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

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