 ^^^^^^^^^^^^^^^^^^^^^^^^
 
-If you use any version of ZDS-II other than 4.10.1 or if you install ZDS-II
-at any location other than the default location, you will have to modify
-two files:  (1) configs/z8encore000zco/*/setenv.sh and (2)
-configs/z8encore000zco/*/Make.defs.
+4.10.1
+  The ZDS-II version 4.10.2 will not compile NuttX.  It reports "internal
+  errors" on one of the files, mm/mm_initialize.c.  Below is a simple work-
+  around.  With this work-around in place, NuttX builds successfully with
+  the 4.10.1 compiler.
