Problem with calibration of AT91SAM9M10EKES

Problem with calibration of AT91SAM9M10EKES

[Ulf Samuelsson]

Hi,
I have some calibration problem with my private branch
(ulf/linux-2.6.30-2011-01-??) when building the at91sam9m10ekes board.

I am running /usr/bin/run-calibrate.sh,
but regardless of how I click, during calibration,
a tap afterwards always results in detection 3 mm above the tap.

There is a "pointercal" file generated.
It appears to me that this is ignored...
I can tap 1 cm above or below during calibration,
and still the detected tap is 3 mm above the actual tap.

I tried this on two boards, with the same problem!


I looked at 89xTs_Calibrate
There is no /etc/init.d/devmand  - What does this file do?

Anything else to think about?
I enclose  /etc/X11/xorg.conf and /etc/ts.conf.

----------------------------------------------------
xorg.conf:

Section "ServerLayout"
     Identifier "default"
     InputDevice "atmel-tsadcc" "CorePointer"
EndSection

Section "InputDevice"
     Identifier "atmel-tsadcc"
     Driver "evdev"
     Option "Device" "/dev/input/touchscreen0"
EndSection

Section "InputDevice"
     Driver        "mouse"
     Identifier    "Mouse[1]"
     Option        "Buttons"    "10"
     Option        "Device"    "/dev/input/mice"
EndSection

Section    "InputDevice"
     Driver        "kbd"
     Identifier    "Keyboard[0]"
     Option        "Protocol" "Standard"
EndSection


----------------------------------------------------
ts.conf:
# Uncomment if you wish to use the linux input layer event interface

You are using full X11 with evdev driver so tslib is not used at all. You have 
to use xinput-calibrator.

Hmm, I thought I was using xserver-kdrive!

(Have PREFERRED_PROVIDER_xserver = "xserver-kdrive" in the machine conf 
file)

Looking closer at the image (x11-at91sam9-image), it contains
XSERVER = "xserver-xorg \
            xf86-input-evdev \
            xf86-input-tslib \
            xf86-video-fbdev "
so the xserver-kdrive is overridden.

This was copied from "xorg-image.bb" which I guess then have the same 
problem
using full x-server and tslib.
"qt4-x11-base-image.bb" has this combination as well.

"xserver-common_1.33.bb" is built and contains:
+++++++++++++++++++++++++
RDEPENDS_${PN}_append_angstrom = " tslib-calibrate "
RDEPENDS_${PN}_append_shr = " xinput-calibrator "
-----------------------------------------------------
and I am building "angstrom" I do not get "xinput-calibrator"

I added xinput-calibrate to the x11-at91sam9-image, but after the build,
Removed "xf86-input-tslib", but the dependence on "tslib-calibrate"
remains in "xserver-common_1.33.bb"
Maybe this needs to change as well.

I get the  same startup calibration program ("run-calibrate.sh"  calling 
ts_calibrate).
with the same poor result.

There are no scripts calling "xinput-calibrator".
Shouldn't that happen at startup?

Can call it manually, and then suddenly I am much better off.
Still  it not perfect though.

Any clue to get xinput-calibrate to run at first boot?

provide 
recipes/xinput-calibrator/pointercal-xinput
data for your device and use
recipes/xserver-common/files/89xTs_Calibrate.xinput_calibrator.patch
like SHR does

intentionaly it prefers provideded data, because users too often messed
initial calibration on first boot and then didn't know how to reset it
and rerun xinpu-calibration successfully...

OK, then is the question how:
As I noted:
SRC_URI_append_angstrom = " file://xtscal-fix.patch "
RDEPENDS_${PN}_append_angstrom = " tslib-calibrate "
RDEPENDS_${PN}_append_shr = " xinput-calibrator "?

so Angstrom (which I am using) is using "tslib-calibrate"
Is there any drawback in changing this to " xinput-calibrator "

Adding a SRC_URI_append_at91 seems a kludge.
