Hi Sir

We followed the suggestion to implement u-boot splash and it worked.

And we found the logo must be bmp 565 format.

We found the color is BGR instead of RGB.

Do you know how to modify the register to show the logo in RGB

Hi SIr

1. We used latest SDK for development

2. It is display output

3. We found the discussion about this issue in below link
e2e.ti.com/.../2289777
It needs to add blue-and-red-wiring = "crossed"; in dts.
And u-boot seems it cannot work and has not this setting after grep all u-boot code.

please advise

It may be necessary to apply the linux patches associated with the blue-and-red-wiring, yet to be implemented in the sdk, into your u-boot source code.
