Bug or other?

[QiaoTuCodes]

We can't useing the Native code emitter & Viper code emitter on canmv boards! why?

a sample here:

@micropython.viper
def foo(self, arg: int) -> int:
    # code

@micropython.native
def foo(self, arg: int) -> int:
    # code

We are test out any mpy-boards it's support this method in all micropython versions of anyway. but seem can not to be useing on the K210 chips? i don't know why? can you explain that? Thanks anyway!
