+= Overview =
+
+
+This is the cheapest evaluation board the Stellaris LM4F CPU family. '''NOTE: Please note that after the release of the LM4F Stellaris family, TI went ahead and rebranded whole Stellaris LM4F line to Tiva C Series or Tiva C TM4C family. See below for a link to table listing corresponding part of LM4F and TM4C families'''
+= Features =
+
+ *  Stellaris LM4F120H5QR microcontroller
+ *  USB micro-B connector for USB device
+ *  RGB user LED
+ *  Two user switches (application/wake)
+ *  Available I/O brought out to headers on a 0.1-in (2.54-mm) grid
+ *  On-board Stellaris ICDI
+ *  Switch-selectable power sources:
+  *  ICDI
+  *  USB device
+ *  Reset switch
+ *  Preloaded RGB quickstart application
+ *  Supported by StellarisWare software including the USB library and the peripheral driver library
+ *  Stellaris LM4F120 LaunchPad BoosterPack XL Interface, which features stackable headers to expand
+the capabilities of the Stellaris LaunchPad development platform
+= Documentations =
+
+ *  Stellaris® LM4F120 LaunchPad Evaluation Kit User's Manual (Rev. B) [http://www.ti.com/litv/pdf/spmu289b]
+ *  Stellaris® LM4F120H5QR Microcontroller [http://www.ti.com/lit/ds/symlink/tm4c1233h6pm.pdf] -- this is actually for Tiva C TM4C1233 MCU, but this is equivalent part to LM4F120H5QR.
+ *  Corresponding Tiva TM4C and Stellaris LM4F part numbers [http://e2e.ti.com/support/microcontrollers/tiva_arm/f/908/t/271820.aspx]
+= Board Setup =
+
+
+The board runs find without any tuning/switching. 
+= Downloading and Executing =
+
+
+See <ref name="Debugging">
+= Debugging =
+
+
+Using OpenOCD >= 0.7.0. This OpenOCD release added Stellaris ICDI support. On Windows I'm using ''bin\openocd-0.7.0.exe -f scripts\board\ek-lm4f120xl.cfg'' to start the debugger. Then I connect to it GNU RTEMS debugger by
+
+''target remote localhost:3333
+monitor reset halt
+load <rtems.exe>
+cont
+''
