Hi @sicScar1
The <default_bootloader> is the bootloader built without the falcon patches. To generate the default bootloader, remove the meta-imx-fastboot layer from BBLAYERS.
The <falcon_mode_bootloader> is the bootloader that includes the falcon patches. To generate the falcon mode bootloader, add the meta-imx-fastboot layer to BBLAYERS.
If the meta-imx-fastboot layer is present, only the <falcon_mode_bootloader> is generated. If the meta-imx-fastboot layer is removed, only the <default_bootloader> is generated.
Indeed, there should be no major difference between the patches for EVK and Verdin.
