我准备把红外遥控解码后，写入eeprom，再读出，然后输出。我的程序会在下方列出，我的程序调试后，发现单个程序没错，几个程序和到一块，在运行printf。。。后L107：adress space overflow地址溢出,SPACE：DATA位置在数据处，主要程序下面列出：

其中initUart(); /* 初始化串口 */ 是：
void initUart(void)/*初始化串口波特率，使用定时器2*/
{
/* Setup the serial port for 9600 baud at 11.0592MHz */
SCON = 0x50; //串口工作在方式1
TMOD=0x20;//定时器1工作了方式2;
PCON=0x00;//SMD=0
TH1=0xFD;
TL1=0xfd;
TR1 = 1;//启动定时器
TI=1;/* 置位TI注意如果此位的作用是发送中断请求位，只有在置一后才可以发送数据*/
}
