I'm developing an application in Qt on imx6Solox. I created the image with Wayland and its kernel version is 18.104.22.168.0. I'm wondering how to change the Nxp logo while is shown the system is booting. Also, can I upload a video in splash screen? If yes, how? Finally, I want to make my own distro or OS for imx, how can I make this? Could you suggest me a book or an article to make these?
