uClinux下显示驱动移植及minigui的移植
1
开启uClinux的FrameBuffer支持
1.1
修改/uClinux-dist/vendors/Samsung/44B0/config.linux-2.4.x
确定 CONFIG_VT=y
//VT 应该是Virtual
Terminal
1.2
修改/uClinux-dist/linux-2.4.x/drivers/video/s3c44b0xfb.c
默认情况下是支持16灰度屏的,如果是256色屏,则需要将#define
LCD_GRAY_16 注释掉。
1.3
增加fb0设备
修改vendors/Samsung/44B0/Makefile
1.4
驱动确定

将程序编译进内核
uClinux-dist/romfs/
里的文件是最终生成的内核文件,也是开发板上系统能看到的文件,要将文件编译进内核,只需把文件放到这里就行,然后make
arm-elf-gcc
–elf2flt –o test1 test1.c
arm-elf-gcc
–elf2flt –o test2 test.c
将test1
test2 放到uClinux-dist/romfs/usr/里
Make
两次,我发现make一次没装进去。
内核编译后下载进开发板,进入系统,运行程序就可测出/dev/fb0有没存在,FrameBuffer有没配置成功。

minigui移植
2.1
安装库和资源
1)解压minigui-res-1.6.tar.gz,设置config.linux文件,将编译器设置为arm-elf-gcc。并将安装路径设置为arm-elf-gcc所在的目录。
tar
–zxvf minigui-res-1.6.tar.gz
修改config.linux
prefix
= $(TOPDIR)/usr/local/
CC
= arm-elf-gcc
然后
Make
install
安装到/usr/local/lib/minigui/res
该res
是MiniGUI.cfg
里面资源引用的位置,也是进行移植的资源。
prefix
= $(TOPDIR)/usr/local/arm-elf
CC
= arm-elf-gcc
然后
Make
install
安装到/usr/local/arm-elf/lib/minigui/res
编译器库里的资源
2)解压libminigui-1.6.x-linux.tar.gz,修改编译参数
tar
–zxvf libminigui-1.6.x-linux.tar.gz
修改libminigui-1.6.2-linux/scripts/mkconfig
if
check_value "CONFIG_COMPILER_ARM_ELF"; then
#
CFLAGS="$CFLAGS -D__PIC__ -fpic -msingle-pic-base"
CFLAGS="$CFLAGS
-D__PIC__ -fno-pic -fno-PIC"
Fi
不然在开发板运行程序时会出现如下错误码:

移植配置文件和资源
1)

表示采用Framebuffer,dummy表示没有输入设备,如触摸屏。
