Question to listen to PC's input and store

I've bought an LPC54S018-EVK board, and I'm trying to listen to PC's input.

So now, how can I make my board receive PC's input and store it into the board?

Is threr any demo code that I can refer to? I haven't found any in LPC54S018-EVK's SDK. 

Thanks a lot!

I think you need to describe your problem with a few more words....

For example, what is "PC's input" ????

Sor, I'll make it clearer.

Imagine a scene, my board has a AES function that generates cipher of a given plaintext.

Now I connect my board to my PC using debug link, and I want the board to listen to PC's messages that give to the board by UART as plaintext.

And since the key for AES is generated by PUF related functions on board, I have to store the key into the board itself.

How can I meet such requirements?

Hi 

The PUF generated key is sent to Hash Crypt engine or PRINCE through internal hardware bus. It is not readable by software. We can only get activation code (AC) which is used for PUF generating KEY. 

It's not possible to print PUF generated KEY to external.

Thanks,
