ARM-CM3 STM32 Olimex STM32P103 GCC

Supported firmware update interfaces

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

Development Environment

This demo is targeted towards the Olimex STM32P103 board, with 128 kB internal Flash EEPROM and 20 kB internal RAM.

To program the bootloader into the internal flash on the STM32F103 microcontroller, the Olimex ARM-USB-TINY-H JTAG interface was used in combination with OpenOCD 0.4.0. However, this is not required if you have another means of programming the internal flash.

To compile the demo programs with Codesourcery G++ Lite (Target OS EABI), you can invoke the make utility from the command line.

Building and programming the Bootloader

Before the bootloader can be used, it needs to be built and programmed into the STM32F103's internal flash memory. The steps in this section only need to be done once.

Batch files are added to aid in building the software program. First clean the bootloader program by double-clicking the file “\Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Boot\cmd\clean.bat”. Next, build the bootloader program by double-clicking the file “\Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Boot\cmd\build.bat”. The output should look like:

+++ Compiling [hooks.o]

+++ Compiling [main.o]

+++ Compiling [boot.o]

...

+++ Linking [openbtl_olimex_stm32p103.elf]

...

+++ Build complete [openbtl_olimex_stm32p103.srec]

The bootloader program is now ready to be programmed into the internal flash memory of the STM32F103. Using your favorite programmer, flash the bootloader using one of the following files, depending on what file type your programmer supports:

  • \Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Boot\bin\openbtl_olimex_stm32p103.elf
  • \Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Boot\bin\openbtl_olimex_stm32p103.srec

Building the Demo Program

Batch files are added to aid in building the demo program. First clean the demo program by double-clicking the file “\Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Prog\cmd\clean.bat”. Next, build the demo program by double-clicking the file “\Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Prog\cmd\build.bat”. The output should look like:

+++ Compiling [boot.c]

+++ Compiling [main.c]

...

+++ Linking [demoprog_olimex_stm32p103.elf]

...

+++ Build complete [demoprog_olimex_stm32p103.srec]

The output file is

  • \Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Prog\bin\demoprog_olimex_stm32p103.srec

Firmware update procedure

To download the demo program \Target\Demo\ARMCM3_STM32_Olimex_STM32P103_GCC\Prog\bin\demoprog_olimex_stm32p103.srec using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
