Calibrating the touchscreen

The calibration only appears the first time you boot Android. The settings are stored on your SD

Card under /data/system/calibration.

● If you want to recalibrate the touchscreen you will need to remove the existing calibration

file. To remove the calibration info insert your SD card into the PC and run the following

commands from a terminal (the actual path might depend on your system):

$ cd /media/data/system

$ sudo rm calibration

● Alternatively, you can use the adb to connect to the board and remove the file from the

debug shell.

adb# rm /data/system/calibration

then reboot.

Configuring the display

The display is configured from the bootloader prompt (to access it, use the serial console

and press "spacebar" when the board starts booting).

4.3" SEIKO 24bpp LCD (MCIMX28LCD)

● This LCD screen is supported by default. If you have changed the settings and need to

set it again, use the following commands:

U-Boot> setenv set_display run lcd

U-Boot> save

● This will save the environment variables to the SD card. Restart the board and Android

will load.

7" CHUNGWA 16bpp LCD

● Use the following commands in U-Boot:

U-Boot> setenv set_display run claa_lcd

U-Boot> save
