Part Number: AWR1642

Hi all：

Refer to the description in the manual：

We can get the chip UID in the reg.But when I'm debuging,the value is 0.

And how to read the AWR1642 chip UID?Is this UID unique per chip?

Thanks！

Hello Terrell,

Yes, the UID is unique per chip.

Address of registers as seen from the MSS is: 0xFFFFE200, 0xFFFFE204, 0xFFFFE208, 0xFFFFE20C.

May I know why you're using 0xFFFFE300?

Regards,

Ishita

Hi Ishita：

Refer to the description in the manual：

#define SOC_XWR16XX_MSS_TOP_RCM_BASE_ADDRESS 0xFFFFE100U

I see the addr of MSS_TOPRCM is 0xFFFFE100,and the offset addr of UID0-31 is 0x200.

So I think the addr of UID0-31 is 0xFFFFE300.

Thanks!

Hello Terrell,

The correct register address for getting the die ID is what I mentioned in my previous reply.

The 4 UID registers that you have mentioned are used for authorization in case of secure devices. I understand the description in the TRM can be misleading, thanks for the feedback.

Please use the below address :

0xFFFFE200, 0xFFFFE204, 0xFFFFE208, 0xFFFFE20C

Ishita
