Zigbee 修改物理地址IEEE address

参考C:\Texas Instruments\ZStack-CC2530-2.5.1a\Documents   Z-Stack User's Guide - CC2530DB 可知

The Secondary IEEE address location is found on the last page of the CC2530 flash memory, at an offset of 0x0018 bytes from the last memory address. For a 256-Kbyte device, the IEEE address can be commissioned at 0x3FFE8-0x3FFEF.

您可以通过FLASH写入。关于协议里面存放IEEE的地址，和使用的逻辑请再搞清楚下。

1）首先CC2530里面有两个IEEE地址，一个Primary IEEE地址，还有一个Secondary IEEE地址。这个你应该知道的。

2）Primary IEEE是放在Info Page里面，用户只能读，没办法写。Secondary IEEE是可以读也可以写的

3）协议栈第一次启动的时候，会去Secondary IEEE和Primary IEEE地址里面挑选一个，作为该设备的MAC 地址，然后写到NV里面。

所以整个CC2530程序跑起来以后，有三个地方存放了IEEE地址，分别是Primary IEEE 在info page里面。 Secondary IEEE在Flash里面，MAC Address 在NV Flash里面。其中MAC Address是选择Primary和Secondary的某一个。至于怎么选的逻辑上面的程序很清楚了。

4）协议栈在第一次启动的时候，首先会判断NV里面有没有，如果没有的话就去Primary和Secondary里面挑了，所以你改的代码是没有用的，因为前天通过挑选已经挑选好了，并且放到NV去了，你的代码根本不会执行到。

所以建议做下面的修改，

在刚进入的zmain_ext_addr(void)的时候，利用Flash的 Write函数，也就是HalFlashWrite，往HAL_FLASH_IEEE_PAGE, HAL_FLASH_IEEE_OSET地方，写进入8个字节的数据就可以了。

当然如不你不用代码操作，你也可以用SmartRF Flash Programmer来写也可以的。
