4.3寸屏幕 TQ2440_Test.bin 烧写到板子里运行的时候，天嵌的logo（Lcd_TFT_Test最后一屏）中间显示很大的白色矩形，屏幕底下的图错位了。。。是什么原因造成的呢？改了好久都没改出来，我把开机第一屏的条形图也改成天嵌logo ，出现了一样的问题，看着又显不像是函数的问题。。。上面那个图是显示的图片，官方编译好的bin文件烧进去也是这样的问题。。
附上画图的函数
void Paint_Bmp(int x0,int y0,int h,int l,unsigned char bmp[])
{
   int x,y;
   U32 c;
   int p = 0;

for( y = y0 ; y < l ; y++ )
{
         for( x = x0 ; x < h ; x++ )
         {
               c = bmp | (bmp<<8) ;

                     if ( ( (x0+x) < SCR_XSIZE_TFT) && ( (y0+y) < SCR_YSIZE_TFT) )
                           LCD_BUFFER = c ;

               p = p + 2 ;
         }
}
}

函数都是官方出厂时的函数，没改过，官方编译好的bin文件烧进去也是这样的问题。。

你是烧到nand中测试还是是直接烧SDRAM里边？烧nand的话如果你的镜像编译出来比较大就修改下nand.c中的RdNF2SDRAM函数，把size改大点试试

bin文件编译出来是538k

画图函数本身没有问题哦。这个问题你可以这样试试。下载到ＮＡＮＤ中，然后从ＮＡＮＤ启动。一般就没问题了。还有你的主函数显示语句要给我们看看啊。。。。

http://bbs.embedsky.net/data/attachment/forum/201203/06/1903185x33ngnu53v4ttyp.jpg函数是官方工程文件里的，没有改过。。
我烧写的时候是在串口命令下按 a 用 usb 烧入的，这个有影响么？dnw 设置是波特率115200下载地址是0x30000000

as12312a 发表于 2012-3-6 20:18:25

我烧写到sdram里面运行，发现图片可以显示了、、这是怎么回事呢？

as12312a 发表于 2012-3-6 20:55:19

我知道怎么回事了，我烧写bin文件到nand flash时未格式化nand flash，格式化后再烧写，图片完美显示！！

as12312a 发表于 2012-3-6 20:55:59

感谢版主热心帮忙解决问题

tigerdawn 发表于 2012-3-28 20:33:31

兄弟知音哪，我今天也是这个问题，纠结了好半天，一直以为取模软件出了问题呢，直到看见了这贴！
