ARM-CM4 STM32 Olimex STM32-P405 IAR EWARM

Supported firmware update interfaces

RS232 CAN USB TCP/IP SD-card
Yes Yes Yes No Yes

Development Environment

This demo is targeted towards the Olimex STM32-P405 board, with 1024 kB internal Flash EEPROM and 192 kB internal RAM.

To program the bootloader into the internal flash on the STM32F405 microcontroller, the Segger J-Link JTAG 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 IAR Embedded Workbench for ARM development environment.

Building and programming the Bootloader

Before the bootloader can be used, it needs to be built and programmed into the STM32F405'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 (stm32f405.eww) is located at: \Target\Demo\ARMCM4_STM32F4_Olimex_STM32P405_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 STM32F405. Make sure the Segger J-Link debugger interface is connected to the board and to your PC. 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:

  • \Target\Demo\ARMCM4_STM32F4_Olimex_STM32P405_IAR\Boot\bin\openblt_olimex_stm32p405.out
  • \Target\Demo\ARMCM4_STM32F4_Olimex_STM32P405_IAR\Boot\bin\openblt_olimex_stm32p405.srec

Building the Demo Program

When using IAR EWARM, simply open the workspace from within the Embedded Workbench. The workspace file (stm32f405.eww) is located at: \Target\Demo\ARMCM4_STM32F4_Olimex_STM32P405_IAR\Prog\ide\. Once opened, select Project→Rebuild All from the menu to compile all the demo program sources and link the together into the final executable.

The output file is

  • \Target\Demo\ARMCM4_STM32F4_Olimex_STM32P405_IAR\Prog\bin\demoprog_olimex_stm32p405.srec

Firmware update procedure

To download the demo program \Target\Demo\ARMCM4_STM32F4_Olimex_STM32P405_IAR\Prog\bin\demoprog_olimex_stm32p405.srec using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
