we have configured a splash screen for u-boot on Apalis imx8 following the guide (Splash Screen on U-Boot | Toradex Developer Center) but no image is displayed.
Our panel uses dual lvds with DE mode. How can we set mode and timings for our panel in u-boot?
Hi @ floji
I’m curious about your progress ,
I have a similar ( a bit ) system and a similar problem (colibri imx8x+ lvds)
I have the impression that the information on the toradex site is for old systems
, the descriptions do not work on imx8x (in my opinion)
When I see on TORADEX youtuber channel u-boot logo on colibri IMX8X , I will believe it !
I see some people asking about it, but I don’t see any solutions
since splash screen support for kernel has been dropped with BSP 6 we are now running out of options. Running a user space splash application takes way too long.
Is there any chance we might get U-Boot splash support on iMX8 or at least get the kernel splash screen back? Other SOM manufacturers do support splash screens for U-Boot and kernel.
the earlier a splash screen is shown the better. I think 1.5 (2s max) would be good. Customers start to get nervous if a blank screen is shown longer.
Our current unit (iMX6) shows boot loader splash screen almost instantly and then blends over to kernel splash screen. Loading our application takes a few seconds so early feedback is required.
sorry for the late reply.
I’ve installed psplash using initramfs. Currently it takes around 6,5s for the splash screen to appear.
I tried all the “low-hanging fruit” from the links you provided. There are a few things left that I can do (e.g. further reducing kernel size) but I doubt that I can save more than additional 0,5-1,0s.
Could you please tell us more about this? Which exact strategy was used here? Also, if possible share the version of software used (e.g. kernel - upstream or downstream? -, u-boot, psplash). Also, how the handover was implemented?
If you prefer, we can make this thread non-public, so you can share more details.
