I've read through that thread 4 or 5 times, I guess you mean I'm just too dumb then...
 

Hello together

I made some effort because I found a mistake in my layout. Pin 25 and Pin26 of the PIC18F4550 are wrong connected to PIC16F877
Now the self test brings me the following warning:

Connecting to MPLAB ICD 2
...Connected
Setting Vdd source to MPLAB ICD 2
ICDWarn0020: Invalid target device id (expected=0x21, read=0x0)
...Reading ICD Product ID
Running ICD Self Test
... Failed Self Test. See ICD2 Settings (status tab) for details.
MPLAB ICD 2 Ready

It seems that it could be OK

Thank you and best regards
Geri
 

azn_oohwee:

Your schematics has multiple mistakes and WILL NOT WORK!!!

Please correct them or remove your post as this will create problems for other people!!!

- Applying 5V to Vusb pin of 4550 will damage internal regulator.

This is ok, if you haven't connected target device, or the connection is bad between the target device and icd2.
Failed Self Test. See ICD2 Settings (status tab) for details.

Maybe one of the voltage divider resistors is too small or high, and icd2 thinks that there is a problem with the voltages.
 

Hello together

@potyo: Thank you very much for your help!!! I have checked inside ICD-Settings-Register STATUS: and all signals are indicated as passed.
Register POWER: Target Vdd 5V, Target Vpp 13V, MPLAB ICD 2 VPP 12V
Regiser VERSION: Debug Exec Version no information available

Programming works very fine

In debug mode I get the message
ICD0083: Target not in debug mode, unable to perform operation

Does anybody have an idea?

Best regards
Geri
 

Geri,

which design did you use?
 

@acrobat

a mixture but I would say it is more or less the one of Andy_123.

Best regards
Geri
 

That's my favourite too... just need time to redraw the schematics for my dil40 pics.

probable solutions to you problems.

Hello Polymath

Thank you for your help. I read the information ant tried more or less of the points but maybe it is a problem with the transistor.

in another thread I found this text:


I hope this is the problem
Best regards and thank you again

Hi, just to make it clear. Is it OK to connect ICD2 Clone that powered by +5V to the PIC24 & dsPIC33 that have lower operating voltage? If can, how to do it? Can I just separate both power supply (+5V for my ICD2 clone, +3.3V for my target device and of course with common ground)? Next thing, is it PGC & PGD on the target device (PIC24 & dsPIC33) can handle voltage signal more than +3.3V for example +4.7V with no harm to the target itself?

Hopefully somebody can explain more about this.

Best regards.

Please don't clutter this thread with another topic.

As you know there already a thread for this topic

and you have already posted the question there.

Try waiting for a reply or do research and figure it out for yourself and help others.

It's already quite cluttered, maybe it would be a good idea to collect all the information on a web page instead of 300 posts?
 

I setup a Wiki on my domain that we can use to compile all the information

what prograM can we use to open gebber files has they look like note book files

polymath,

Sorry..... there is so many topic in these forum...... I just found the correct channel...

TQ

You can use CAM 350. Use the autoimport function.
The CAM will auto-recognize all files to you.

Hi Everyone,

Thanks for the good work for making this clone possible.

Most of the design in this post are simplified version. Just wonder has anyone include the d-pot in this ICD2?

Regards.
 

I'm thinking on adding the d-pot along with the 4066 switches on my second board. I already have posted my preliminary schematic with the 4066, but the pcb is not built yet.
