Hi,
From you screenshot I can see you have multibit ECC fault on address 0x0.
I am not sure how iSystem works but, try to use other debugger.
Lauterbach or PE Micro and erase flash.
In Lauterbach you need to do:
flash.auto.all
flash.erase.all
flash.auto.off
Or try to ask iSystem for help clearing multibit flash ECC faults.
