[oselas] Mini6410 1-wire touchscreen problem

[david]

Thanks for updating the git version of the mini6410 BSP, everything appears
to be working with the exception of the 1-wire touchscreen. I boot using
the "mini6410=1i" boot argument, and the kernel does print the following
lines:

tiny6410-1wire tiny6410-1wire: Tiny6410 1-wire host initialized.
input: Tiny6410 Touchscreen as
/devices/platform/tiny6410-1wire/tiny6410-1wire-touchscreen/input/input0

 I edited the /etc/profile.environment file to add the tslib variables:

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

Then I edited the /etc/ts.conf file to change to the 1-wire tslib driver:

module_raw one-wire-ts-input
module pthres pmin=1
#module variance delta=30
module dejitter delta=10
#module group radius=10 nbpoints=16 threshold=12
#module skip nhead=4 ntail=4
#module lowpass factor=1 threshold=1
#module median depth=2
module linear

Running ts_calibrate gives the following output, but never waits for me to
touch the screen:

root@mini6410:~ ts_calibrate

Running "evtest /dev/input/event0" gave the following output, but didn't
print anything when the screen was tapped:
Input driver version is 1.0.1
Input device ID: bus 0x0 vendor 0x0 product 0x0 version 0x0
Input device name: "Tiny6410 Touchscreen"
Supported events:

      Value      0
      Min        0
      Max     4095

Finally I tried to do "cat /dev/input/event0" and tapped around on the
touchscreen, but this also produced no output. Any help would be greatly
appreciated. Thanks,
