[ECOS] Int Vector table ARM 7 Integrator

[Leo McManus <leomcmanusir at yahoo dot com>]

QUESTIONS:
I wish to know if the interrupt vector table should be modified on an ARM720T
Integrator board after I attach with my gdb over serial?

Where is the addresses for my ISR put when I call cyg_interrupt_create() ?

Does the RedBoot have control of the vertor table and sets this up when it boot
and any program I download is expected not to modify this area?

SETUP:
I have RedBoot on my ARM integrator board on which I have burnt RedBoot. I
attatch to the board over the serial line.  I examine the Vector table at
address 0. If I now download my program and start stepping into my code, by the
time I hit my main, the Vector table has not been changed and holds high
addresses: 0xe59ff018 in 7 of first 8 long words and 0x59dff5ab in the NOP
vector.

My ROM vectors are updated when I down load my program, address 0x40000.

Could there be something I have missed when I ran the configure program? Is
there something fundamental I can look for in the .ecc file?

Thanks

Leo
