I'm trying to help a friend get his CM working but have spotted a gap in the documentation
After he's typed:
pi@raspberrypi ~/tools/usbboot $ sudo ./rpiboot
he reports getting another prompt, I've told him:
After that you should get a message something like "looking for BCM2835"
and then when it finds the Compute module half a dozen lines ending to the effect of: .. your device is now a mass storage device you can see it with ... (The instructions don't list the messages and my memory is fallible!)
