|

* FreeRTOS.org requires two interrupts - a tick interrupt generated from a

* timer source, and a spare interrupt vector used for context switching.
|

* The configuration below uses PIT0 for the former, and vector 16 for the

||||
* latter. **IF YOUR APPLICATION HAS BOTH OF THESE INTERRUPTS FREE THEN YOU DO
|
||||
* NOT NEED TO CHANGE ANY OF THIS CODE** - otherwise instructions are provided
|
||||
* here for using alternative interrupt sources.
|
||||
*
|
||||
* To change the tick interrupt source:
|
||||
*
|
||||
* 1) Modify vApplicationSetupInterrupts() below to be correct for whichever
|
||||
* peripheral is to be used to generate the tick interrupt.
|
||||
*
|
||||
* 2) Change the name of the function __cs3_isr_interrupt_119() defined within
|
||||
* this file to be correct for the interrupt vector used by the timer peripheral.
|
||||
* The name of the function should contain the vector number, so by default vector
|
||||
* number 119 is being used.
|
||||
*
|
||||
* 3) Make sure the tick interrupt is cleared within the interrupt handler function.
|
||||
* Currently __cs3_isr_interrupt_119() clears the PIT0 interrupt.
|
||||
*
|
||||
* To change the spare interrupt source:
|
||||
*
|
||||
* 1) Modify vApplicationSetupInterrupts() below to be correct for whichever
|
||||
* interrupt vector is to be used. Make sure you use a spare interrupt on interrupt
|
||||
* controller 0, otherwise the register used to request context switches will also
|
||||
* require modification.
|
||||
*
|
||||
* 2) Change the definition of configYIELD_INTERRUPT_VECTOR within FreeRTOSConfig.h
|
||||
* to be correct for your chosen interrupt vector.
|
||||
*
|
||||
* 3) Change the name of the function __cs3_isr_interrupt_127() within portasm.S
|
||||
* to be correct for whichever vector number is being used. By default interrupt
|
||||
* controller 0 number 16 is used, which corresponds to vector number 127.

FILE : startcf.h

PURPOSE : startup code for ColdFire
|
||||
LANGUAGE: C
|
||||
|
||||
|
||||
Notes:
|
||||
1) Default entry point is _startup.
|
||||
. disable interrupts
|
||||
. the SP is set to __SP_AFTER_RESET
|
||||
. SP must be initialized to valid memory
|
||||
in case the memory it points to is not valid using MEMORY_INIT macro
|
||||
2) __initialize_hardware is called. Here you can initialize memory and some peripherics
|
||||
at this point global variables are not initialized yet
|
||||
3) After __initialize_hardware memory is setup; initialize SP to _SP_INIT and perform
|
||||
needed initialisations for the language (clear memory, data rom copy).
|
||||
4) void __initialize_system(void); is called
|
||||
to allow additional hardware initialization (UART, GPIOs, etc...)
|
||||
5) Jump to main
