        <b>STATUS:</b>
-         A basic OS test configuration is in place, but the board does not boot.
+         Two verified configurations are available:
-         It looks like I will need an ICD3 in order to debug the code (PICkit3
+         (1) The basic OS test configuration that verfies the correctnexx port of Nuttx, and (2) an extensive <a href="NuttShell.html">NuttShell (NSH)</a> configuration.
-         doesn't work for debugging with this board).  This effort is temporarily stalled.
+         The NSH configuration includes:
+         (1) Full network support,
+         (2) Verified SPI driver,
+         (3) SPI-based SD Card support,
+         (4) USB device support (including configuration options for the USB mass storage device and the CDC/ACM serial class), and
+         (4) Support for the MIO873QT2 LCD on the PIC32MX7 MMB.
