Bootloader to kerel in seamless usecase

[rd1]

In kernel dc, there are some config for seamless usecase from bootloaderto kernel.
How to close the seamless config, because we used bridge ,it didn’t be seamless .
I change the interface ‘tegra_is_bl_display_initialized’ returen false, is it ok?

Hi, WayneWWW,
you mean it would cause a blanked screen after logo shows up, on Xaiver NX devkit if directly return “false”.

A “short” blanked screen. The desktop GUI would still come out after the blank.

ok,thanks!
And we had a case: it will had a red or blue or gren or other color screen after logo shows up. So we suspect maybe seamless config cased.
