void memory_test(void)
{
int i;
UINT32T data;
int memError=0;
UINT32T *pt;
// memory test
uart_printf("\nMemoryTest(%xh-%xh):WR\n", _RAM_STARTADDRESS+0xe00000,
(_ISR_STARTADDRESS&0xf0ff0000)); /*打印出内存测试函数所覆盖地址1-地址2的范围*/
//memory write
pt=(UINT32T*)(_RAM_STARTADDRESS+0xe00000);/*指针pt指向地址1*/
while((UINT32T)pt<(_ISR_STARTADDRESS&0xf0ff0000))
{
/*向内存地址中不断写入其地址值的内容
假设现在地址是0x2000 1000这个地方写上一个叫做0x2000 1000的值
再在地址是0x2000 1004这个地方写上一个叫做0x2000 1004的值
以此类推

*/
*pt=(UINT32T)pt;
pt++;
}/*全部写完*/
//MEMORY READ
uart_printf("MemoryTest(%xh-%xh):RD\n", _RAM_STARTADDRESS+0xe00000,
(_ISR_STARTADDRESS&0x0f0ff0000));/*打印出需要读取内容的地址范围，地址1-地址2*/
//uart_printf("\b\bRD");
pt=(UINT32T*)(_RAM_STARTADDRESS+0xe00000);/*用指针pt指向地址1*/
/*将地址1-地址2的内容依次以32位取出*/
while((UINT32T)pt<(_ISR_STARTADDRESS&0xf0ff0000))
{data=*pt;/*取出pt指针所指向地址的内容*/
if(data!=(UINT32T)pt)/*判断该内容是否为其地址值*/
{memError=1;
uart_printf("\b\bFAIL:0x%x=0x%x\n",i,data);/*不等，则测试失败*/
break;}
pt++;}
if(memError==0)
uart_printf("\n\b\bO.K.\n");}/*地址1-地址2中的内容全为其地址值，测试成功*/
