^^^^^
- The AVR32DEV1 reset button is not useful for restarting the program. It
- seems that, after the reset, the RTC is left is a bad state and is constantly
- busy (this might be the fault of the bootloader???). There does not seem
- to be any way around this except for power cycling the board.
+ I don't trust the reset button -- if you reset and something weird happens,
+ try a full power cycle.

+Make Tip
+^^^^^^^^
+
+ Because this build uses a native Windows toolchain and the native Windows
+ does not understand Cygwin/POSIX paths, the NuttX make sysem does something
+ weird: It copies the configuration directories instead of simply linking
+ to them (it could, perhaps, use the NTFS mklink command, but it doesn't).
+
+ A consequence of this is that you can easily get confused and get editting
+ a file in one of the linked directories, re-build, and not see your changes.
+ To work around this annoying behavior, I also do the following when I make:
+
+ make clean_context all <-- Remove and re-copy all of the directories, then make all
+ doisp.sh <-- Load the code onto the board.
