LCD8000-70T Display Configuration
1）The connection of LCD8000-70T and RIoTboard will be finished through the LCD-Ex
extension board, the way of which can be seen as below:
Figure 1 Hardware Connections
Mote:
On using 50PIN FPC cable to connect LCD and LCD-Ex, the blue side should be
upward;
It does not support the powered plug-in and plug-out.
2）Please connect the red, green and black wires of UART8000-U respectively to the
corresponding pins of J18 connector on RIoTboard as illustrated in the following
figure;

5）Set the display mode
Under the u-boot, 7-inch LCD display mode can be set by executing the
following instructions:
MX6Solo RIoTboard U-Boot > setenv bootargs console=ttymxc1,115200
init=/init nosmp video=mxcfb0:dev=lcd,7inch_LCD,if=RGB565
video=mxcfb1:off fbmem=10M vmalloc=400M androidboot.console=ttymxc1
androidboot.hardware=freescale calibration
MX6Solo RIoTboard U-Boot > saveenv
6）Set the touch screen
Ubuntu
a) On entering the system, the following command can be used to unload
synaptics driver
root@linaro-ubuntu-desktop:~# sudo apt-get remove
xserver-xorg-input-synaptics
b) Input the following instructions to install tslib
root@linaro-ubuntu-desktop:~# sudo apt-get install
xserver-xorg-input-tslib libts-bin
At the execution of this command, network needs to be connected. In
additional, you can download ubuntu-touchscreen.zip from Embest
website to install tslib. On unzipping, copy to U-disk and connect

U-disk to RIoTboard. Then execute the following instructions:
root@linaro-ubuntu-desktop:~# dpkg -i libts-bin_1.0-9_armel.deb
root@linaro-ubuntu-desktop:~# dpkg -i
xserver-xorg-input-tslib_0.0.6-7_armel.deb
c) Restart the development board and execute the following instructions
after entering the system:
root@linaro-ubuntu-desktop:~# TSLIB_TSDEVICE=/dev/input/event0
root@linaro-ubuntu-desktop:~# TSLIB_CONFFILE=/etc/ts.conf
root@linaro-ubuntu-desktop:~# export TSLIB_TSDEVICE
TSLIB_CONFFILE
root@linaro-ubuntu-desktop:~# ts_calibrate
# At this time a calibration interface will pop up on the screen. Finish
the calibration as per the prompt
root@linaro-ubuntu-desktop:~# sync
d) Restart the development board and the touch screen can be used
normally.
Android
Keep on starting after the display has been set, the system will automatically pop
up the calibration interface, touch all the “+” marks on the screen by following the
information shown on the screen to finish calibration.
LCD8000-43T which is used in the Android system before now will be displaced
by LCD8000-70T now. After the 7-inch LCD display mode has been set, the
following instructions need to be executed when you enter the system:
root@RIoTboard_6solo:/ # rm /data/system/calibration
root@RIoTboard_6solo:/ #sync
Then restar t the development board and re-calibrate the touch screen.
