Very surprised at that.
I guess the single one is acting as boot and little else (few processors can boot of dual chip configs).
The answer then is an ICE or BDM
No, they don`t boot as a dual configuration. If you read the emulated section, there is actually very little data in either of them - I think this is nothing more than an exercise is annoying the decoding fraternity!
Be aware that simply reading and attempting cloning of the flash chip itself may not be enough to actually clone the chip. Not much experience of this particular Vx model, but for instance, similar setup used in Alfa Romeo & Porsche units and you have to boot the flash device before you can read the entire code data area. Once you have booted the chip you will be staggered at the readings and how they differ from that taken by simply "reading" the flash memory.
If you manage to crack that one, then come and see me, as there will be a desk and a job here waiting for you !!
