Hi all,I want to display a custom logo in the splash screen for a specified amount of time (SeaBIOS as payload). How do I configure the logo and give a timeout when building coreboot? Any pointers will be really helpful.
Logo: https://www.seabios.org/Runtime_config#Bootsplash_images (bootsplash.jpg)
You may add the custom logo to the CBFS by specifying the path to logo file during coreboot build in menuconfig General Setup -> Add a bootsplash image SeaBIOS is quite picky regarding the format of the JPEG and BMP. Be sure to use some legacy screen resolution, the logo file must also exactly match the screen resolution. Here is a blog from Purism where some struggles with JPEG format and SeaBIOS are discussed: https://puri.sm/posts/librem-13-coreboot-report-february-25th-2017/
Specified amount of time: https://www.seabios.org/Runtime_config#Other_Configuration_items (etc/boot-menu-wait)
The timeout can be added using cbfstool after the build is finished:cbfstool coreboot.rom add-int -r COREBOOT -n etc/boot-menu-wait -i <timeout_value>
If you have vboot with multiple CBFSes then you would also need to run:cbfstool coreboot.rom add-int -r FW_MAIN_A -n etc/boot-menu-wait -i <timeout_value> cbfstool coreboot.rom add-int -r FW_MAIN_B -n etc/boot-menu-wait -i <timeout_value>
