Re: running from external memory (microblaze)

MicroBlaze always jumps to 0x8 or something like that on interrupt. The initialization code for your application writes the address of your interrupt handler into this low memory so that when an interrupt occurs, MicroBlaze jumps to the fixed low address and from there to your interrupt handler.

At this moment one thing is not clear to me: how are interrupts handled? The microblaze jumps to address 0x18, but in my case that's the bootloader in block ram. And I want to handle the interrupts in my application of coarse.
