Once your UP@ has been updated, you will need to provide permission to the `upsquared` user to access the GPIO or I2C subsystems on the board.
Once your UP2 has been updated, you will need to provide permission to the `upsquared` user to access the GPIO or I2C subsystems on the board.
### Configuring GPIO on UP2 board
To access the GPIO subsystem, you will need to create a new group, add your user to the group, and then add a UDEV rule.
First add a new UDEV rule to the UP2 board. Add the following text as a new UDEV rule named `/etc/udev/rules.d/99-gpio.rules`:
First, run the following commands on the board itself:
```
sudo groupadd gpio
sudo adduser upsquared gpio
```
Now, add a new UDEV rule to the UP2 board. Add the following text as a new UDEV rule named `/etc/udev/rules.d/99-gpio.rules`:
