Apparently your forgot to put the .elf files in the X/cdk/boot folder. In that case the build completes (this has been the case for many years now) but flash.sh fails as flashing an image without .elf files is useless. The Archive folder was probably placed outside the build environment and in the users' home folder because if you have more than one build environment (I usually do) they all share the same Archive folder. If you want it inside the build environment you have to modify configure.ac in the X/cdk folder. Currently a test build for TVHE on the HS8200 is running to test if everything is as intended.
