What version of CW ? Click Help/About Intalled Products.

- Did the flash get programmed?
- Did it run to main and halt?
If so, press F5, which is Start/Continue or click the green arrow.

We need more information to help you...

Thanx, for your kind reply. I observed a strange problem.

From last two days I want to run the example for HCS12DP256B give at following path C:\Program Files\Freescale\CW for HC12 V4.5\(CodeWarrior_Examples)\MC9S12\DP\DP256B.

C:\Program Files\Freescale\CW for HC12 V4.5\(CodeWarrior_Examples)\MC9S12\DP\DP256B.

Due to that reason I connected a null modem RS-232 cable to M68KIT912DP256 to see serial output . After that I performed steps as follow.

1) Install the Multilink driver that was download from www.pemicro.com. I am using WINXP and Multilink device was not shown in the device manager.

2) Check the entire jumper setting that was same as u wrote in your mail.

3) Then connect USB MULTILINK to the PC the Multilink blue LED became ON.

4) Then I powered up the KIT. Multilink Yellow LED become ONand Bargraph on the Kit was glowing.

5) Run the Real-Time Simulator and debugger by click on the Icon of DEBUG. But no connection was made.

After it I disconnect all cables and then again make all connections but RS-232 cable did not attach. But this time only blue light was ON though Kit was powered then I connect the RS232 cable with Powered KIT then Yellow light became ON.

I repeat this process many times again but

I conclude that may be there was a unknown wrong jumper setting or Multilink is not functioning proper or winxp driver is not recognizing the Multilink

Please guide me soon because I have to complete given task with finite time.

You might have accidently secured the HCS12. If it is secured, no BDM access works before the flash is erased. There is a program called "Unsecure 12" which is available for free from PE micro. Try that one and see if it helps.

I am sorry but there are many things in your post that are not clear to me,

However, I can tell you this concerning the Multilink:
Blue LED on = Driver installed and working with Multilink

Yellow LED On = Plugged in, BUT can be connected backwards and still get yellow LED.

- Try plugging in with the plug the other way around. I don't have this board, but most boards have a number '1' which is where the RED STRIPE side should go.

Further comments:

The multilink will not show up in device manager until you plug it in.

Do you get the USB Sound and/or bubble when you unplug it and replug it?

After you plug it in and the blue LED comes on, look in device manager for "Jungo"

Dear Jim,

Yes its is true when i connect Multilink then USB sound is listened by me. And blue LED glows. BUT when i Powered UP the board then yellow LED does not glow.

I connect the multilink in correct direction. i.e RED wire on PIN 1 of BDM In connector i.e J19.

Ok, well the yellow LED will not come on unless the board is powered.

You should have some sort of AC adaptor or power supply.
There also may be jumpers that must in the correct positions.

Please veryify the there is a proper 5V supply coming to the board.

Dear JIm,

I alrady confirm that all jumpers are at proper position and there are 5 volt supply on the board. And already programmed Firmware is working properly.

thanx

Well, at this point my only idea is that the hardware is bad.

I would submit service ticket on the P&E Web site and explain that:

- The Blue LED lites up and the driver seems loaded.
- The board comes up and runs the Demo program.
- The Yellow LED never comes on, and you can't connect to the board.
(Assuming all that is correct)

You may have to register and log in to get to that page. My past experience with P&E have been very positive.
