calibration support in the ti_tsc.c

Hi all,

I am working on bbb custom board which is running on android jb 4.2.2(kernel version 3.2). Android source coded downloaded from the rowboat repo.

Board interfaced with resistive touch screen. I am not getting the touch screen calibration option in the first boot.

By default the touch screen calibration option would be disabled ?

If I want to enable this option what and all needs to be done.

The Android source code has tslib in the external directory.  I could n't find any driver support in the ti_tsc. kernel driver file.

Is there any driver patch is available to support the calibration? Please help me out in this regard.

Thanks in advance.

    Hi,

    This forum supports TI Linux SDKs and HW related questions only.

    Generally (in linux sdks) you should add the ts-calibrate in etc/init.d folder. Then you should also add a script that calls the ts-calibrate in /etc/rcX.d folders, in linux sdk the ts-calibrated is called through S96ts-calibrate & is called from withing rc2.d, rc3.d, rc4.d & rc5.d.

    For more detailed explanation on how things are setup in Android, you should direct this question to the Android forum: e2e.ti.com/.../509 ?

    Best Regards,
    Yordan
