DEVKIT Touch Screen under QT

I recently updated the DEVKIT 8000 kernel to Linux-2.6.35-rc3-g85fd48a-dirty and U-Boot to 2010.06-00236-g7385c28 using the git repositories and building them using arm-angstrom-linux-gnueabi toolchain.

Than I cross compiled QT embedded 4.7 from git adding -tslib to the configuration and the path for my staging dir QMAKE_INCDIR and QMAKE_LIBDIR in the qmake.conf to get touch screen support.
It all works pretty well but the touch.

ts_calibrate works very well but once I try to use the QT mousecalibration tool I get a very strange behaviour that it seems to lack resolution at all, drawing a small circle results in a square :slight_smile:

I didn’t have these problems using the kernel and u-boot on the CD both with QT 4.6.3 and 4.7 although the touch was not behaving very well for other reasons…

Thanks

I have to correct my previous post,

the problem does not rely on QT anyhow, since ts_test shows the same behaviour, ts_print_raw confirms that the resolution is really poor.
The resolution of the touch screen in 2.6.35 is really poor, while it is fine with the shipped 2.6.28 kernel.
QT works fine, as usual.
I recompiled and recompiled 2.6.35 using the standard devkit8000_defconfig and also applying small changes with no results.
