Detect the NVIDIA Jetson Nano model


Sometimes, you get one ssh access to a device, and you want to confirm that you are connected to one NVIDIA Jetson Nano.

NVIDIA Jetson Nano is an embedded system-on-module (SoM), instead of using one screwdriver to get the module details, we can try to use software tools.

☒ dmidecode

Most of the time I’m using dmidecode to identify my hardware server type, but ARM is not standardized as x86 platforms.

When you try to use dmidecode on Jetson Nano, you’ve got an error:

[email protected]:~$ sudo dmidecode 
# dmidecode 3.1
# No SMBIOS nor DMI entry point found, sorry.

dmidecode is a tool for dumping a computer’s DMI also called SMBIOS. The tool is exporting a table contents.

On this platform we are not on x86_64 but aarch64:

[email protected]:~$ uname -m
aarch64
NVIDIA Jetson nano module
NVIDIA Jetson nano module

dmidecode can be used to detect server type, but not for all platforms.

☑ lshw

lshw can help to find the server model and product names we can see the product jetson-nano:

[email protected]:~$ sudo lshw -C system
neuralux.lan.net.com              
    description: Computer
    product: jetson-nano
    serial: 01010101010101010
    width: 64 bits
    capabilities: smp cp15_barrier setend swp

To get all information as capabilities or usbhost, you need to run lshw as root:

[email protected]:~$ lshw  | wc -l
WARNING: you should run this program as super-user.
WARNING: output may be incomplete or inaccurate, you should run this program as super-user.
111

[email protected]:~$ sudo lshw  | wc -l
147                         

☑ hwinfo

hwinfo can help to find the vendor type.

[email protected]:~$ sudo hwinfo | grep vendor
    vendor = 0x10de
    subvendor = 0x10de
    vendor = 0x10ec
    subvendor = 0x10ec

0x10de is the NVIDIA vendor type, NVIDIA is building may type of servers, but it’s giving information on the server vendor.

☒ inxi

inxi cannot find the server model or product:

[email protected]:~$ inxi 
CPU~Quad core ARMv8 rev 1 (v8l) (-MCP-) speed~518 MHz Kernel~4.9.140-tegra aarch64 Up~19 min Mem~596.5/3964.6MB HDD~NA(-) Procs~234 Client~Shell inxi~2.3.56  

☑ tegrastats

tegrastats is a tool provided by NVIDIA for the Jetson platform. The tegrastats reports memory usage and processor usage for Jetson-based devices, so when you get some data, it means that you are on one Jetson:
