- Okay good to hear.
- HW 08:05 PM Software Development: RE: AM62A: Getting the Splash Screen to Appear Earlier
- The changes work great, got it working with our display no problem!
I see what you mean with the scrambled splashscreen, I was going to start following the documentation for handing the frame buffer off to Linux and see what happens w... - JC 04:06 PM Software Development: RE: Getting the Splash Screen to Appear Earlier

- I have made some good progress on this today. I've got to do some cleanup but i'll try to push a test branch for you to test. Note i'm using our devkit with the hdmi output but I believe switching to your touchscreen should be straight...

- Note one thing I ran into is the ti-dss driver in 2025 u-boot, doesn't currently support switching to video port 1 (where the 62a connected the VOUT pins). There is a upstream patch to add this support so I'm testing if it can be backpo...

- I am also attaching the Linux dts, I know the bindings are a little different for the u-boot drivers so I tried to match as closely as possible for the panel and backlight nodes

- Can you share the changes you've made so far as a patch/diff?
- HW 06:57 PM Software Development: RE: Getting the Splash Screen to Appear Earlier
- I was able to create nodes in the u-boot device tree for my panel, pwm-backlight, and the video driver (dss).
In drivers/video/tidss/tidss_drv.c added the compatible line for the am62a7 so the tidss driver can bind properly

- Just for some clarification, the documentation says to modify board/ti/am62ax/evm.c to change the SPL init function and enable video even in custom boards based on the am62ax SoC. Is all board configuration contained within the board/cl ...

- There was some change I think around TI's SDK 9, that greatly delayed the /dev/fb0 creation. I didn't dig into it at the time, but I agree its not ideal.
I do think that getting the u-boot splash screen support working would make the... - Good morning,
I am finding that the psplash screen comes up very late while the kernel is initializing to the point where it sometimes does not appear because it is started as the kernel boot is completed.
After running systemd-ana...
