Hi Richard, Ah yes, so perhaps we would have a bare metal tool chain with the or32-elf-* name and pass -mor32 to it to specify the 32-bit or1k machine? I would hope, though, there's ways of building the tool chain where we can hard code such options, but is that more in the realm of the gcc tool chain config?
