I also though about it and the previous post. But I also saw PA0 needs to be high for SAM-BA, and the the pull-up is enabled at reset. That is why I was wondering. Also we had no problem with the devboard from olimex (with no additional pull-up). Maybe I'm doing something wrong. There is a newer version of the datasheet (28-Jul-11), but the information about that did not change. Thanks, Kevin
