Is it possible build a OpenSTLinux related stuff (FSBL, SSBL, U-BOOT, Linux Kernel, etc.,...) without building a specific image? I would like to run Debian Stretch 9 as rootfs. All libraries will be installed later as .deb packages.

Hello gianlucarenzi,

yes it is possible to build separate components provided that:

• you have set your build environment (source layers/meta-st/scripts/envsetup.sh)
• you have identified the related recipes corresponding to what you want to build. (e.g bitbake linux-stm32mp)

You can refer to wiki.st.com to get information on bitbake commands that will help you identify such recipes.

Regarding debian, there are solutions to build a debian distribution that you can use within yocto, such as the meta-debian layer. Though ST doesn't support the debian distribution, you can also refer to wiki.st.com to see how to add a layer
