Hi,
i have a problem with my touchscreen on my EA3250 CPU module. It is not sending any data, you can't use it with e.g. ts-calibrate (no reaction, if you press the touchscreen). Here is a brief history of my activities:
1) Setup the board with the original 2.27 kernel provided by EA. The touchscreen was working fine (->no hardware defect on the board)
2) Flashed the latest Kickstart and S1 loader (V2.0) onto my board
3) Pulled ltib via CVS from the repository (3 days ago) and used the standard settings for the EA3250 target, except that i have disabled audio
4) Compile went smoothless and i have flashed the new u-boot loader onto my board
5) Setup TFTP & NFS and startet the booting process
6) Everything is fine, but i have no functional touchpad... :-(
I have checked, that CONFIG_INPUT_TOUCHSCREEN and CONFIG_TOUCHSCREEN_ADS7846 are set.
The device node /dev/input/event0 does exist (with the parameters c 13 64).
I have attached the boot messages at the end of this mail.
Does anyone has an idea, which configuration is missing or where i should look to debug and/or enable the touchscreen ?
Thanks a lot for your help :-)
Best regards
Arne
