@par Example Description
|
|
|
|
How to build an application to be loaded into the NOR memory mounted on board
|
|
and then execute it from internal Flash memory.
|
|
|
|
At the beginning of the main program the HAL_Init() function is called to reset
|
|
all the peripherals, initialize the Flash interface and the systick.
|
|
Then the SystemClock_Config() function is used to configure the system
|
|
clock (SYSCLK) to run at 72 MHz.
|
|
|
|
In order to make the program work, you must do the following:
|
|
|
|
1. Program the NOR memory with the example provided in the "binary" directory
|
|
@note You can use ST-LINK v3.4.6 tool and select NOR Flash memory in the external loader and
|
|
then flash the binary file at @0x64000000.
|
|
|
|
2. Program the internal Flash with the code that will jump to the NOR memory to execute
|
|
the loaded example.
|
|
|
|
@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.
|
|

@par Hardware and Software environment
|
|
|
|
- This example runs on STM32F1xx devices.
|
|
|
|
- This example has been tested with STM3210E-EVAL RevD board and can be
|
|
easily tailored to any other supported device and development board.
|
|
|
|
@par How to use it ?
|
|
|
|
In order to make the program work, you must do the following :
|
|
- Open your preferred toolchain
|
|
- Rebuild all files and load your image into target memory
|
|
- Run the example
