Troubleshooting
There is a number of things that can prevent the PINE A64(+) board from booting up properly. The most common culprits of a failed boot are (to find out more click here):
Subpar or counterfeit microSD card
Subpar Power Supply
High resistance (thin) or a very long microUSB cable
Failed imaging of the microSD card (refer to the respective โimaging microSD card section)
Make sure to have the newest version of the OS image your are running. On Linux, you can update the kernel and uboot using scripts located in the following directory: /usr/local/sbin
To navigate to the directory type (in terminal): cd /usr/local/sbin
You list all the available scripts by typing (in terminal): ls
To run the script required update script run the following command: sudo ./update_script.sh (substitute the relevant update script for update_script)
Supported Screen Resolutions
The pine supports a number of video resolutions under Linux, however RemixOS and Android images currently only support 720p and 1080p. Linux supports a wider range of resolutions (see all resolutions supported on Linux here). If the native resolution of your monitor or TV is not compatible with the PINE A64(+) then you will be unable to get a video to work with your screen.
Troubleshooting Step by Step
Follow these steps to determine the cause of your problem:
Check your PSU and barrel cable ratings
Download and image a base image of Linux
Plug in Power and Ethernet into your Board
Watch Ethernet port LED activity
Check your router for SOPINE IP
Attempt to ssh into the SOPINE from your computer
