TI中文支持网TI工程师您好：
cc2530，版本2.5.1a，我想用HalFlashWrite来改写secondary MAC。发现调用HalFlashWrite写了，但从打印来看，没写成功。
HalFlashWrite(uint16 addr, uint8 *buf, uint16 cnt)中的addr和cnt均是按除4来处理的，请问还有什么地方需要注意吗？
直接在zmain_ext_addr中增加调试代码如下：
static void zmain_ext_addr(void)
{
uint8 nullAddr[Z_EXTADDR_LEN] = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF};
uint8 writeNV = TRUE;
uint8 locbit[HAL_FLASH_LOCK_BITS] = {0};
uint8 testMac[Z_EXTADDR_LEN] = {0};
uint8 testMac2[Z_EXTADDR_LEN] = {0x12,0x34,0x56,0x78,0x9A,0xAB,0xCD,0xEF}; uint8 strTemp[100]={0};
HalUARTWrite(1, "[MAC_01]\r\n", osal_strlen("[MAC_01]\r\n"));
#if defined NON_BANKED
HalUARTWrite(1, "[MAC_02]\r\n", osal_strlen("[MAC_02]\r\n"));
#endif
#if 1 osal_memset(locbit,0,16);
memset(locbit,0,HAL_FLASH_LOCK_BITS);
HalFlashRead(HAL_FLASH_IEEE_PAGE, (HAL_FLASH_IEEE_OSET+HAL_FLASH_IEEE_SIZE), locbit, HAL_FLASH_LOCK_BITS);
osal_memset(strTemp,0,100);
sprintf((char *)strTemp, "\r\n[MAC_00001:%02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x]\r\n"

1、smartrf flash programmer修改是否成功?
2、HalFlashWrite的使用请参考：

smartrf flash programmer修改可以成功，但直接通过HalFlashWrite不成功。
换了台设备，似乎第1次调用HalFlashWrite可写成功，后续修改参数后再写就不成功了。
请问HalFlashWrite是有这个限制只允许写1次吗？
另smartrf flash programmer写secondary MAC的代码在什么地方？[MAC_01]
[MAC_00001:FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF]
[MAC_00002:12 34 56 78 9A AB CD EF]
[MAC_00003:12 34 56 78 9A AB CD EF]—正确
[MAC_07:CB 3D 62 1A 00 4B 12 00]
[Uart1 init1019]
[MAC_01][MAC_00001:FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF]
[MAC_00002:12 34 56 78 9A AB CD EF]
[MAC_00003:10 20 12 78 9A AB CD EF]—不正确，此时我换成了 11 22 33 78 9A AB CD EF
[MAC_07:CB 3D 62 1A 00 4B 12 00]

知道原因了。操作前需调用HalFlashErase。
擦除是以1个page(2048字节)为单位的，这个page内还有许多其它信息，如先将page读出到SRAM，在SRAM修改后再整个page写入，可是SRAM才8K（已用了很多，剩余不够2K），请问有什么好的方法推荐？
