Other Parts Discussed in Thread: MSP430F5438, CC2520

Hi,

I am using MSP430F5438 experimental board with CC2520.

And I am working on zstack sampleapp.

I wish to read the MAC address of device.

I have referred some documents and concluded it is stored in flash memory of host at below address range.

#define HAL_NV_IEEE_ADDR 0x19F8

to 0x19FF

But If I read the value at this address , it will give 0xff in all eight locations.

So it choose randomly some MAC address.

How can I get a unique MAC address of the device?

Hi Keerthi,

Have you tried accessing the NV item ZCD_NV_EXTADDR using Z-Tool?

Hi OD,

Thanks for your reply.

I can access ZCD_NV_EXTADDR from NV memory using z tool.

It gives ,, { 0XFF, 0XFF, 0XFF, 0XFF, 0XFF, 0XFF, 0XFF, 0XFF }

static void zmain_ext_addr(void)

In this function, The Ext address doesn;t read from NV memory.

It choose randomly.
