self.elf_file = ELFFile(in_stream, sys.stdout)

Use http://elm-chan.org/fsw/ff/doc/findfirst.html to find all .bin images. Then loop through all .bin images and

• Match the hardware version in each image.

• Search for the *.bin image with the "newest/highest software version" File name doesn't matter except for the file-ending.

• Compare software version from newest *.bin file to the currently running version. Flash if the uSD image contains a different version.

• No role-back protection and no Signature (authenticity) checking right know.
