As for Allwinner H2+/H3/H5/ SoCs each of these CPUs has an internal 16-btye CHIP ID which can be read by running the following commands in the Linux-4.14 kernel:

$ apt-get install bsdmainutils
$ hexdump /sys/bus/nvmem/devices/sunxi-sid0/nvmem 
0000000 8082 0447 0064 04c3 3650 ce0a 1e28 2202
0000010 0002 0000 0000 0000 0000 0000 0000 0000

2 Boot System from SSD

A NanoPi-Duo can be booted from the SSD on a Mini Shield for NanoPi Duo. Booting OS from an SSD has the following benefits:
1) faster read/write;
2) much longer life time than a TF card;
3) more reliable than booting from a TF card;

You can install an OS to SSD by using the npi-config utility. Here are the steps to follow:

sudo npi-config

Enter the "Boot Options" menu, go to "Boot device" and you will see two options:
1) D1 Hard drive
2) D2 TF card
Select "D1 Hard drive" and proceed with its prompts.
Select "D2 TF card" to boot OS from a TF card.

If your npi-config doesn't have a "Boot device" menu it might be that your npi-config is out of date and you can update it by selecting "Update" in the menu.
