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 IAR Embedded Workbench for ARM development environment.
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.
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 IAR EWARM, simply open the workspace from within the Embedded Workbench. The workspace file (stm32f091.eww) is located at: \Target\Demo\ARMCM0_STM32F0_Nucleo_F091RC_IAR\Boot\ide\. Once opened, select Project→Rebuild All from the menu to compile all the bootloader sources and link them together into the final executable.
The bootloader program is now ready to be programmed into the internal flash memory of the STM32F091. Make sure the ST-Link Debugger Interface on the Nucleo-F091RC board is connected to your PC via a USB cable. Next, select Project → Download and Debug (Ctrl+D) from the menu to flash the bootloader program. Once done, you can start the bootloader program by selecting Debug → Go (F5) from the 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:
