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

Other Parts Discussed in Thread: TM4C129XNCZAD

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"
