-        Read-only data must reside in RAM.  
+        With older GCC compilers (at least up to 4.3.3), read-only data must reside in RAM.  
         In code generated by GCC, all data references are indexed by the PIC<sup>2</sup> base register (that is usually R10 or <i>sl</i> for the ARM processors).
         The includes read-only data (<code>.rodata</code>).
         Embedded firmware developers normally like to keep <code>.rodata</code> in FLASH with the code sections.
         But because all data is referenced with the PIC base register, all of that data must lie in RAM.
         A NXFLAT change to work around this is under investigation<sup>3</sup>.

   Description: Windows build issue.  Some of the configurations that use NXFLAT have
                the linker script specified like this:
 
-               NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat.ld -no-check-sections
+               NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections
 
                That will not work for windows-based tools because they require Windows
                style paths.  The solution is to do something like this:
 
                if ($(WINTOOL)y)
-                 NXFLATLDSCRIPT=${cygpath -w $(TOPDIR)/binfmt/libnxflat/gnu-nxflat.ld}

+NuttX OABI "buildroot" Toolchain
+================================
+
+  The older, OABI buildroot toolchain is also available.  To use the OABI
+  toolchain:
+
+  1. When building the buildroot toolchain, either (1) modify the cortexm3-eabi-defconfig-4.6.3
+     configuration to use EABI (using 'make menuconfig'), or (2) use an exising OABI
+     configuration such as cortexm3-defconfig-4.3.3

+NXFLAT Toolchain
+================
+
+  If you are *not* using the NuttX buildroot toolchain and you want to use
+  the NXFLAT tools, then you will still have to build a portion of the buildroot
+  tools -- just the NXFLAT tools.  The buildroot with the NXFLAT tools can
+  be downloaded from the NuttX SourceForge download site
+  (https://sourceforge.net/projects/nuttx/files/).
+ 
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lpcxpresso-lpc1768/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-nxflat .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly builtNXFLAT binaries.
