2008-12-18 05:02:34 BF527 EZKIT with Qt and tslib problem

Nikolay Chokoev (IRELAND)

Message: 66855

Hi,

I've built uClinux (uClinux-dist-2008R1.5-RC3) with tslib and it works fine. At least I can run ts_calibrate and it works fine.

I've built Qt (qt-embedded-free-3.3.5) with tslib support:

./configure -shared -depths 4,16,24,32 -no-cups -no-ipv6 -embedded bfin -little-endian -thread -qt-mouse-tslib -L/home/uclinux/uClinux-dist-2008R1.5-RC3/staging/usr/lib -I/home/uclinux/uClinux-dist-2008R1.5-RC3/staging/usr/include -lts -qvfb

The Qt displays images on screen without any problems. The only problem is that cannot accept any touchscreen events.

environment is:

export QWS_MOUSE_PROTO=Tslib:/dev/input/event0

export TSLIB_TSDEVICE=/dev/input/event0

export TSLIB_CALIBFILE=/etc/pointercl

export TSLIB_CONFFILE=/etc/ts.conf

export TSLIB_CONSOLEDEVICE=none

export TSLIB_FBDEVICE=/dev/fb0

export HOME=/

export SHELL=/bin/sh

export PATH=/bin:/usr/bin:/etc:/sbin:/usr/sbin

export TERM=linux

The target is BF527 EZKIT LITE 1.4

Can anyone suggest me, please, how to debug this.

Regards,

Nikolay

No ideas?

Could it be a network issue? I desabled almost all network options in the kernel configuration. The QWS server uses the network doesn't it? Do I need any specific network option/feature to be enabled?

What about the libraries path? Should I get a message if the Qt application cannot find the tslib library (or it is staticaly linked)?

Is there any debug option in Qt/tslib I can enable and use?

Thanks for the reply, Mike.

I tried this way, also tried with "=Tslib" (don't know if it is case sensitive).

BTW what is the diffefence between "=tslib" and "=tslib:/dev/input/event0"?

Is there a way to debug tslib <-> Qt interface?

I really have no idea whats wrong. What I'm missing?

Hi Mike,

The event_test works fine. Also all ts_xxx test applications also worked fine. This makes me thinking that the tslib works on that target.

In other hand the Qt application draws the image on the screen.

The only problem is that the Qt application doesn't accept the touchscreen events (or at least it seems like that).

Mike, is there a patch for the Qt 4.4.3 ?

Hi Mike,

I'm downloading svn/trunk now.

Can you give me, please, some instructions how to build the qt4.4.3 and the ucLinux with qt support?

Do I need to copy the qt sources to the uClinux tree, downloaded from svn/trunc?

How can I build only the qt4.4.3 library and use it with uClinux-2008R1.5-RC3 sources?

Sorry for the stuppid questions, but I'm new to linux.

Thanks Mike,

now I can build everything successfully!

I'm trying to use MAX1233 driver in the 2.6.28-rc2-ADI-2009R1-pre, but facing a problem. I'm using the same source as in 2008R1.5, where this driver works.

The error is:

max1233_probe: tries probe...

spi0.2:esFailed to probe MAX1233 Touchscreen, (0 != 0xF00F)

What is changed between these releases? How to solve this?

I had this error again, but at work, with 2009-pre release. It appears when I run 'make' twice, without 'make clean' between. I don't know if 'make clean' helps, as the build process is a little bit slower. I'll have more info tomorrow.

Hi Mike,

Finaly I finished with the build process. The MAX1233 mount problem was because of missing to 'patch' th spi_bfin5xx.c file. The Qt now work with the touchscreen on BF527 board just fine.

Thanks a lot for your help! You have a beer from me ;).

No, it is not missing patch. I missed to change ( to 'patch') the 'spi_bfin5xx.c' file to allow it to work with the max1233 driver. It is not an official patch, just comes with the max1233 driver I found.

since you ran `make` already, you've generated wrong local files. you need to clean that up first by using _clean rather than _only.
