I don't consider it a big problem (just a bit sad) if ELDK 4.2 cannot
be used for building these. However, I think it is not acceptable
tobuild known-to-be-broken images. If the tool chain is too old, this
shall result in a clear error message and abort of the build.
Why is thumb mode needed for these boards? Just because of image
size?
Best regards,
Wolfgang Denk
