JTAG
-------------------------------------------------------------------------------
This is a set of example captures of JTAG communication to an Olimex
STM32-H103 eval board with an ST STM32 (ARM Cortex-M3) microcontroller.
The JTAG adapter used was the FTDI FT2232H based Floss-JTAG (V0.2).
The firmware flashed to the board is a simple LED-blinking libopencm3
example named 'fancyblink'. The respective fancyblink.bin file is
available as a reference in the same directory as this README.
The file's MD5 sum is aa6980d55b9ced84fc0c64bfe9e5ff98.

-------------------------------------
The OpenOCD used was "0.5.0 (2011-08-09-08:45)" (Debian version 0.5.0-1):
openocd -f interface/flossjtag-noeeprom.cfg \
-f board/olimex_stm32_h107.cfg \
-c "init" -c "reset init" \
-c "stm32f1x mass_erase 0" \
