Console output starts before the environment is looked at, so this shouldn't be the root cause. I didn't understand where you erased the file. Did you erase it in your build, so in the default environment, or did you erase it during runtime from the saved environment? For the former it could be that the object positions in the binary moved to some unlucky place. FOr the latter it could be that the environment partition overlaps with the barebox partition so that a saveenv accidently overwrites parts of the barebox image.
