Please check that the red wire is connected to the side of the plug that got a small dot.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Also validate that the board is turned on, e.g. plug in the USB plug.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Also our software require Codewarrior 6.1 please make sure you have the latest version installed.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;BR,&lt;/P&gt;&lt;P&gt;Mads&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi Mads,&lt;/P&gt;&lt;P&gt;Thanks for the reply.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Both blue and yellow leds are on. So, I guess connection is good. In fact, i connected an oscilloscope to check whether power is coming to micro and I was able to see some voltage at the Vcc of micro.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Since the board uses HCS08, i&amp;nbsp;am using CW version 5.1. You have suggested me to use version 6.1. So I will check this and will get back to you. I will let you know the status of this.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;Regards,&lt;/P&gt;&lt;P&gt;&amp;nbsp;Srinath Bharadwaj&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;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.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;void main(void) {&lt;/P&gt;&lt;P&gt;&amp;nbsp; EnableInterrupts; /* enable interrupts */&lt;BR /&gt;&amp;nbsp; /* include your code here */&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp; for(;&lt;IMG alt=":smileywink:" class="emoticon emoticon-smileywink" id="smileywink" src="http://freescale.i.lithium.com/i/smilies/16x16_smiley-wink.gif" title="Smiley Wink" /&gt; {&lt;BR /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; __RESET_WATCHDOG(); /* feeds the dog */&lt;BR /&gt;&amp;nbsp; } /* loop forever */&lt;BR /&gt;&amp;nbsp; /* please make sure that you never leave main */&lt;BR /&gt;}&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;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.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Is there is something wrong with the code itself? Is there any way to erase the memory without downlaoding the code?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Regards,&lt;/P&gt;&lt;P&gt;Srinath Bharadwaj&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

I am still not able to download the code and&amp;nbsp;I am still getting the same error.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I am suspecting whether this is something to do with secure and unsecure feature of micro. Is there any way to unsecure a HCS08 micro? Is there any utility available for unsecuring HCS08?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The reason for my doubt is in the memory window all the address locations have "--" instead of data. And also it is not allowing to execute any read or write operations.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks,&lt;/P&gt;&lt;P&gt;Srinath Bhaskaran&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
