Two things that aren't obvious from your code snippet: a. Are the base addresses the same for both code ? Or are you using different one? Have you check the manual to decide in which address (range) you should map? b. How do you know which one is valid and which one is not? To me: both looks "good", depending on whether the mapping address is considered valid or not. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
