OPIE on Innovator 1510

OPIE on Innovator 1510

[James Selvam]

Hi All,

Im trying to use OPIE on my OMAP 1510 Innovator board. I have used the root
file system image available at familiar.handhelds.org (
opie-image-v0.8.4-rc1-h6300.rootfs.tar.bz2).

I have enabled the Touchscreen as an input device and configured the OMAP
Innovator touchscreen. This has indeed been enabled as seen from the
following messages at bootup:

ts: Compaq touchscreen protocol output
input: omap_ts as /class/input/input0
OMAP touchscreen driver initialized

The innovator, however, comes to the startup screen and stops there waiting
to be tapped. It does not take the tapping.

The debug console shows that the udev is unable to create the
/dev/input/input0/event0 device.

There seems to be a missing link between the drivers and the application. If
anybody has faced similar issues plz let me know.

Thanx,
James.

Yes, it seems there is something wrong with udev in recent familiar
images, so we just disable udev when using this image and recreate the
/dev nodes manually in one of the init scripts before X in
/etc/init.d, e.g.
  mkdir -p /dev/input
  mknod /dev/input/event0 c 13 64
  mknod /dev/input/event1 c 13 65
etc, or you can just make sure that nothing overwrites /dev. If you
also experience problems with the calibration, the easiest hack is to
calibrate the touchscreen without OPIE (e.g in GPE) and copy
/etc/pointercal over.

Hi All,

As specified in my earlier mail, I have downloaded an opie built rootfs. But
the OPIE will not go beyond the initial screen. It asks me to tap to start
but does not. Also if I ran the OPIE applications (like calculator or
datebook) from debug console it puts up the appln window but does not take
the input from touch screen.

I then independantly compiled applications like ts_calibrate and ran it. It
runs; and gives the right coordinates; showing that the touchscreen
interface is all right.

Now the only difference I can see is that these applications (ts_calibrate)
were statically built (without dynamical linking) whereas OPIE may not. But
when I am loading the applications (like calculator) certain messages are
thrown out which indicate dynamic linking (the libapplets.so being loaded
etc).

Is there any configuration that I am missing?

Regards,
James.

PS :  The udev indeed has problems due to which certain devices are not
created. All devices have been manually created and the corresponding
/dev/input/input0/event0 is added & working.

The problem is caused because unlike generic omap1510, the h6300 uses
tsc2101 chip for the sound and touschreen.
So if you want to use that image, you need propably build and install a
new omap1510 kernel for that image.

Then you need to make sure that /etc/modules contains the drivers you
need to use.
In addition for this, you need propably change also the tslib
configuration to be generic omap1510 specific.
See /etc/profile.d/tslib.sh...
