i want to connect RFID MFRC522 with Nvidia jetson nano. However, the Nvidia Jetson Nano cannot read the ID on the RFID tag. I have followed various tutorials but still can’t. when I use arduino, my RFID MFRC522 works, this proves that my RFID MFRC522 is fine. Please help and direct, to use RFID MFRC522 with NVIDIA Jetson nano
Hi jayasaputra2412,
Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?
How do you connect the MFRC522 module with Jetson Nano?
(i.e. which interface are you using? I2C or UART or SPI?)
Have you ported the related custom driver for your RFID module?
I am using nvidia jetson nano dev kit, i am using spi interface. What kind of porting?
I followed the method in this link

Are you using Jetson Nano devkit with eMMC or SD module?
You might need the custom driver for your RFID module.
If you just refer to the instruction from the link you shared, jetson-io would just configure the correct pinmux for SPI interface and use default spidev driver.
Could you run that python script(Jetson-MFRC522 library) for your module?
Is there any error message in dmesg?
i am using jetson nano dev kit with SD. what kind of driver is required for the RFID module?
I Can run the python script (Jetson-MFRC522 library) and there are no errors. it’s just that the RFID tag cannot be read
I’m not sure if there’s any custom driver needed for your RFID module.
We don’t have your RFID module so that we could not verify it locally.
Please request your RFID vendor for the usage.
Have you verified the SPI loopback test on the devkit before connecting RFID module?
Have you verified the SPI loopback test in the devkit before connecting the RFID module?
what is this? how to do it?
Please refer to the following thread for SPI loopback test.
