I wonder if the other Cortex variants (A8, A9, R4, M1) should be
considered for porting from the beginning. My focus is clearly on the
M3, but if anyone is willing to work on the other variants this should
be considered now.
Have you seen any documents which compares/contrasts the different
Cortex variants. Before answering your question it is necessary to
know how similar/different the different variants are.
No I haven't really. All I know is that the variants all have very
different application profiles. A series being mostly for complex OS and
applications, R series for more complex embedded applications and the M
series for deeply embedded applications. A & R also support normal Thumb
and ARM instructions. Perhaps someone else can give some insight?
