win驱动移植linux,LCD移植 - 基于Tiny210v2的Linux-3.9.6内核驱动移植_Linux编程_Linux公社-Linux系统门户网站...
友善的tiny210v2我买的是7寸电容屏，具体型号得再查查，说是S70.
用原本的LINUX内的SMDKV210的LCD驱动能实现LINUX LOGO的输出，但是有一定的偏差。
主要参考：
arm9home.net/read.php?tid=27609
环境：
Ubuntu 13.04
内核：
LINUX-3.9.6

//=================================================//
八、修改driver/video/Kconfig
添加
config FB_S3C_DEFAULT_WINDOW
int "DefaultWindow (0-4)"
range 04
depends onFB_S3C
default"2"
---help---
This indicates the default window number, andwhich is used as console framebuffer
config FB_S3C_NR_BUFFERS
int "Numberof frame buffers (1-3)"
depends onFB_S3C
default"2"
---help---
This indicates the number of buffers for pandisplay,
1 means no pan display and
2 means the double size of video buffer will beallocated for default window
config FB_S3C_NUM_OVLY_WIN
int "Numberof overlay window (0-3)"
range 03
depends onFB_S3C
default"1"
---help---
This indicates the number of overlay windows forvideo rendering
config FB_S3C_NUM_BUF_OVLY_WIN
int "Numberof buffers for overlay window (2-3)"
range 23
depends onFB_S3C
default"3"
---help---
This indicates the number of buffers for overlaywindows
最后make,测试ing
