ARM-CM0 STM32 Nucleo-F091RC GCC

Supported firmware update interfaces

UART CAN USB TCP/IP SD-card
Yes Yes No No No

Development Environment

This demo is targeted towards the Nucleo-F091RC board, with 256 kB internal Flash EEPROM and 32 kB internal RAM.

To compile the demo programs you can use the EmBitz development environment from Em::Blocks. The version that was used to create these demo programs was EmBitz version 1.00.

To program the bootloader into the internal flash, the on-board ST-Link debugger interface was used. Firmware updates via the serial communication port are preconfigured to use the virtual COM-port offered by the ST-Link. This means that no additional hardware is needed, besides a standard micro-USB cable.

Building and programming the Bootloader

Before the bootloader can be used, it needs to be built and programmed into the STM32F091's internal flash memory. The steps in this section only need to be done once.

When using EmBitz, simply open the project file by double-clicking the file: \Target\Demo\ARMCM0_STM32F0_Nucleo_F091RC_GCC\Boot\ide\stm32f091.ebp from the Windows Explorer. To build the bootloader, select Build → Rebuild all target files from the program menu.

The bootloader program is now ready to be programmed into the internal flash memory of the STM32F091. Make sure the board is connected to your PC via a micro-USB cable. Next, select Debug → Start Debug Session (F8) from EmBitz's program menu to flash the bootloader program. Once done, you can start the bootloader program by selecting Debug → Run (F5) from the program's menu.

Alternatively, you can use your favorite programmer to flash the bootloader using one of the following files, depending on what file type your programmer supports:

  • \Target\Demo\ARMCM0_STM32F0_Nucleo_F091RC_GCC\Boot\bin\openblt_stm32f303.elf
  • \Target\Demo\ARMCM0_STM32F0_Nucleo_F091RC_GCC\Boot\bin\openblt_stm32f303.srec

Building the Demo Program

When using EmBitz, simply open the project file by double-clicking the file: \Target\Demo\ARMCM0_STM32F0_Nucleo_F091RC_GCC\Prog\ide\stm32f091.ebp from the Windows Explorer. To build the demo program, select Build → Rebuild all target files from the program's menu.

The output file is

  • \Target\Demo\ARMCM0_STM32F0_Nucleo_F091RC_GCC\Prog\bin\demoprog_stm32f091.srec

Firmware update procedure

To download the demo program \Target\Demo\ARMCM0_STM32F0_Nucleo_F091RC_GCC\Prog\bin\demoprog_stm32f091.srec using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
