Touchscreen does't work in rootfs build with buildroot

Ann R.
Hi! I compiled mini6410  rootfs with buildroot, including ts.lib and QT.
But when i touch the screen when ts_calibrate application is launched  -
nothing happens.

I also exported this vars

export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/lib/ts
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_CONSOLEDEVICE=none
export QWS_MOUSE_PROTO=tslib:/dev/input/event0

Can anybody help me in getting over this problem?

davef
cat /dev/input/event0

touch the screen and see if you get any response.

Ann R.
>>cat /dev/input/event0

I see nothing :(

Ann R.
Can the problem be in the fact, that I launch ts_calibrate from terminal,
opened on serial port /dev/ttySAC0? 

Can anybody help Russian girl?

davef
Think you are correct.  I always launch it from the mini2440.  I do know if
you try to launch a Qt app using tslib from the terminal it doesn't work.

Have you got anything on the display on the mini2440?

Try again and report back.

It still doesn't work :(

Have you got anything on the display on the mini2440?

Try looking at all the entries in /sys/devices/virtual/input/input1

event0
event1
. . .

Some tutorials say there should be an entry called:
ts (for touchscreen)

CD your way to <input 1> and either do <ls -la> and you'll see some numbers
like 13:65 etc. OR do <cat dev or mouse or ts >

Note what the numbers are for <ts> and then go back to /dev/input/what
ever_is_in_here and see if you see the same numbers.

If you go to;
http://www.oselas.org/oselas/bsp/pengutronix/mini2440_bsp_en.html
and download OSELAS.BSP-Pengutronix-Mini2440-Quickstart.pdf it describes in
detail in section 4.9.1 some initial checks on the touchscreen.

Ann R., are you using mini2440? I was the same problem, and I discovered
that the Touchscreen driver wasn't selected in the kernel config. Assuming
that you're using buildroot, type:

make linux-menuconfig

Then select the following option:

Device Drivers
  Input device support
    [*] Touchscreens
          <*> Samsung S3C2410 touchscreen input driver

After that, save the config, and then 'make' again.

Note: every time that you run 'make clean', you need to reconfigure this
option.

Ann R., may you give your buildroot config to me?
