To build such application, some special configuration has to be peformed: 1. Set the program load address at 0x08003000, using your toolcahin linker file 2. Relocate the vector table at address 0x08003000, using the "NVIC_SetVectorTable" function. The SysTick example provided within the STM32F10x Standard Peripheral examples is used as illustration. This example configures the SysTick to generate a time base equal to 1 ms. The system clock is set to 72 MHz, the SysTick is clocked by the AHB clock (HCLK) A "Delay" function is implemented based on the SysTick end-of-count event. Four LEDs connected to the GPIO_LED Pin 6, Pin 7, Pin 8 and Pin 9 are toggled with a timing defined by the Delay function. Directory contents ================== + binary_template\EWARMv5: This folder contains a pre-configured project file that produces a binary image of SysTick example to be loaded with DFU. + binary_template\RIDE: This folder contains a pre-configured project file that produces a binary image of SysTick example to be loaded with DFU. + binary_template\RVMDK: This folder contains a pre-configured project file that produces a binary image of SysTick example to be loaded with DFU. + binary_template\inc: contains the binary_template firmware header files - platform_config.h Evaluation board specific configuration file - stm32f10x_conf.h Library Configuration file - stm32f10x_it.h Header for stm32f10x_it.c - main.h Header for main.c + binary_template\src: contains the binary_template firmware source files - main.c Main program - stm32f10x_it.c Interrupt handlers Hardware environment ==================== This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation boards and can be easily tailored to any other hardware. To select the STMicroelectronics evaluation board used to run the example, uncomment the corresponding line in platform_config.h file. + STM3210B-EVAL - Use LD1, LD2, LD3 and LD4 leds connected respectively to PC.06, PC.07, PC.08 and PC.09 pins + STM3210E-EVAL - Use LD1, LD2, LD3 and LD4 leds connected respectively to PF.06, PF0.7, PF.08 and PF.09 pins How to use it ============= In order to load the SysTick example with the DFU, you must do the following: + EWARMv5 - Open the SysTick.eww workspace - In the workspace toolbar select the project config: - STM3210B-EVAL: to configure the project for STM32 Medium-density devices - STM3210E-EVAL: to configure the project for STM32 High-density devices - Rebuild all files: Project->Rebuild all - A binary file "SysTick.bin" will be generated under "STM3210E-EVAL\Exe" or "STM3210B-EVAL\Exe" folder depending on configuration you selected + RIDE - Open the SysTick.rprj project - In the configuration toolbar(Project->properties) select the project config: - STM3210B-EVAL: to configure the project for STM32 Medium-density devices - STM3210E-EVAL: to configure the project for STM32 High-density devices - Rebuild all files: Project->build project - Go to "Utilities\Binary" and run "hextobin.bat" - A binary file "SysTick.bin" will be generated under "\STM3210E_EVAL" or "\STM3210B_EVAL" folder depending on configuration you selected + RVMDK - Open the SysTick.Uv2 project - In the build toolbar select the project config: - STM3210B-EVAL: to configure the project for STM32 Medium-density devices - STM3210E-EVAL: to configure the project for STM32 High-density devices - Rebuild all files: Project->Rebuild all target files - Go to "Utilities\Binary" and run "axftobin.bat" - A binary file "STM3210B-EVAL_SysTick.bin" or "STM3210E-EVAL_SysTick.bin" will be generated under "\Obj" folder + The generated .bin file should be converted to the DFU format using the “DFU File Manager Tool” included in the “DfuSe” PC software install. For more details on how to convert a .bin file to DFU format please refer to the UM0412 user manual “Getting started with DfuSe USB device firmware upgrade STMicroelectronics extension” available from the STMicroelectronics microcontroller website www.st.com. NOTE: - Low-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 32 and 128 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. ******************* (C) COPYRIGHT 2009 STMicroelectronics *****END OF FILE******
