+Serial Console
+==============
+
+  Pin Availability
+  ----------------
+  The EFM32G890F128 support the following options for serial output.  NOTE
+  (1) that not all of these pins are available for use as a serial console,
+  however.  And (2) not all pins made available by the board.

+   LEUART1 is available on through an RS232 driver on DB-9 connector.
+   Unfortunately, there is no LEUART serial driver available in NuttX as of
+   this writing.
+
+   Default Serial Console
+   ----------------------
+   UART0 is configured as the default serial console at 115200 8N1
+   on pins PE0 and PE1.
+
+Configurations
+==============
+  Each EFM32G880F128-STK configuration is maintained in a sub-director
+  and can be selected as follow:
+
+    cd tools
+    ./configure.sh olimex-efm32g880f128-stk/<subdir>
+    cd -
+    . ./setenv.sh
+
+  If this is a Windows native build, then configure.bat should be used
+  instead of configure.sh:
+
+    configure.bat olimex-efm32g880f128-stk\<subdir>
+
+  Where <subdir> is one of the following:
+
+  nsh:
+  ---
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables the serial interfaces on UART0.  Support for
+    builtin applications is enabled, but in the base configuration no
+    builtin applications are selected (see NOTES below).
+
+    NOTES:
+
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configuration using that tool, you should:
+
+       a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+          and misc/tools/
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. By default, this configuration uses the CodeSourcery toolchain
+       for Windows and builds under Cygwin (or probably MSYS).  That
+       can easily be reconfigured, of course.
+
+       CONFIG_HOST_WINDOWS=y                   : Builds under Windows
+       CONFIG_WINDOWS_CYGWIN=y                 : Using Cygwin
+       CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
