Well, we never know :-) I mean, we're always open to fixes to make it work as long as they don't impact other platforms. > the target seems to be present in the > Makefiles and I'd love to be able to use it.

The info I'm finding on the net suggest that symbols must be resolved at link time, which is the case here. So maybe it's just a matter of definition. I can suggest a few things to try in include/common/ist.h : - replace "__weak__" with "weak" just in case it's different there (I don't even know why I marked it "__weak__", probably just by mimetism with "__attribute__" and because it worked - add "#pragma weak ist_lc" and "#pragma weak ist_uc" in ist.h, before the definitions - add "extern const unsigned char ist_lc;" and "extern const unsigned char ist_uc;" before the definitions In case one of them is enough to work, we can merge them.
