Hello, I am using Jetson nano a02 (4gb) latest version of jetpack is installed.  
I want to enable spi pins to connect rfid module to jetson. There is a program called 40 pin extention. It works with jetson-io.py file.

When I run it from the terminal, it does not respond. When I run it with uxterminal, it appears for less than half a second and turns off.

Hi sentrycoder.dev0,

Could you help to run the following command on your board and share the result here?

```auto
$ cat /etc/nv_tegra_release
$ cat /etc/nv_boot_control.conf

```

Is there any serial console log output when you run Jetson-IO?  
Do you run it with `sudo`?

```auto
$ sudo /opt/nvidia/jetson-io/jetson-io.py

```

It seems the duplicate topic as [Jetson 40 pin expansion header configuration - Jetson & Embedded Systems / Jetson Nano - NVIDIA Developer Forums](https://forums.developer.nvidia.com/t/jetson-40-pin-expansion-header-configuration/261483/3), let’s discuss there.
