It's clear now, it a device programmer OR device programmer software problem. Here's the dump of the PIC when i reload it

as you see, it far different from yours...

Yours can't work, let's see the first lines... wich are supposed to be the program stuff

those are good so far. If i program my PIC here with the dump you sent... i have nothing working... same thing as you get on your side.

So use another device programmer AND/or another software to fix the problem.

Woohoo we got it

Did your tried the capacitor stuff?

[malc-c]

Sorry Steve, you lost me there !

Are you saying that its a hardware issue (the Olimex PG-02 programmer) or software (winpic or picpgm) - or a incompatibility between either and the 18F2550. It has worked fine in the past with other PICs ??

I've just tried an option on the WinPIC software, and programmed the CODE only. The code loaded with no issues as can be seen by the log below

Programming...
Erasing: CODE ..

Programming finished, no errors.

I then unchecked the data and code boxes and just tried the config memory box - The first time I tried it it errored - the second time it worked

Rechecking all the boxed I varified the PIC and it reported

I've attached the config memory settings displayed under that tab - I have no idea if they are right ?

I also need to re-build the breadboard as I've used it for something else i was playing with, so I can't confirm yet if doing it this way has worked and your test code is actually working when hooked up as per the schematic I posted eariler.

Could be both, i just compared the dumped.txt file with the .HEX i got here when reading back the PIC. As you see, yours is blank on the firsts lines (0000) wich is the program area.

Couldn't find "C:\Program Files\Microchip\MPLAB IDE\PIC18F2550.dev", please borrow/copy from MPLAB !

i found it here in the same path... just make sure you have this file as well OR re-install MPLAB 7.50.

it have something to do as it state the programming area range, config fuse mem addresses etc etc.

mmm

[malc-c]

I've breadborded it and it still does not work...

[mister_e]

how about the PIC18F2550.dev File?

[mister_e]

Looking at their schematic...
<img src="http://www.olimex.com/dev/images/pic-pg2c-sch.gif">

PGM pin is left floating (sv3-3)... but you said you already tied it to gnd so it shouldn't be the problem... should

You said MCLR/VPP was close to 13Volts... so couldn't be this

So if the Software is not well done, this poor device programmer can't work properly. 18Fs are a little bit more tricky and noise sensitive..

Can you just try to use ICSP?

Something like ... (courtesy of Melabs)

Verify Error: 300000: read 000000, wanted 0030C0, mask 00FFFF ==> diff=0030C0

Verify Error: 300006: read 0000A1, wanted 00FFBB, mask 00FFFF ==> diff=00FF1A

So now it doesn't program the config fuses.... not even better. Read back the PIC and post the first lines of the .HEX files.

I don't know if it could be a XP issue or not, but if the timing is not good when programming, for sure it will never work as expected.

Steve,

Just tried using ICSP and that failed too

Steve,

I've pointed the programmer to the correct path of the DEV files and it made no difference. ( as you can see no message saying it can't find the file)

I also typed in the "30C0 and CEFE" into the first two config memory locations and tryed programming that - it errored as before.

I've had this programmer working as I've used it to program USB RC-Joystick file, but I've juts tried that code and it too errored. The only difference is I'm now using XP Home and SP2, but I'm sure that would have no bearing on this issue ?

EDIT - oh and this was the third and last 18F2550 PIC I had 0 fresh out of the tube !
