急！TI 的Tiva™ TM4C129X Development Board ， EEPROM用不了，下载不了程序

我用的是TI 原装的Tiva™ TM4C129X Development Board， 芯片是tm4c129xnczad。

想用ARM里的内置EEPROM存储一些东西，从板子带的例子uart echo改的。

发现调用

SysCtlPeripheralEnable(SYSCTL_PERIPH_EEPROM0);

ROM_EEPROMInit();

//ROM_EEPROMProgram(pui32Data, 0x100, sizeof(pui32Data));

//ROM_EEPROMRead(pui32Read, 0x100, sizeof(pui32Read));

根本无法操作EEPROM，而且程序反复出现下列情况：

（1）程序跑飞

（2）如果再重新下载程序，就出现,下载不了程序

具体程序如下

#include <stdint.h>

#include <stdbool.h>

#include "inc/hw_ints.h"

#include "inc/hw_gpio.h"

#include "inc/hw_memmap.h"

烧个EEPROM的例程试试
