1321xNSK-Network Starter Kit

[SrinathBharadwa]

Hi,

Sometime back I bought Freescale 1321xNSK-Network Starter Kit. I am unable to download the code to the micocontroller. I am getting "Error: Cannot enter background mode"

This is the hardware and software Details:
1. CodeWarrior - Version 5.1
2. P&E USB Multilink BDM - Firmware Ver 5.79
3. CPU - MC9S08GB60
4. Micro - 8 bit HCS08 - 13213

My mail id is srinath.bharadwaj@gmail.com

I have attached a error screen shot too.

This is the log in the command window:

I'd suspect hardware issue. I'd suggest you to check if the BDM connector correctly plugged. Isn't it reversed? Are all the BDM connector pins correctly interconnected? Does the yellow and blue leds light?

Hi Stanish,

Thanks for the reply.

Both blue and yellow LEDs are glowing. I suspected might be power is not going to micro. But I checked with oscilloscope. There is sufficient voltage available at VCC pin of micro.

BDM connector is fine because blue led is on. If it is reversed, the yellow led would not glow. In my case yellow led is on. So I think the connection between target and BDM is good.

By any chance did you look at the error screen shot which was attached. It says MCU Reset Line : Low(in red color) and MCU voltage : Vcc > 1.0Volts.

Any idea what this means? 

[stanish]

I would bet on reset pin. Seems to be constantly low so the MCU is still in the reset state and therefore debugger cannot enter background debug mode. Try to figure out what is causing RESET pin low.

Hi,

Sadly my starter kit is still not working. I am still not able to download the code to the micro. I am just testing whether I can download the program or not. And this is my code. It has just main function.

void main(void) {

  EnableInterrupts; /* enable interrupts */
  /* include your code here */

  for(; {
    __RESET_WATCHDOG(); /* feeds the dog */
  } /* loop forever */
  /* please make sure that you never leave main */
}

This code is nothing but auto generated by code warrior itself. I am trying to download this into micro. Out of 'n' no. of times i have tried, i have able to download the code only once. And that was the very first time i flashed. After that it is not happening at all.

Is there is something wrong with the code itself? Is there any way to erase the memory without downlaoding the code?

Regards,
