How to access Hardware Serial Number

brian_ungar — Tue, 16 Aug 2022 02:11:27 GMT

I am running software on an LPC54S018 board. Is there a way to obtain the serial number of the card via an API call from somewhere in the SDK?

Hi,

You can read the UUID which can be viewed as serial number.

For detailed inf, pls refer to the section 6.4.5.8 ISP Read UUID in UM11155.pdf, which can be downloaded from the link:

https://www.nxp.com/webapp/Download?colCode=UM11155&location=null

There is also ID number for the LPC family, pls refer to section 8.5.99 Device ID0 register

Hope it can help you

The ID that you reference is for the USART. I want to access (via an SDK API) the unique information about the board (LPCXpresso54S018).

Hi,

Regarding your question about the unique information about the board (LPCXpresso54S018), i suppose there is NOT unique information about the LPCXpresso54S018, all boards are the same.

Hope it can help you
