Input these command on the board console
# vi /etc/init.smdk4x12.sh
(Add the following contents at the last of the file)
busybox ifconfig eth0 down
busybox ifconfig eth0 hw ether 00:11:22:33:44:55
busybox ifconfig eth0 up
Save and quit, reset the board.
Actually boot animation under the Android is formed by plenty of pictures take turns to play.
First of all, make bootanimation.zip according following steps.
1. Edit the file “desc.txt” under the Linux
800 480 2
p 1 0 part0
p 0 0 part1
Create two new folders such as “part0” and “part1”, then put the images (PNG) into the two new folders “part0” and “part1” according to the broadcast order respectively.
2. Packaging under the window. Select the files of “desc.TXT”, "part0”, "part1”, choose "zip" compressed format, please select "storage" compression way. (On the other hand, you can also execute the command “zip” to packag under the Linux)
At last, move the file “bootanimation.zip” to the directory of “system/media” or “data/local”.
Please refer to the corresponding user manual.
For example em210 of android4.0.3 platform:
Configuration 7-inch resistive screen, you only need to modify the environment variables of uboot. The settings are shown as follow.
# setenv bootargs console=ttySAC2,115200 init =/init lcd=S70
# save
If you want to configure a 7-inch capacitive screen, then you have to modified kernel configuration options on the base of the which support the original 7-inch resistive screen.
Choose support “TOUCHSCREEN_S3C_CAPACITIVE”, execute the command “make menuconfig”, then setting according to the following directory: Device Drivers -> Input device support -> Touchscreens -> S3C capacitive touchscreen driver
