range 
and report both +/-256 for 1g. They just differ in the orientation of the 
sensor. 

I.e. the Z axis also has a sign error. This is still missing in my 
correction patch. 
To make it really precise I should rotate both devices by 90° and write 
down all 
values... 

What I don't know and can't compare is if they behave like a GTA02... And 
if a total value of ~1g is what QtMaze expects. And if the QtMaze makes 
use 
of the Z-axis at all (doesn't look as if it does).

OK thanks I'll look.

I installed amr-gcc/g++-4.7 from apt and it was working fine. I cannot
find place where it's hardcoded to 4.7 though (to have possibility to
change to something newer).

what I had tried is:

http://git.goldelico.com/?p=gta04-qtmoko.git;a=blob;f=README;h=539a8c41dddc9f726641e1d1228d6a548a6a3f53;hb=e8a920c0c4eaef02a060af138f6bec80054bb517#l76

i.e. without chroot. It looks really straightforward and to be the right thing.

But I failed in finding the correct cross-compiler binary for wheezy.
This is when I decided to move to the native build because there is a wheezy 
compatible (non-cross-)gcc.

So which cross-compiler do you use to compile qtopia?

[Gta04-owner] qtmoko2 crosscompilation

2018-04-13 Thread Belisko Marek

Hi,

I tried to find some valuable info about qtmoko2 crosscompilation on
PC (not native on arm board). in README it's written it's not
supported but there are anyway some steps how to do that. I was able
to cross-compile qtopia on my ubuntu 16.04 pc but it fails when
compile qtmoko. Kust want to ask if anybody here have some ideas or
tried to do the same and can share some knowledge. Thanks a lot.

BR,
