STATUS/ISSUES
=============
1. See configs/samd20-xplained/README.txt. This port derives from the
SAMD20 Xplained board board and all issues there should apply.
2. 2015-06-28: As of this writing, no testing has been performed. The
board is on order and testing will begin when I have the board in hand.
3. 2015-07-03: Board received. Does not work on initial tests. There
is, apparently, some problem in the clocking setup.
2. 2015-07-06: The basic NSH configuration is working properly, but
not at 115200 baud which is the default BAUD selection in the
configurations. It is necessary to drop the BAUD in the
configuration.
I suspect that this is an issue on my board and due to running the
system on uncalibrated OSC8M. My bet is that the issue would not
exist on many boards or if OSC8M were calibrated or if a more precise
clock source were used (like XOSC32K).
... After more experimentation, I am not sure this conclusion is
correct or not. Perhaps the board just comes up with a bad clocking
configuration at times????
