how to add boot animation to tk1

how to add boot animation to tk1

Don’t know…but I would guess that if you can do this it would be to add an animated image under plymouth (plymouth handles splash screens, though it does more than this):

The steps for doing this are likely the same on a Jetson versus other Ubuntu.

Thank you very much linuxdev, PLymouth can handle boot animation.

And Now,
Is plymouth can handle charging animation? (I am working on battery powered system)

or do you know any other ways to add/setup charging animation.

I do not know which image types plymouth supports, but perhaps it can handle an animated GIF?

It looks like there are a number of alternate splash screen schemes. Under R28.1 Usplash might apply:

I have not tried to set this up, so I don’t know how easy/difficult this would be.
