Hi Stefan,

I agree that it is odd that a recipe copies a file, in this case the
bl31 bootloader image, from the deploy area to the recipe area. This
bootloader binary is created by the imx-atf recipe. imx-atf is listed as
a dependency for imx-boot which is the recipe that is failing in your
build. Therefore I would expect imx-atf to run before imx-boot. However,
a recipe's do_compile task does not depend on another recipe's do_deploy
task but on the other recipe's do_install task. What likely happened is
that imx-boot do_compile was started after imx-atf do_install completed
but before imx-atf do_deploy has completed. For imx-boot to work
correctly it should copy the files from imx-atf's staging area rather
than the deploy directory.

I suggest that you try to run imx-atf alone to see if it builds and if
the bl31 image is built and placed into the deploy directory. And then
run your build again.
