GernericEBOOTutils.c文件報(bào)error C2220: warning treated as error - no 'object' file generated錯(cuò)誤

解決辦法：將該文件另存為unicode編譯格式

2 WINCE600PLATFORMAT91SAM9261EKSRCBOOTLOADERFirstBootdbgu.h文件里的#define TIME_OUT_CHAR '?報(bào)error C2001: newline in constant錯(cuò)誤

解決辦法：將#define TIME_OUT_CHAR '?改為#define TIME_OUT_CHAR '?'

3 開機(jī)花屏

原因：在LCD驅(qū)動(dòng)中只申請(qǐng)了地址空間，沒有對(duì)顯存進(jìn)行初始化，代碼在E:WINCE600PLATFORMAT91SAM9261EKsrcDRIVERSAT91SAM9261DisplayGraphic.cpp

GPE* GetGPE()函數(shù)的以下代碼中

if ( RegQryValEx(hKey, L"VRAMAddress", 0, &dwType, (LPBYTE)&dwVideoMemStartAddress, &dwBLen) != ERROR_S?SS )

{

// Allocate a bfer in common SDRAM

dwVideoMemSize = dwVideoMemWidth * dwVideoMemHeight * dwBpp/8;

VA_VideoMem = HalAllocateCommonBfer(&myDmaAdapter, dwVideoMemSize, &PA_VideoMem, false);

dwVideoMemStartAddress = PA_VideoMem.LowPart;

DEBUGMSG(GPE_ZONE_HW, (TEXT("Video memory %d kB in SDRAM"), dwVideoMemSize /1024));

}

解決辦法：

1）將if條件注掉，在大括號(hào)內(nèi)初始化系統(tǒng)分配的顯存

{

// Allocate a bfer in common SDRAM

dwVideoMemSize = dwVideoMemWidth * dwVideoMemHeight * dwBpp/8;

VA_VideoMem = HalAllocateCommonBfer(&myDmaAdapter, dwVideoMemSize, &PA_VideoMem, false);

dwVideoMemStartAddress = PA_VideoMem.LowPart;

DEBUGMSG(GPE_ZONE_HW, (TEXT("Video memory %d kB in SDRAM"), dwVideoMemSize /1024));

unsigned int cnt;

for(cnt=0;cnt

{

*(unsigned char*)((unsigned int)VA_VideoMem+cnt) = 0;

}

}

2)將注冊(cè)表中的物理地址映射成虛擬地址,再初始化
