;* File Name : startup_stm32f4xx.s

;* Version : V1.0.0
|
||||
;* Date : 30-September-2011
|
||||
;* Description : STM32F4xx devices vector table for EWARM toolchain.
|
||||
;* This module performs:
|
||||
;* - Set the initial SP
|
||||
;* - Set the initial PC == _iar_program_start,
|
||||
;* - Set the vector table entries with the exceptions ISR
|
||||
;* address.
|
||||
;* - Configure the system clock and the external SRAM mounted on
|
||||
;* STM324xG-EVAL board to be used as data memory (optional,
|
||||
;* to be enabled by user)
|
||||
;* - Branches to main in the C library (which eventually
|
||||
;* calls main()).
|
||||
;* After Reset the Cortex-M4 processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

; The modules in this file are included in the libraries, and may be replaced

; To override the cstartup defined in the library, simply add your modified

;
|

; The vector table is normally located at address 0.
|
||||
; When debugging in RAM, it can be located in RAM, aligned to at least 2^6.
|

; The name "__vector_table" has special meaning for C-SPY:
|
||||
; it is where the SP start value is found, and the NVIC vector
|
||||
; table register (VTOR) is initialized to this address if != 0.

|
||||
* @version V1.0.0
|
||||
* @date 24-October-2011
|
||||
* @brief CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
|
||||
* This file contains the system clock configuration for STM32F4xx devices,
|
||||
* and is generated by the clock configuration tool
|
||||
* stm32f4xx_Clock_Configuration_V1.0.0.xls
|
||||
*
|
||||
* 1. This file provides two functions and one global variable to be called from
|
||||
* user application:
|
||||
* - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
|
||||
* and Divider factors, AHB/APBx prescalers and Flash settings),
|
||||
* depending on the configuration made in the clock xls tool.
|
||||
* This function is called at startup just after reset and
|
||||
* before branch to main program. This call is made inside
|
||||
* the "startup_stm32f4xx.s" file.
|
||||
*
|
||||
* - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
|
||||
* by the user application to setup the SysTick
|
||||
* timer or configure other parameters.
|
||||
*
|
||||
* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
|
||||
* be called whenever the core clock is changed
|
||||
* during program execution.
|
||||
*
|
||||
* 2. After each device reset the HSI (16 MHz) is used as system clock source.
|
||||
* Then SystemInit() function is called, in "startup_stm32f4xx.s" file, to
|
||||
* configure the system clock before to branch to main program.
|
||||
*
|
||||
* 3. If the system clock source selected by user fails to startup, the SystemInit()
|
||||
* function will do nothing and HSI still used as system clock source. User can
|
||||
* add some code to deal with this issue inside the SetSysClock() function.
|
||||
*
|
||||
* 4. The default value of HSE crystal is set to 25MHz, refer to "HSE_VALUE" define
|
||||
* in "stm32f4xx.h" file. When HSE is used as system clock source, directly or
|
||||
* through PLL, and you are using different crystal you have to adapt the HSE
|
||||
* value to your own configuration.
|
||||
*
|
||||
* 5. This file configures the system clock as follows:
