Re: Vida CEM swapping

As I suspected. I've erased the initial stack + PC pointers at top(bottom?) of boot block. Oh yeah. I did it. I BDM'ed the ETM using T5Luke's code. EDIT: I wish to announce with a lot of work, I have managed to revive my ETM. It no longer needs BDM. Patches for T5Luke's Arduino code to allow probing...

I have crafted a small application that will, provided you have a binary dump of an AW55(5 speed), will try and extract the memory address of the adaptation. Then one should note the original value of the adaptation for garage shifts(a...
