<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. <br />
Script location-name:<br />
/etc/systemd/system/fixgpio.service <br />
Script contents below:<br />
<br />
[Unit]<br />
Description=fix gpio for screen<br />
<br />
[Service]<br />
Type=simple<br />
ExecStart=/usr/bin/raspi-gpio set 7-8 a2<br />
<br />
[Install]<br />
WantedBy=multi-user.target<br />
<br />
Then run service fixgpio enable and reboot. <br />
