4.3.6.2.6. Verifying FPGA Device Drivers

The device drivers should be loaded when the HPS boots. Verify that the device drivers are initialized by checking that uio files are listed in /sys/class/uio by running the following command:
ls /sys/class/uio
The command should show output similar to the following example:
uio0 uio1 uio2
If the drivers are not listed, refresh the modules by running the following command before checking again that the drivers are loaded:
uio-devices restart
