Got my new Mk2 and i want to replace 1.02 as the player reports or 1.03 as the kernel reports with 2.0b7

I am pretty sure my connection to the empeg is OK, cause i can "cat /dev/tts/0" and then power cycle the empeg to see the boot messgeas.

But when i run emptool it just says
empeg-car Upgrade client.
empegupgrade: Using upgrade file '../car2-consumer-v2.00-beta7.upgrade' to device '/dev/tts/0' (115200 baud)
Checking upgrade file integrity [100%]
Pumping player software
Upgrade file checked [100%]
ERROR: 5 empeg unit not found

Upgrade failed :-(

Upgrade failed with error 0x8004004c
Note that it doesn't wait looking for the unit, it exits out with that error pretty much instantly.
