I tested it out on a DEMO9S08QG8 that I have and it worked.
As you've probably noted, the demo and documentation were originally written for CodeWarrior 3.1. So the screen shot and documentation about the debug selection aren't exactly right.
In CW 5.0, the drop down box shows the actually debug device. In 3.1, this was more like the class of debug tools (like PE ICD). You used to select PE ICD and then when you got in the debugger, you'd select the specific debug device.
In your case, in CW 5.0, you would select "P&E Mulitilink/Cyclone Pro." The USB BDM on the demo board is actually the guts of a Multilink 2.0. So when you first connected the board, you should have seen a Multilink 2.0 driver get installed.
You said that you installed a service pack. Hopefully, this was the "CW08 v5.0 Patch 1." This is the only update that you need for CodeWarrior 5.0. This patch also installs a new version of the DEMO9S08QG8_APP that might work better for you. (When I tested, I used the original one off of the demo CD - not this new one.)
If you're still having problems, post back and we'll work on it.
All,
Well, I installed CW 5.0, then the Service Pack (yes, it was "CW08 v5.0 Patch 1") on a different PC, being careful to reboot between/after. Then I connected the DEMO9S08QG8 board, which came up fine. Then I ran the DEMO..._APP software, did the make, debug and flash just fine (with the P&E Multilink / Cyclone Pro selection) and all was well. The pot sweeps from 0x000 to 0x3FF, etc., etc.
Just to verify, I popped the chip, plugged in a new (unflashed) part and flashed it, ran the demo again, etc. No problems.
So it's probably just a mangled install on the first PC. I've had some other CW (3.1) install / remove issues on that PC anyway, so I guess it's time to clean it up in general.
I look forward to an updated set of DEMO..._APP instructions! First for the corrected screen shots for CW 5.0, but also for little items like explicitly instructing you to start your terminal emulator BEFORE you do the flash cycle (so it's ready to receive the demo banner page when the MCU comes back up)! I'm reminded of the cute comic where the guy build a yacht in his basement, then gets to step 4: "Perform steps 1-3 in a large open space near a body of water".
Thanks for the help. Now I'm off to find SCI and IIC demos and figure out my (top secret hush hush!) application.
