How to add vi into the Linux build

I have Linux boot OK on the board from my image.
How I can have utilities such as vi in my Linux build?

Thanks!

if you are using the ubuntu image from the lx2160a_build then you can use apt to install any additional software.

When and where should I use apt:

  1. On lx2160A board after the Linux boot or 2. On the development Linux PC before build?
    Thanks!

After you have booted and installed Ubuntu on the LX2160a. If you want to add packages to the Ubuntu Image during the build process then you will need to modify the runme.sh script, lx2160a_build/runme.sh at master · SolidRun/lx2160a_build · GitHub
