Building SD Card Image Components

Hello All,

When I build my application bitbake myapp I get a .wic.bz2 file. I can then flash this onto an SD card. This image contains UBoot, Kernel and RootFS.

Is there a way to tell yocto to separate these? Can I build only UBoot? Or only te Kernel?

Did you look in the folder “build/deploy/images/…” ?
In my opinion everything is there

Or second option build kernel/u-boot from source out of bitbake
