TQ210如何修改LCD分辨率

如题..!!麻烦天嵌技术支持帮忙 ...谢谢！！

先在内核配置单将自适应屏的选项去掉
-> Device Drivers-> Graphics support-> Support for frame buffer devices (FB [=y])-> S3C Framebuffer support (FB_S3C [=y])-> Select LCD Type (<choice> [=y])  
内核源码目录
kernel30/arch/arm/mach-s5pv210/mach-tq210.c
static struct s3cfb_lcd A70_TN92
有这一类的结构体（如果用提7寸屏的就是这个结构休）。
里面有些参数，可以按自己的实际使用屏进行修改。

嗯好的 俺试试 ！

我这里是3.0.6 和 2.6.35.7的内核都没有这个参数!

另外我将struct s3cfb_lcd A70_TM92原800*480 换成了800*600的内容后出现一下bug：

在uboot中配置10.4的屏。重新编译下看它是不是已经使用了800×600的分辨率。如果是旧的，建议在配置单中将分辨率成800×600.如果只是想要16:9的分辨率，建议将分辨率改小，而非改大。
如果还不行可以在drivers/gpu/pvr/pvr_debug.c
IMG_VOID PVRSRVDebugAssertFail(const IMG_CHAR* pszFile, IMG_UINT32 uLine)
{
        PVRSRVDebugPrintf(DBGPRIV_FATAL, pszFile, uLine, "Debug assertion failed!");
//        BUG(); 注释掉
}
drivers/gpu/pvr/pvr_debug.h
//#define PVRSRV_NEED_PVR_ASSERT  注释掉

设置uboot中的10.4寸屏是没有用 后来改了你是活这几个地方是可以...
但是只能显示出800*600 并且很卡...
- -#
调成1028*768显示的效果会和800*600一样...

将s3cfb_lcd A70_TN92结构中修改了
.width=1280,
.height=800,
其他没有动
编译烧录后屏没有一丁点的变化

先在内核配置单将自适应屏的选项去掉
-> Device Drivers-> Graphics support-> Support for frame buffer ...

这个结构体在哪调用啊？  好像没有找到！！
