Ack, sorry. For posterity sake:

$ newt run bleuart 0.1.0

'newt debug *' works with the elf, I forgot about the version requirement with 'run' to also generate the updated .img file, thanks.

Was the build process recently updated to output .elf instead of .img?

I'm on 1.0.0 for everything (tools and core repo).

On OS X with GCC 5.4.1 (the latest release from ARM) I get:
