Right, it's meant to be complementary to the new firmware... but it is still supposed to work without it. Are you running it via a pc plugged into it and it never starts the device at all with 0.2 firmware?
I'm running on the RPI. Everything works with 4.0.0, compiled from Git. When I run 4.0.1 is just shows "Failed to receive OP_NAME response" over and over again.
