SPI AT45DB161D 的读写怎么换页啊，实现页与页之间连续的读写啊？

最近在用STM32F107 调试AT45DB161D，SPI通信的，代码参考了《My_App 红牛开发板(STM32F103ZET6)读写AT45DB161D 串行Flash测试程序》，结果发现在进行读写测试时，地址累加到528时，读写就出错了，不懂这要怎么解决啊，求老司机带带我~~，下面是测试程序和调试结果。

char Rbuf[500]="";
uint32_t addr = FLASH_WriteAddress;
SPI_FLASH_PageErase(FLASH_SectorToErase);                   // 全部擦除
delay_ms(10);

while(1)
{
len = sprintf(Wbuf,"%d&",addr);
printf("W:[0x%06X][%s]\t->",addr,Wbuf);
SPI_FLASH_BufferWrite((uint8_t *)Wbuf, addr, len);

memset(Rbuf,0,sizeof(Rbuf));
SPI_FLASH_BufferRead((uint8_t *)Rbuf, addr, sizeof (Rbuf));
printf("R:[%s]\r\n",Rbuf);

if(strcmp(Rbuf, Wbuf) != 0) break;
addr++;
}
}

int main(void)
{
delay_init();//延时函数初始化
usart1_Configuration(115200);
printf("\r\n------------------------------------\r\n");

SPI_FLASH_Init();
FLASH_ID = SPI_FLASH_ReadID();
if (FLASH_ID == AT45DB161D_FLASH_ID){
printf("校验OK.\r\n");
}else {
printf("校验Error.\r\n");
}
test();
while (1) ;
}
