In order to make the program work, you must do the following: 1. Generate a binary image using the preconfigured project provided in the directory "Project\STM32F4xx_IAP\binary_template" . 2. Program the internal Flash with the IAP (see below) 3. Open HyperTerminal window using the settings already defined in section "Hardware and Software environment" 4. To run the IAP application, keep the Key push-button pressed at Reset. The IAP main menu is then displayed on the HyperTerminal window. 5. To download an application, press 1 and use the Ymodem protocol In order to load the IAP code, you have do the following: - EWARM - Open the Project.eww workspace - Rebuild all files: Project->Rebuild all - Load project image: Project->Debug - Run program: Debug->Go(F5) - RIDE - Open the Project.rprj project - Rebuild all files: Project->build project - Load project image: Debug->start(ctrl+D) - Run program: Debug->Run(ctrl+F9) - MDK-ARM - Open the Project.uvproj project - Rebuild all files: Project->Rebuild all target files - Load project image: Debug->Start/Stop Debug Session - Run program: Debug->Run (F5) - TASKING - Open TASKING toolchain. - Click on File->Import, select General->'Existing Projects into Workspace' and then click "Next". - Browse to TASKING workspace directory and select the project: - STM324xG-EVAL: to configure the project for STM32F4xx devices. - Under Windows->Preferences->General->Workspace->Linked Resources, add a variable path named "Cur_Path" which points to the folder containing "Libraries", "Project" and "Utilities" folders. - Rebuild all project files: Select the project in the "Project explorer" window then click on Project->build project menu. - Run program: Select the project in the "Project explorer" window then click Run->Debug (F11) - TrueSTUDO - Open the TrueSTUDIO toolchain. - Click on File->Switch Workspace->Other and browse to TrueSTUDIO workspace directory. - Click on File->Import, select General->'Existing Projects into Workspace' and then click "Next". - Browse to the TrueSTUDIO workspace directory, select the project: - STM324xG-EVAL: to configure the project for STM32F4xx devices - Under Windows->Preferences->General->Workspace->Linked Resources, add a variable path named "CurPath" which points to the folder containing "Libraries", "Project" and "Utilities" folders. - Rebuild all project files: Select the project in the "Project explorer" window then click on Project->build project menu. - Run program: Run->Debug (F11) * <h2><center>&copy; COPYRIGHT 2011 STMicroelectronics</center></h2> */
