EtherDongle programming

[Segull]

checked voltage regulators and touched up solder. Checked all resistors, all match. Touched up all solder points 

trying to check traces as MrChristmas suggested.

Thank you again.... the mystery continues

You don't want to buy a lottery ticket right now because I think your luck is not at a very high level right now. 

Continuity checking a high density chip is a real challenge. I hope that you find what the problem is.

[MrChristmas2000]

I pulled out one of my e-dongles to reprogram it with DMX for a test.

Now I remember that you definitely have to have the dongles power supply plugged in to make it program.

When you attempt to read the device without the power hooked up you will get 'device not found'.

Once I connected power to the dongle, restarted the PICkit 3 program, set the device type to 'PIC32MX795F512L' which is the device all the way at the bottom of the list I could read, erase, and reprogram the device. The check sum stayed at 000. Be sure the PICkit 3 is pointed (inport file) to the correct code file.

[Segull]

ok, I double checked my settings using Pickit 3 Programmer ver 1.0 from the Wiki, but got error:  "operation failed" I tried Erase, Read, same message.
And yes check sum stayed at 000.

Thank again, back to my search

just sent a PM

I will come by and see if we can get it going.

That is beginning to look like either a bad pickit.  The only other thing that I would suggest if possible is to try the device on another PC.  There could be something in either the PC or the OS that is interfering with communication between the Picket and the software.

If it comes down to being a soldering issue on the pic let me know. We will need to get it fixed.

RJ

Since he appears to be getting the same failure on other devices, it looks like the EDT board is ok.

[keitha43]

No he said it read his LE chip just fine.

[Segull]

Thank you RJ,
Glen has kindly offered, so I am anxious to meet a DLA friend as well as see what I have missed on my soldering 

Thank you RJ, tbone and keith

This may not help Segull, but in case others are having trouble and reading this -- I second the previous comment about device interference.  In particular, check any and all USB devices and drivers you have installed on the system.  I saw a report of at least one case where this was causing problems with PICKit 3 communication.

Update,
I was able to get with a fellow DLA, Glen, tested with his Pic3 and got the same results.
I used my Pic3 on his EtherDongle and was able to program with no issues.

Glen looked over the EtherDongle very carefully but found all looked OK.

So I know that my Pic3 works, but EtherDongle still does not program.
When I use the programmer I get "operation failed".
And when I use MPLAB IDE I get "PK3Err0035:Failed to get Device ID".

Anyone have any ideas?

[MrChristmas2000]

Didn't RJ volunteer to get it fixed? I'd take him up on that offer.

[Segull]

I wanted to bring this issue to its conclusion. I took up RJ's offer to check the EtherDongle and this is what he found. "There was a super small bit of solder between two pins on the pic."

Thank you to all who made suggestions on things to try. To Glen, a fellow DLA member that I got to meet for the first time, and especially RJ, for taking some time to trouble shoot my issue 

Thank you all
Joe
