Hi Dnyaneshwar_3D,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

It seems a 3rd-party tool to use SPI interface with RC522 module to read the UID of NFC tag.
Do you verify SPI loopback test working before using this tool?

I am using devkit for Jetson Nano Developer kit .
how to verify SPI loopback test working or not ?

for jetpack version i have attached one image can you tell which jetpack it is ?

It seems you are using the devkit with R32.7.1.
We would suggest updating to the latest R32.7.4 (JP4.6.4).

and refer to the following thread to enable/verify SPI loopback test.
Jetson Nano SPI Bus Not Working - #10 by KevinFFF

yes i am refering that only .

Thank you

about updating to latest R32.7.4(JP4.6.4)
How to upgrade to it ?

any references

For the devkit, you can just use SDK Manager to flash it with R32.7.4.

showing this version .

but after previous command it still showing :
R32 (release), REVISION: 7.1

okay, it seems you’ve updated to the latest R32.7.4 release (come with Jetpack 4.6.4)
