Build your own image

LinuxOnARM for Wandboard describes the steps in great detail.  Building your own image has the advantage that you can set your own kernel options (if you know what you're doing).  I used Linux kernel v5.6.x (Stable) with Ubuntu 20.04 LTS.

Before you do this, install the following packages on your build computer:

sudo apt install bison flex lzma libmpc-dev u-boot-tools libncurses5-dev:amd64 libssl-dev:amd64

Login

ubuntu / temppwd

WiFi

Don't copy the files yet as shown in the instruction.  See WiFi project log for more info.

Setup microSD card

Before installing the files onto the SD-card, unmount the existing partitions first.

Install Kernel and Root File System

The kernel version can be found in the file kernel_version in the linux kernel.
