Title: Splash Screens on the A64...U-Boot, Plymouth?
Post by: afancher on February 19, 2021, 06:16:35 AM
Hi, has anyone had any luck or experience with configuring a splash screen on a current or past Olimex Debian release on the Olinuxino-A64?

I am exploring the options of enabling it in U-Boot at the prompt, however bitmap support seems not to be enabled in the currently distributed U-boot configuration and I'm assuming requires a rebuilt u-boot binary.  I have tried adding the lines
setenv splashsource mmc_fs
setenv splashfile /boot/logo.bmp
setenv splashsource mmc_fs
to no avail in both the boot.cmd/scr and uEnv.txt files.  Additionally, I am unable to enter save these commands at the u-boot command prompt as the "savenv" command returns a response of  "Saving Environment to EXT4... Unsupported feature metadata_csum found, not writing. Unable to write "/uboot.env" from mmc0:1, Failed" (which is a side note that applies in general to writing any environment variables at the current U-Boot prompt)

I have also looked into using Plymouth as it seems to be a popular option for splash screens, and I did in fact see that Plymouth is initialized already by the current OS release.  I have installed a theme and it doesn't seem to be working (no theme displayed) despite rewriting the initial ramdisk after changing the theme as advised.

Any ideas?

Thanks!

Membring same problem on gentoo
1) no easy ways
2) shut up u-boot by removing from sorce every output
3) may be needed do the same on systemd
4) https://www.kernel.org/doc/html/latest/fb/fbcon.html

that way https://developer.toradex.com/knowledge-base/splash-screen-linux
still have output of u-boot and some systemd messages

hmmmm...perhaps a tweak that could be made to the next release Lub might be able to put in the developer's ears about? ;)

Any chance of this board ever having splash screen support implemented?
