Tiny210 编译Linux3.0.8

一、编译内核

cp mini210-tvp5150_linux_deconfig .config

make

没有出现错误，烧到板上，12寸屏不能显示，修改LCD参数为屏的参数，在arch/arm/mach-s5pv210/mini210-lcds.c

static struct s3cfb_lcd wvga_s70 = {
    .width = 1024,
    .height = 768,
    .p_width = 254,
    .p_height = 184,
    .bpp = 32,
    .freq = 62, 

    .timing = {
        .h_fp = 12,
        .h_bp = 12,
        .h_sw = 4,
        .v_fp = 8,
        .v_fpe = 1,
        .v_bp = 8,
        .v_bpe = 1,
        .v_sw =  4,
    },
    .polarity = {
        .rise_vclk = 0,
        .inv_hsync = 1,
        .inv_vsync = 1,
        .inv_vden = 0,
    },
};

重新编译，OK

2. 编译RootFS

按照Tiny210手册编译，启动出错：can't open /r/dev/console

解决办法：在文件系统/dev下建立console节点，命令为sudo mknod console c 5 1 

3. 修改触摸屏驱动

因为手上的屏是12寸USB接口的超声波触摸屏，Tiny210原先的驱动不适合使用

1. 下载tslib1.4:

git clone https://github.com/kergoth/tslib

2.编译

./autogen.sh
./configure --host=arm-linux --prefix=/opt/tslib CC=/opt/FriendlyARM/toolschain/4.5.1/bin/arm-linux-gcc

make
make install

之前加入--enable-inputapi=no，编译后发现在没有input.so

3. 复制/opt/tslib目录到RootFS相应目录下

4. 修改tslib/etc/ts.conf,去掉module_raw input面前的井号及空格,行首不要留有空格

5. 修改/etc/profile,在后面加入如下代码(event2是我的输入设备):

export TSLIB_ROOT=/opt/tslib
export TSLIB_TSDEVICE=/dev/input/event2
export QWS_MOUSE_PROTO=tslib:/dev/input/event2
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=$TSLIB_ROOT/etc/ts.conf
export TSLIB_PLUGINDIR=$TSLIB_ROOT/lib/ts

6. 在命令行下直接转入ts_calibrate,发现每次都提示校正失败,后面发现ts_calibrate是直接调用/bin/ts_calibrate,那是系统原来的,不适合这里使用,真正有用的是/opt/tslib/bin/ts_calibrate

7.修改/bin/qt4以适应我们的触摸屏,修改后的如下

#!/bin/sh

#if [ -e /etc/friendlyarm-ts-input.conf ] ; then
#	. /etc/friendlyarm-ts-input.conf
#fi
#true	${TSLIB_TSDEVICE:=/dev/touchscreen}

#if grep -Ei "<ctp=(1|2|3)>" /proc/cmdline >/dev/null; then
#	TSLIB_CONFFILE=/etc/ts-mt.conf
#else
#	TSLIB_CONFFILE=/etc/ts.conf
#fi

#export TSLIB_TSDEVICE
#export TSLIB_CONFFILE

#export TSLIB_PLUGINDIR=/usr/lib/ts
#export TSLIB_CALIBFILE=/etc/pointercal

export QWS_DISPLAY=:1
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
export PATH=/bin:/sbin:/usr/bin/:/usr/sbin:/usr/local/bin

if [ -c ${TSLIB_TSDEVICE} ]; then
	export QWS_MOUSE_PROTO="Tslib MouseMan:/dev/input/mice"
	if [ ! -s /etc/pointercal ] ; then
		rm /etc/pointercal
		#/usr/bin/ts_calibrate
		/opt/tslib/bin/ts_calibrate
	fi
else
	export QWS_MOUSE_PROTO="MouseMan:/dev/input/mice"
fi

export QWS_KEYBOARD=TTY:/dev/tty1

export HOME=/root

cd /usr/local/Trolltech/QtEmbedded-4.7.0-arm/demos/embedded/fluidlauncher
./fluidlauncher -qws
hotplug

8. 输入 qt4看看修改是否成功
