Hi,

I have tested it on my macbook (brought last year) and it works
without issue. I don't know about later modals, but they shouldn't be
too different. Anyway, this looks like a memory problem, perhaps you
can define some global variable in startup.S and main.c, and test if
it halts when writing to it from within the same file.

BTW, is refit working ok ?
