I am working on AT89C51, the problem is that although my assembly
code is working perfectly on the pinnacle simulator it gives a
verification failed error when I try to write it on the programmer
using ezdl4 s/w.

nope,&lt;/p&gt;

the purpose of a forum is that everybody can see (and possibly
learn) from the exchange&lt;/p&gt;

&lt;i&gt;&amp;quot;He was proabably giving somewhere around 15V and I usually
give it somewhere between 16-18V.&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
As Erik says, parallel programming does require close adherence to
the specifications.&lt;/p&gt;

&lt;p&gt;
So, what is the specified power supply for this &amp;quot;programmer&amp;quot;? If
you are operating it out-of-spec, then all bets are off; there is no
reason to believe that it will operate correctly - you are in
&lt;b&gt;&lt;i&gt;undefined&lt;/i&gt; operation&lt;/b&gt; territory.&lt;/p&gt;

programming requires &lt;b&gt;absolute precision&lt;/b&gt; of everything.&lt;/p&gt;

&lt;p&gt;
I actually doubt your voltage is the problem, but my first action
would be trying to fix that.&lt;/p&gt;

&lt;p&gt;
If the &amp;#39;programmer&amp;#39; is connected to the serial port, read on,
otherwise tell us how it is connected to the PC:&lt;/p&gt;

&lt;p&gt;
My best guess is that the &amp;#39;programmer&amp;#39; is &amp;#39;cheating&amp;#39; on the RS232
interface which will make it work with some PCs and not with
others.&lt;/p&gt;

&lt;p&gt;
Did the &amp;#39;programmer&amp;#39; work before you changed your PC?&lt;/p&gt;

&lt;p&gt;
If you can, see if the &amp;quot;programmer&amp;quot; contains a
MAX232(equivalent)&lt;/p&gt;

&lt;p&gt;

I took my programmer to the persom form where I bought it. My
programmer was working perfectly at his place and writing the files
which gave me a verify failed error.&lt;/p&gt;

&lt;p&gt;
I used the same programmer, software and controller but was
working perfectly fine at his place. The only difference was that we
used different power supplies. He was proabably giving somewhere
around 15V and I usually give it somewhere between 16-18V. Now is it
possible that due to the different voltage levels my programmer burns
some codes and gives error on others?&lt;/p&gt;

Then Find out.&lt;/p&gt;

&lt;p&gt;
Try your program / chip on their programer and see if they
work.&lt;/p&gt;

My programmer uses intel-hex file, and I guess I will get a new
programmer.&lt;/p&gt;

&lt;p&gt;
Actually this particular programmer is used by many people and it
works fine, maybe mine is faulty.&lt;/p&gt;

&lt;p&gt;
Aynways thanx for your help.&lt;/p&gt;

A programmer built using a AT89C51 is not the same as a programmer
built to program a AT89C51.&lt;/p&gt;

&lt;p&gt;
Your programmer does not seem to correctly program your chip.
Isn&amp;#39;t that an indication that you should get a different
programmer?&lt;/p&gt;

&lt;p&gt;
Another thing: what file formats does it make use of? Binary?
Intel-Hex? Other format? Maybe it has buggy code to read the input
file.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Problem with Writing the code on Controller</title><link>https://community.arm.com/thread/124337?ContentTypeID=1</link><pubDate>Thu, 27 Dec 2007 08:41:43 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:be8ba9d2-7e35-43fa-840f-6426d5426d96</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
&lt;i&gt;The programmer I am using is definitly for AT89C51&lt;/i&gt;&lt;br /&gt;
that only means it it likely to be faulty. The Atmel programming is
so finicky that 99% of the kitchen table approaches that &amp;#39;work&amp;#39; has
problems.&lt;br /&gt;
This is not whether is is somebodys wet dream of how to program
Atmel, it is that if ANYTHING is 1% or less off the Atmel
expectations it will, most likely fail. As an example replacing a VHC
chip in somebodys illusion of an Atmel programmer with an
&lt;b&gt;equivalent&lt;/b&gt; HC chip makes the &amp;#39;working&amp;#39; design fail. Not to
mention that there are &amp;#39;;designs&amp;#39; on the web that are guaranteed not
to work unless your PC is brand x running Windows rev y. That, of
course, is NOT stated.&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;The only thing i am asking is wether its possible dat the
programmer has some fault and is not burning some codes?&lt;/i&gt;&lt;br /&gt;
not just &amp;#39;possible&amp;#39; but &lt;b&gt;likely&lt;/b&gt;&lt;/p&gt;

The programmer I am using is definitly for AT89C51, though it is
kindof handmade. The programmer uses a AT89C51 chip to program so
there is no chance dat its not compatible.&lt;/p&gt;

&lt;p&gt;

&lt;i&gt;I think my programmer is faulty ... is it possible?&lt;/i&gt;&lt;br /&gt;
no, I would say likely.&lt;/p&gt;

&lt;p&gt;
BUY the blasted Atmel programming interface (it is not THAT
expensive) instead of using your kitchen table concoction, I do
believe that the most frequent subject here and at 8052.com is &amp;quot;why
does my correctly made programmer not program an Atmel chip&amp;quot; which
ALWAYS end up &amp;quot;because it is not to spec&amp;quot;&lt;/p&gt;

So are you suggesting that the s/w ezdl4 is the problem?&lt;/p&gt;

AT89C51 ... using ezdl4 s/w..&lt;/p&gt;

&lt;p&gt;
why do you do that? AFAIK FLIP (provided for free hy the
manufacturer of you chip) works.&lt;/p&gt;

&lt;p&gt;
WHY, OH WHY do so many use kitchen table solutions when authorized
working solutions are available for free.&lt;/p&gt;
