Thank you very much for the VIB. I would like to turn the power on to my rPi4 fan. I installed your VIB successfully but when I try and run gpio_util.py, I get this error. TIA.

Hi Dennis,

Was the RPi rebooted after installing the VIB? You'll need to do that for the driver to load and create a character device file at /dev/vmgfx32. I've added that to the readme now.

If, after rebooting, you still can't use the util script, please run the following command and paste the output into this thread:

zcat /var/log/boot.gz | fgrep gpio

Posting here as a reminder to myself to review the build script.

I did not reboot. My apologies. All good and closing the issue. Thank you.
