[meta-freescale] Issue calibrating ft5x06_ts

[Mathieu Tétreault]

Hi,

I'm trying to calibrate a ft5x06_ts touchscreen, but the application
fails to detect any input.
Using ts_test and ts_print I'm able to get touchscreen data.

Did any of you had any luck getting ts_calibrate with this driver?

I found some information on TI's website, but it didn't helped.

I exported the following variables.

TSLIB_TSDEVICE=/dev/input/touchscreen0
TSLIB_FBDEVICE=/dev/fb0
TSLIB_PLUGINDIR=/usr/lib/ts
TSLIB_CONFFILE=/etc/ts.conf

QWS_MOUSE_PROTO=Tslib:/dev/input/touchscreen0
