L4T 24.2 boot splash

Hi All

Please share your experience to setup a boot splash graphic screen instead of console messages.

Thank you,
Alex

Hi Alex,

Which display are you trying to setup splash graphic? Is it HDMI-out or a panel?

Hi WayneWWW,

Thank you for your for your quick response.

We are talking about DSI-0 display, that becomes tty0 for boot process since specified in DT.

Best regards,
Alex

Alex,
Sorry for late reply. Boot splash is not supported by u-boot on L4T TX1. However, you can reference to the source code.
Please follow the document.
https://developer.nvidia.com/embedded/dlc/l4t-documentation-24-2-1

The splash related codes can be found in u-boot/common/splash*

Hi WayneWWW,

Thank you for the reference.

But where could I find the doc l4t_uboot_guide.html you mentioned?
It seems the link is local one.

Best regards,
Alex

Hi Alex,

Sorry for the error link. Please take a look at the previous post.

Hi WaneWWW,

Thank you.

As far I understand the problem is a DSI panel driver absence in u-boot src code…
