This demo is targeted towards the STM32F0-Discovery board, with 64 kB internal Flash EEPROM and 8 kB internal RAM.
To program the bootloader into the internal flash on the STM32F051 microcontroller, the on-board ST-Link Debugger Interface was used. However, this is not required if you have another means of programming the internal flash.
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 0.42.
The Olimex USB-Serial-Cable-F was used to create a connection between the STM32F051 USART2 serial peripheral and the PC's COM-port. The pin connections are as follows:
Before the bootloader can be used, it needs to be built and programmed into the STM32F051'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_STM32_Discovery_STM32F051_GCC\Boot\ide\stm32f0.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 STM32F051. Make sure the ST-Link Debugger Interface on the STM32F0-Discovery board is connected to your PC via a 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 memory.
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:
When using Rowley CrossWorks, simply open the project from within CrossWorks. The project file is located at: \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_Crossworks\Prog\ide\
The output file is
