+FSM-55 LED Matrix Display Board is a simple board to play 5x5 LED
+Display. Please see the product page:
+
+ http://www.seeedstudio.com/depot/FSM55-LED-Matrix-Display-p-2121.html
+
+The file stlink-v2.cfg can be used for ST-Link/V2 with OpenOCD. You
+can flash by typing:
+
+ $ openocd -f ./stlink-v2.cfg -c "program build/hacker-emblem.elf"
+
+Thanks to Kiwamu Okabe who kindly tested OpenOCD and wrote the
+configuration.
