Change Start logo on Android

Hi everyone, i would like to know how i can change the "FriendlyARM" Logo
that appears at the start of my Nano PC T2.
I'm using android and need to change this
Best Regards

Change the file boot/logo.bmp.
IT is related *ONLY* to initial scrennshot.

if you want to modify also the "videoclip", go to system/media and
delete/modify/replace the several images inside the file
"bootanimation.zip"

Thank you very much!
