@par Application Description
|
|
|
|
This directory contains a set of sources files that build the application to be
|
|
loaded into Flash memory using In-Application Programming (IAP, through USART).
|
|
|
|
To build such application, some special configuration has to be performed:
|
|
1. Set the program load address at 0x08004000, using your toolchain linker file
|
|
2. Relocate the vector table at address 0x08004000, using the "NVIC_SetVectorTable"
|
|
function.
|
|
|
|
@note Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds)
|
|
based on variable incremented in SysTick ISR. This implies that if HAL_Delay() is called from
|
|
a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower)
|
|
than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
|
|
To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.
|
|
|
|
@note The application need to ensure that the SysTick time base is always set to 1 millisecond
|
|
to have correct HAL operation.
|
|
|
|
Four LEDs are toggled with a timing defined by the Delay function.

@par Hardware and Software environment
|
|
|
|
- This application runs on STM32F429xx/STM32F439xx devices.
|
|
|
|
- This application has been tested with STM324x9I-EVAL board revB and can be
|
|
easily tailored to any other supported device and development board.
|
|
|
|
@par How to use it ?
|
|
|
|
In order to load the SysTick example with the IAP, you must do the following:
|
|
|
|
- EWARM:
|
|
- Open the Project.eww workspace
|
|
- Rebuild all files
|
|
- A binary file "STM324x9I-EVAL_SysTick.bin" will be generated under "STM324x9I-EVAL/Exe" folder.
|
|
- Finally load this image with IAP application
|
|
|
|
- MDK-ARM:
|
|
- Open the Project.uvproj project
|
|
- Rebuild all files: Project->Rebuild all target files
|
|
- Go to "/IAP_Binary_Template/MDK-ARM" directory and run "axftobin.bat"
|
|
(Fromelf Exe path might have to be updated in "axftobin.bat" file, according to your Keil setup).
|
|
- A binary file "STM324x9I-EVAL_SysTick.bin" will be generated under "STM324x9I-EVAL" folder.
|
|
- Finally load this image with IAP application
|
|
|
|
- STM32CubeIDE:
|
|
- Open STM32CubeIDE toolchain
|
|
- Browse to the STM32CubeIDE workspace directory, select the project
|
|
(.project file in \IAP_Binary_Template\STM32CubeIDE \STM324x9I-EVAL directory).
|
|
- Rebuild all project files: Select the project in the "Project explorer" window
|
|
then click on Project->build project menu.
|
|
- Load this image with the IAP application (Select option 1 in IAP_Main menu)
|
