Hi
I am building minimal-image for imx6dlsabresd.
Build Configuration:
BB_VERSION = "1.22.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "Ubuntu-12.04"
TARGET_SYS = "arm-poky-linux-gnueabi"
MACHINE = "imx6dlsabresd"
DISTRO = "poky"
DISTRO_VERSION = "1.6"
TUNE_FEATURES = "armv7a vfp neon callconvention-hard cortexa9"
TARGET_FPU = "vfp-neon"
meta
meta-yocto
meta-yocto-bsp = "daisy:62b1fef7875a6f9c55344fa6bcc7d4b6672eac1f"
meta-oe = "daisy:dca466c074c9a35bc0133e7e0d65cca0731e2acf"
meta-fsl-arm = "daisy:f5bf277a5a5fba2c3b64ed7d2dbec1903d96386b"
meta-fsl-demos = "daisy:27fdb2f2642ecd55d5633bde880dd4c37acd0d42"
When I used branch dora the tslib and ts_calibrate worked.
Now using daisy ts_calibrate doesn't work, ts_print doesn't work, only
ts_print_raw is working.
It has set by default TSLIB_TSDEVICE=/dev/input/touchscreen0
I added some debug information into tslib and discovered that the
pressure signal is missing so probably the problem is the kernel
settings (maybe a misconfiguration in DT).

What have you changed in daisy or linux-3.10.17 that broke the touchscreen?
Anybody tested the new image with a imx6dlsabresd?
What do you think?
TIA
