+       You can debug the all RAM version using ZDS-II as follows:
+
+       a. Connect to the debugger,
+       b. Load the nuttx.lod file
+       c. Set the PC to 0x040000
+       d. Single step a few times to make sure things look good, then

+
+    5. Optimizations:
 
        - The stack sizes have not been tuned and, hence, are probably too
          large.
-       - Currently the code runs out of FLASH.  Running out of the zero-
-         wait-state RAM would be much faster!
