we use imx8mp product correctly displaying a custom kernel boot logo as logo.bmp on nxp android 11 The boot logo image initially displays fine, but right before the "android" boot animation begins the boot logo color palette changes for a brief moment(red colors change to blue for about a second)., But, then the android boot animation runs correctly and the android Launcher3 home screen then displays correctly. It is just this odd transition between the kernel boot logo and the android boot animation. i tried this method but not used
