我的板子一片C6678外挂了4片三星公司的DDR3，最近参考DDR3初始化手册更改一下初始化参数，在进行DDR3读写测试的时候，发现地址线读写出错，而DDR3内存读写正确，百思不得其解，希望大神能够帮忙分析一下，下面是我改写的测试代码，不知道有没有什么问题。
int DataPatternTest(unsigned int uiStartAddress, unsigned int uiCount, unsigned int uiStep) { unsigned int i, j; volatile unsigned long long *ulpAddressPointer; volatile unsigned long long ulReadBack; for(i = 0; i < PATTERN_SIZE; i++) { /* Write the pattern */ ulpAddressPointer = (unsigned long long *)uiStartAddress; for(j = 0; j < uiCount; j++) { *ulpAddressPointer = ulDataPatternTable[i]; ulpAddressPointer += (uiStep); } /* Read back the data*/ ulpAddressPointer = (unsigned long long *)uiStartAddress; for(j = 0; j < uiCount; j++) { ulReadBack = *ulpAddressPointer; if(ulReadBack != ulDataPatternTable[i]) return 0; ulpAddressPointer += (uiStep); } } return 1; } int AddressTest(unsigned int uiStartAddress, unsigned int uiCount, unsigned int uiStep) { unsigned int i; volatile unsigned long long *ulpAddressPointer; volatile unsigned long long ulReadBack; ulpAddressPointer = (unsigned long long*)uiStartAddress; for(i = 0; i < uiCount; i++) { /* fill with address value */ *ulpAddressPointer = _itoll(((unsigned int)ulpAddressPointer)+4,(unsigned int)ulpAddressPointer); ulpAddressPointer += (uiStep); } ulpAddressPointer = (unsigned long long*)uiStartAddress; for(i = 0; i < uiCount; i++) { ulReadBack = *ulpAddressPointer; if(ulReadBack != _itoll(((unsigned int)ulpAddressPointer)+4,(unsigned int)ulpAddressPointer)) return 0; ulpAddressPointer += (uiStep); } return 1; }
