Interrrupts During IAP

Anu Ambre

Hi,

I am working on LPC2468.

I able to use IAP with disabling Interrupts,but I want some interrupts to work even with IAP.

I can done this with remapping of interrupt vectors in RAM & executing it from RAM itself.

Anyone can help me out for this.

    If you look at older threads, you'll find that I have written in a number of threads about creating boot loaders. A boot loader has similar requirements - that the application runs with a remapped interrupt vector table in RAM.

    Next thing is that you can configure the project so that the linker places important ISR in RAM. As long as the ISR doesn't call any of your functions or any compiler-specific helper function, you will be able to handle interrupts without touching the flash.
