Software Requirements: A) Ubuntu Mate 14.04.3 LTS (Trusty Tahr) for Intel X86; B) GNU Toolchain ARM Cortex-M/R (https://launchpad.net/gcc-arm-embedded); C) OpenOCD (http://openocd.org/) or ST-Link (https://github.com/texane/stlink/); D) Minicom/Cutecom

The project has been testeed under the following environment:

1. Distribution: Ubuntu Mate 14.04.3 LTS (Trusty Tahr), for Intel X86, Kernel Version: 3.16.0-46-generic
2. GCC Version: 4.9.3 20150529 (Release) [ARM /embedded-4_9-branch revision 227977] (GNU Tools for ARM Embedded Processors)
3. Open On-Chip Debugger 0.10.0-dev-00036-g48787e1
4. Cutecom Version 0.22.0-2

How to run the project:

1. Create in the user home directory the hidden file .hdbinit, with the following line: set auto-load safe-path /home/user_home_directory

2. open a terminal and download in the user home directory the following template typing: git clone https://github.com/gnunicky/projct_rai_nucleo_stm32f411re_hal.git

3. Move to the directory magnetic_core_memory_hal: cd project_rai_nucleo_stm32f411re_hal/magnetic_core_memory_hal/

4. Create an additional, hidden file called .gdbinit, required from OpenoCD and GDB, with the following lines: layout split target extended localhost:3333 monitor arm semihosting enable monitor reset halt load monitor reset init

5. Clean and compile the project with following commands:

• make clean
• make

6. Plug the Nucleo STM32F411RE, with the Driver Shield and the IBM DJB 373330, already connected to the board and type the following command:

• make flash_openocd OR make flash_stlink

7. Start the OpenOCD server with following command:

• make openocd

8. Open a terminal in a new consolle and start GDB with following command:

• make debug

9. Start a serial communication program, like minicom/cutecom, setting following parameters: Device=/dev/ttyACM0 Baud Rate: 115200 Parity: None Data Bits: 8 Stop Bits: 1

10. Come back to the screen displaying the debugger interface and insert, one at a time, following commands:

• run
• o
• r

11. Now, from the screen containing the serial communication program, you can interact with the software managing the Magnetic Core Memory.
