how display logo on boot ?

[okpapt]

Hello,

I have installed armbian on a tv box.
I think my question is not specific a kernel, a soc, a cpu.

Now and before new modifications, I will make several backup of the eMMC.
But armbian-ddbr works only from the usb key.

Up to the login (different user and password on usb and on box) at the beginning, I cannot know if I'm booting from the TV box or the USB key and it's a big waste of time.

In order to quickly view the difference, is it possible to display a logo or splash screen when I boot from usb or box ?

Sorry for my bad english, have a good day.
