Okay, it's important to separate the sub-problems you're dealing with here. For example, it's important to be clear that the "no hard disk found contact support" message may or may not have anything to do with the builder upgrade not working.
"no hard disk found" will appear on the player's screen when:
1. The disk drive is genuinely not found by the kernel software (for any of the hardware-related reasons
listed in the FAQ). This includes simply plugging the cable in wrong, so definitely check that.
2. The disk drive is working just fine but it's hasn't been properly partitioned by the builder software and/or hasn't had the player software installed on it yet.
Your builder image doesn't seem to be working for you, it never even gets as far as flashing the kernel, it's not even getting to the hard disk yet. So it never gets to the point of trying to pump the partitions. So I'm guessing that the reason "no hard disk found" is appearing is because of #2 above, and there's every reason to believe the disk is fine.
Let's rewind a bit. You said hyperterminal worked, right? This is important, if hyperterminal doesn't work then you've got serial port problems and that's the reason none of this is working. So. Go back to hyperterminal and make sure it works.
If hyperterminal works, watch the boot log and see if the disk drive is detected at boot time. See if you get an error about the CS4132A chip. See if it detects the drive during the "probing primary interface" stage. That sort of thing. The stuff in the FAQ I linked above.
If the drive looks good and Hyperterminal works, then we're on to looking for a reason that the builder image refuses to apply. Are you using a docking sled at all? Click
here if so. Beyond that, go through all the steps
here and see if you can find any reason that the upgrader might not work.
