Hi to all, I'm using KDS 3.2.0, SDK 1.3.0 and P&E Multilink on a proprietary K64 board.

There is no problem at all to debug if I burn the flash: everything's OK.

I've got a problem into "attach" mode:

It correctly attach to my application (still running) and I can pause it, see registers, memory and so on,

but when I try to step and/or "run" the system very often jump to some kind of exception. It breaks into this endless loop:

DefaultISR: b DefaultISR


Of course the watch-dog is disabled.... and there isn't any external reset.


In the attach mode also the "restart button" doesn't work at all: it doesn't change the PC. Please note that it works correctly when I debug burning the flash !!!


Any suggestion ?
