Microprocessor systems in telecommunications

Learning material and examples for course TK402 at FE Tuzla

Software requirements

For this course you need to have:

• Linux operating system (Ubuntu),
• Code editor (Geany,Vim,etc...)

Hardware requirements

For this course we will need following components:

• STM32F407 Disco Board (https://www.st.com/en/evaluation-tools/stm32f4discovery.html)
• USB 2.0 to TTL UART Serial Converter CP2102 (https://www.ebay.com/itm/1PCS-6Pin-USB-2-0-to-TTL-UART-Serial-Converter-CP2102-STC-Replace-Ft232/284022352349?hash=item42210d29dd:g:1y4AAOSwLTZfbBhs)
• Wire jumpers [MM,FF,MF] (https://www.ebay.com/itm/40PCS-20cm-2-54MM-FF-FM-MM-Dupont-wire-jumper-cables-male-to-female-For-Arduino/312724733910?hash=item48cfd8bfd6:g:05sAAOSwlbZdSZ6E)

Toolchain setup

1. Install editor of your choice. We will be using Geany. To install geany run following commands in the terminal

sudo apt-get update

sudo apt-get install geany

2. Open geany and go to the Edit->Preferences->Tools. Change the line

x-terminal-emulator -e "/bin/sh %c"

to

gnome-terminal -x "/bin/sh" %c

Save the changes and inside the terminal run the following command:

sudo apt-get install libvte-dev

After this, restart the geany and in the left bottom corner you should see the tab Terminal.

3. Clone the GitHub repository.
4. Copy the udev rules by executing following command

sudo cp docs/49-stlinkv2.rules /etc/udev/rules.d/

udevadm control --reload-rules && udevadm trigger

5. Change the directory to examples/LAB01/blink-soft-circle/ and runk the following command

make

You should see following output:

arm-none-eabi-objcopy -O ihex main.elf main.hex
arm-none-eabi-objcopy -O binary main.elf main.bin
ls -l main.bin
-rwxrwxr-x 1 student student 3484 Nov 5 13:23 main.bin

6. Install the Linux system libraries

sudo apt-get install build-essential git flex bison libgmp3-dev libmpfr-dev

sudo apt-get install libncurses5-dev libhidapi-hidraw0

sudo apt-get install libmpc-dev autoconf texinfo libtool libftdi-dev

sudo apt-get install libusb-1.0-0-dev zlib1g zlib1g-dev python-yaml

sudo apt-get install libc6-i386

7. Connect you STM32 Disco board

8. Run the following command

make upload

You should see following output:

Error: Old ST-LINK firmware version. Upgrade ST-LINK firmware
Error: Old ST-LINK firmware version. Upgrade ST-LINK firmware
Error: Old ST-LINK firmware! Please upgrade it.

Makefile:53:recipe for target 'upload' failed
make: *** [upload] Error 1

9. You should see LEDs turning On and Off on your disco board.

10. Install the picocom by running following command in terminal

sudo apt-get install picocom

ST-Link Firmware upgrade

1. Connect you STM32 Disco board
2. Change your current position to the stmcubeprog/bin folder

cd stmcubeprog/bin/

3. Run the STMCubeProg by executing following command.

sudo ./STM32CubeProgrammer

4. Click on the firmware upgrade button
5. You should see following window. Click on the Open in update mode.
6. You should be able to click on the Upgrade button.
7. Wait for the upgrade procedure to finish. If the upgrade procedure was successfull you should see following output.
8. You should be able now to successfully run command make upload from the terminal.
