WinCE50 桌面花屏

Synwell 2012-02-26 02:16:56
WinCe50 在ATMEL ARM9上开发，出现桌面花屏，请教高手，可能什么原因，谢谢！启动过程出现Windows CE logo也有花屏，上面有一些小黑点和斜线。

显示是OLED屏，类似NAND FLASH操作，原来跑Vxworks，用ZINC显示也正常。

如果是VGA显示器，建议用电脑显示器先试试，如果行，则你的工控机显示驱动可以找厂家帮忙

我的另外一个板子也是这种情况。只不过不是很严重的。
就是在启动的时候出现出现白屏还有点闪。很短的时间就没有了
不知道是那的。感觉是硬件的问题

用 Remote Zoomin 工具抓图是黑屏，但设备上是有图像的。我是用KITL和CESH和设备连的。

这个怎么查呀，跪求高手指点。谢谢！

谢谢楼上两位，应该吧不是硬件的问题，因为EBOOT显示时，显示的图像和我的预计相同。Wince驱动中传输图像前执行的函数BltPerpare和传输结束时的执行函数BltComplete如下：
BltPrepare(GPEBltParms *blitParameters)
{
RECTL rectl;
UINT16 left,top,right,bottom;

// RETAILMSG(1, (TEXT("BltPrepare\r\n")));


// default to base EmulatedBlt routine
blitParameters->pBlt = EmulatedBlt;

// see if we need to deal with cursor
if (m_CursorVisible && !m_CursorDisabled)
{
// check for destination overlap with cursor and turn off cursor if overlaps
if (blitParameters->pDst == m_pPrimarySurface) // only care if dest is main display surface
{
if (blitParameters->prclDst != NULL) // make sure there is a valid prclDst
{
rectl = *blitParameters->prclDst; // if so, use it
}
else
{
rectl = m_CursorRect; // if not, use the Cursor rect - this forces the cursor to be turned off in this case
}


if (m_CursorRect.top < rectl.bottom && m_CursorRect.bottom > rectl.top &&
m_CursorRect.left < rectl.right && m_CursorRect.right > rectl.left)
{
CursorOff();
m_CursorForcedOff = TRUE;
}

left=(UINT16)rectl.left;
top=(UINT16)rectl.top;
right=(UINT16)rectl.right;
bottom=(UINT16)rectl.bottom;

RETAILMSG(1, (TEXT("BltPrepare:window (%d,%d,%d,%d)\r\n"),left,top,right,bottom));

left=left<320? left : 0;
OledSetWindow(left,top,right-1,bottom-1);
OledSetGramStart();

}

// check for source overlap with cursor and turn off cursor if overlaps
if (blitParameters->pSrc == m_pPrimarySurface) // only care if source is main display surface
{
if (blitParameters->prclSrc != NULL) // make sure there is a valid prclSrc
{
rectl = *blitParameters->prclSrc; // if so, use it
}
else
{
rectl = m_CursorRect; // if not, use the CUrsor rect - this forces the cursor to be turned off in this case
}
if (m_CursorRect.top < rectl.bottom && m_CursorRect.bottom > rectl.top &&
m_CursorRect.left < rectl.right && m_CursorRect.right > rectl.left)
{
CursorOff();
m_CursorForcedOff = TRUE;
}

} }


// see if there are any optimized software blits available
EmulatedBltSelect02(blitParameters);
EmulatedBltSelect08(blitParameters);
EmulatedBltSelect16(blitParameters);
// RETAILMSG(1, (TEXT("-BltPrepare\r\n")));

return S_OK;
}

BltComplete(GPEBltParms *blitParameters)
{
// RETAILMSG(1, (TEXT("BltComplete\r\n")));

// see if cursor was forced off because of overlap with source or destination and turn back on
if (m_CursorForcedOff)
{
m_CursorForcedOff = FALSE;
CursorOn();
}
OledSetGramEnd();

#if 1 //Test
RETAILMSG(1, (TEXT("TestCount=%d\r\n"),TestCount));
TestCount++;
// if(TestCount>170)
// while(1);

#endif //End Test

return S_OK;
}

执行结果如下：

而且红色部分代码没有不被执行一次。

试用版不会有这个问题吧？

如 LS 所说，先排除硬件的问题

再查软件/驱动。可以考虑先用 Remote Zoomin 工具抓图来看看显示是否正确。
