8.1. Serial Number

Each TIGER SOM-RK3588-Q7 has a unique serial number that can be read by software.

In U-Boot, the serial number is contained in the environment variable serial#. You can print it using the command:

printenv serial#

Under Linux, it is represented by a simple text file in /sys:

cat /sys/firmware/devicetree/base/serial-number

The serial number is fixed in hardware (derived from the SoC CPU ID) and cannot be modified.
