1 WINCE600\PLATFORM\COMMON\SRC\SOC\ATMEL\COMMON\BOOTLOADER
GernericEBOOT\utils.c文件报error C2220: warning treated as error - no
'object' file generated错误
解决办法：将该文件另存为unicode编译格式
2 WINCE600\PLATFORM\AT91SAM9261EK\SRC\BOOTLOADER\FirstBoot\dbgu.h文件里的#define
TIME_OUT_CHAR '?报error C2001: newline in constant错误
解决办法：将#define TIME_OUT_CHAR '?改为#define TIME_OUT_CHAR '?'
3 开机花屏
原因：在LCD驱动中只申请了地址空间，没有对显存进行初始化，代码在E:\WINCE600\PLATFORM\AT91SAM9261EK\src\DRIVERS\AT91SAM9261Display\Graphic.cpp
GPE* GetGPE()函数的以下代码中
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));
}
解决办法：
1）将if条件注掉，在大括号内初始化系统分配的显存
{
// 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<dwVideoMemSize;cnt++)
{
*(unsigned char*)((unsigned int)VA_VideoMem+cnt) = 0;
}
}
2)将注册表中的物理地址映射成虚拟地址,再初始化。我用的是方法1，方法2一定可以，但我没试过。
