How do i transfer hex file into 89c51 chip. Im using DB9, max232
and 89c51. I&amp;#39;ve referred to the circuit diagram thats available in
the book (8051) but the thing is its not getting detected. Im using
PROLOAD, EZv1.3,1.4, etc. 
Plz help me out.

Maybe the FLIP utility works. Take a look here:&lt;br /&gt;
&lt;a target="_blank" href="http://www.atmel.com/dyn/products/tools_card.asp?tool_id=2767"&gt;www.atmel.com/.../tools_card.asp&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
Check exactly the device that you are using and make sure that it
is listed.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Serial Comm.</title><link>https://community.arm.com/thread/123578?ContentTypeID=1</link><pubDate>Fri, 22 Dec 2006 10:49:17 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:bdce788b-22e9-4fdf-80d4-41d7eb0a4d45</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
does the Proload &lt;b&gt;hardware&lt;/b&gt; specs (which you do not show a
link to) list your chip?&lt;/p&gt;

&lt;p&gt;
Not trying to insult you, but you do not believe this software
will work without the Proload hardware, do you?&lt;/p&gt;

i&amp;#39;ve used the circuit diagram that is shown in 89c51 datasheet,
&amp;quot;Flash programming &amp;quot;.&lt;/p&gt;

give a link to proload, I have no idea what it is, but a bit of a
read might reveal the answer to your problem.&lt;/p&gt;
