Hosyond 3.5" tft display shows software rev 4.1.0.3 then goes blank unless touch plugin rev 3.6.0 is uninstalled. When uninstall of plugin starts the display shows the login screen that you see normally from HDMI port. the Volumio OS is installed on a RPI 3B+. I have tried many diffenent instructions to install the display but the instructions below are the ones that are currently loaded on a fresh image.
- Install Volumio as usual by buring image to micro SD . I will not go through detail here as you can see it from Volumio Official Site.
- Turn on raspberry PI and configure Wireless if you use it.
- Open volumio.local in browser and install Plugin Touch Display and Enable Plugin.
To configure volumio , we will use SSH and remote to volumio. We have to enable SSH by browsing URL http://volumio.local/dev and click - Enable SSH .
connect to volumio.local user name :volumio@volumio.local and password :volumio - When login to volumio you will see the prompt volumio@volumio:$ and current directory is /home/volumio
- Enter this command line by line with Enter.
