This demo is targeted towards the STM32F3-Discovery board, with 256 Kb internal Flash EEPROM and 48 Kb internal RAM.
To program the bootloader into the internal flash, the on-board ST-Link debugger interface was used (USB ST-LINK connector). Firmware updates via USB use the USB USER connector on the board. This means that no additional hardware is needed, besides a standard micro-USB cable.
To compile the demo programs you can use the IAR Embedded Workbench for ARM development environment.
Before the bootloader can be used, it needs to be built and programmed into the STM32F303's internal flash memory. The steps in this section only need to be done once.
To build the bootloader, open a command prompt in directory \Target\Demo\ARMCM4_STM32F3_Discovery_F303VC_GCC\Boot\ and run the command:
make clean all
The expected output is:
+++ Cleaning build environment +++ Clean complete +++ Assembling [startup_stm32f303xc.s] +++ Compiling [main.c] +++ Compiling [hooks.c] ... +++ Linking [openblt_stm32f303.elf] ... +++ Build complete [openblt_stm32f303.srec]
The bootloader program is now ready to be programmed into the internal flash memory of the STM32F303. Using your favorite programmer (i.e. OpenOCD or STM32 ST-Link utility), flash the bootloader using one of the following files, depending on what file type your programmer supports:
To build the user program, open a command prompt in directory \Target\Demo\ARMCM4_STM32F3_Discovery_F303VC_GCC\Prog\ and run the command:
make clean all
The expected output is:
+++ Cleaning build environment +++ Clean complete +++ Assembling [startup_stm32f303xc.s] +++ Compiling [timer.c] +++ Compiling [main.c] ... +++ Linking [demoprog_stm32f303.elf] ... +++ Build complete [demoprog_stm32f303.srec]
The output file is
To download the demo program \Target\Demo\ARMCM4_STM32F3_Discovery_F303VC_GCC\Prog\bin\demoprog_stm32f303.srec using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
For firmware updates via USB, keep in mind that the USB cable should be connected to the USB USER connector on the board and not the USB ST-LINK connector.
