Unfortunately not picking a provider for "virtual/bootloader" will result in bitbake attempting to build all providers (since EXTRA_IMAGEDEPENDS is depending on virtual/bootloader), as bitbake has no idea which one is desired (and they are all compatible). -- NOTE: multiple providers are available for virtual/bootloader (u-boot-xlnx, u-boot-xlnx-dev, u-boot) NOTE: consider defining a PREFERRED_PROVIDER entry to match virtual/bootloader ... ERROR: Multiple .bb files are due to be built which each provide virtual/bootloader ... <various failures due to overlapping files/etc.> -- Also note, meta-petalinux or other layers should already be able to override this default (by setting with ??=) either in a distro conf or in a machine conf e.g. zynq-generic (for meta-petalinux).
