FreeRTOS with NXP LPC2468 and Keil

Dennis Bruch

Hello at all,

I want to use FreeRTOS with the NXP LPC2468. On the website http://www.freertos.org exists only an example with the LPC2129 and Keil
(look here "www.freertos.org/index.html://interactive.freertos.org/entries/156159-lpc23xx-port-with-keil-rv-compiler").

How can I use this example for the LPC2468? Exists there better examples?

How can I change the file "startup.s" and the port of FreeRTOS?

    Note that whether an application needs heap is very application specific (but you indicate that it is needed always, so it seems).

    Also,

    "When the main() starts, you are in supervisor mode and interrupts are disable.
    If you need to enable interrupts before calling vTaskStartScheduler() you need to call __enable_irq()."

    If you enter main in user mode and then call a SWI to start FreeRTOS, this requirement is implicitly satisfied!
