<p><b>New page</b></p><div>So the issue with the Blue/Yellow appears to be when the serial driver loads, it for some reason resets GPIO 7 & 8. So the setting that the vendor put in /boot/config.txt gets overridden.<br />
<br />
So, I put the following mini startup script in to run on boot. Script location-name: /etc/systemd/system/fixgpio.service Script contents below:<br />
<br />
[Unit] Description=fix gpio for screen<br />
<br />
[Service] Type=simple ExecStart=/usr/bin/raspi-gpio set 7-8 a2<br />
<br />
[Install] WantedBy=multi-user.target<br />
<br />
Then run service fixgpio enable and reboot.<br />
