Prefetch exception after interrupt remapping

Posted on December 18, 2008 at 11:59

Hi All,

i am using str73x processor for my development. I am developing bootlaoder for my processor. i have application program which needs to download into processor via bootloader. I remap my interrupt in application code and whenever i enable the interrupt, my code loops into prefetch execption loop (code works fine without interrupt enabling)

i traced out the code by debugger whenever interrupt comes IRQ handler gets called and it then check for the interrupt source and then loop in prefetch execption.

i my code memory loacted at 0x80020000 (by default it is 0x80000000 where my bootloader code resides) interrupt is remapped to the RAM

Can someone help me analyse this problem.

Thanks
