| 5 | This is a set of example captures of JTAG communication to an Olimex | |
| 6 | STM32-H103 eval board with an ST STM32 (ARM Cortex-M3) microcontroller. | |
| 7 | ||
| 8 | The JTAG adapter used was the FTDI FT2232H based Floss-JTAG (V0.2). | |
| 9 | ||
| 10 | The firmware flashed to the board is a simple LED-blinking libopencm3 | |
| 11 | example named 'fancyblink'. The respective fancyblink.bin file is | |
| 12 | available as a reference in the same directory as this README. | |
| 13 | The file's MD5 sum is aa6980d55b9ced84fc0c64bfe9e5ff98. | |
