Hello,

Unfortunately, the board that you are using is not still supported since is not officially released yet. However, keeping the booting logo in the newest Android released is no supported. We do have some patches for old Linux and Android releases. You can look at them and try to implement the patches on your own.

Hello

This patch must use IPU. IPU configuration is not seen in IMX8QM, only ISI.

Can this patch be used?

Thanks

Unfortunately, not as it is. For the same reason that the i.MX8QM does not have an IPU. However, this is the most accurate approach that we have for the moment and according to some previous comments from the developer of the patch, there are no recent future plans to port it on the i.MX8 family chip processors. You can take the patches and use them as a reference. Or you could go with professional service support. They could help you in the developing of a patch that could support the modification of the booting logo.

I apologize for the inconvenient this may give you.

Hello @Truong Huy

How did you get the bmp display command to work. Did you apply any code patches or change any source code in uboot?

I am not able to get bmp display command to work.

Could you please send me some details as to what you did to get it to display. It would be greatly appreciated.

Use setenv command in uboot ："setenv panel IT6263", this work for me to use bmp display command.
