Hi, I am trying to program a PIC32 with MPLAB X and a PICKit 3. My OS is Windows 7 64-bit. I installed the driver (I tested both windows default and Microchip driver), I installed Java in last 32 and 64 bits versions and tested them both. I'm running everything as administrator. When MPLAB tries to connect to the PICKit 3 after build and load, it returns this message :

BUILD SUCCESSFUL (total time: 554ms)
Loading E:/Kev/Documents/EPL/ELEC21/ELEC2531-ElectroniqueII/Travail6/MyApp_v1/MyApp_v1/dist/default/production/MyApp_v1.production.elf...
Configuration Bits: address 0x1FC02FF0: USERID = 65535 does not match any valid value in the device database. Setting it to the default value.
Loading completed
Connecting to programmer...
The programmer could not be started: Could not connect to tool hardware: PICkit3PlatformTool, com.microchip.mplab.mdbcore.PICKit3Tool.PICkit3DbgToolManager

My PICKit is plugged and detected by both Windows and MPLAB X (in the project properties). I'm not the only one who has this issue (with a similar configuration). I've tried everything I could... Can anyone help me ?

The error you are seing doesn't necessarily have to do with USB communications (although it might) so let's start with the basics. Please let me know what version of MPLABX you are using and what device you are trying to debug?

Thanks for your answer. I'm trying to program a custom PIC32 device (designed by my teacher) which, btw, is working fine with other computers. The exact reference is PIC32MX795F512H. I'm using the last version of MPLAX X (i.e. Beta 7.12).
I see the PICKit3 in the project properties when it is connected but MPLAB does not seem to connect.
I thought of a software conflict... is it possible ? If so do you have any idea of how can I troubleshoot and fix it ?

I just noticed that in the bottom right corner of MPLAB, we can click to see Java Exception. It says that:

java.lang.NullPointerException

Maybe it will help ?

I finally found an alternative solution! I don't know why but in windows safe mode, MPLABX is able to connect my PICKit3. So...
1) its not a driver issue
2) its not an installation issue
3) its not a java issue...

Furthermore, in normal mode, I can use the software PICKit3 Programmer V1.0.0.0. It detects and connects my PICKit3 and succeed to program my PIC32. All I have to do is to export the Built project from MPLABX into a hex file, import the hex file with PICKit3 Programmer and program it. I'm not fully happy with this pseudo-solution but well... it works. If I find out why MPLAB does not want to connect the PICKit in normal mode I'll tell you. Maybe the bug will be fixed in a next release.

One thing that caught my attention was the fact that you are also using the PICkit stand alone program as well.  You can't have more than one application connected to the PICkit at the same time. Make sure that the stand alone program is closed when you try to connect to MPLAB X.

dear friend. I'm experiencing the same problems. I can not connect with my PICkit3 using the MPLAB X. Using MPLAB 8 all stufs works perfectly. I think it's a bug in MPLAB X V1.0. Let's wait for a new version!

I had the same issue, and it turned out to be because I had MBLAB 8 open at the same time.  The PICkit3 was connecting to MPLAB 8 instead of MPLAB X v1.0.  So I just closed MPLAB 8, and now it works fine.

I FOUND THE SOLUTION. I got a hint from the above reply saying that it worked in Safemode, but not in normal mode.
I had the same issue in both MPLAB(v8.85) and MPLAB-X(v1.10) in Windows7 64bit. Both couldn't connect Pickit3.
 
Solution:
When you execute either MPLAB or MPLABX, you can run the program as an administrator. Then, it works beautifully~! For those who don't know how to run it as an administrator, you can right-click on the icon, then go to "properties", go to "Compatibility" tab, make sure "Run this program as an administrator" box is checked. Enjoy~!!

I can confirm that MPLABX does not see the Pickit3 when I run it as a normal user.
If I run the MPLABX as administrator, Pickit3 works properly.
I do NOT think this is a bug in MPLABX since I am experiencing the same issue with some other applications and other USB interfaces (such as logic analyser and its GUI app).
Using Windows7 64bit.
 
I have no clue where the problem is, I would guess somewhere in Windows USB permissions.
Possilble problematic apps: MS Virtual PC (USB sharing), NOD32 antivirus
Guys, do we have anything in common?

When you go to Properties of your project Which Hardware Tool you had selected? Instead of selecting PIC Kit 3 Serial Number Select PIC Kit 3 Main Tree Only. I was getting same error and it is solved once I have selected this way.

Let me report my case.  I apologize my poor English.

OS: Windows7 64bit
Solution: Update PICKit3's firmware with MPLAB v8.

This was first time I make PIC-program.
My Target IC is PIC24FJ64GB002 on "RT-ADK mini" .
I installed MPLABX v1.30 and C30. (the sample-program I wanted to
compile needed C30)
I tried also "Run In Administrator" but I didn't succeed  to write .hex to PIC.

So I tried MPLAB v8.86 and connected PICKit3.
I did that in menu ...
* Configure -> Select Device  "PIC24FJ64GB002"
* Programmer -> Select Programmer  "PICKit3"
 
Then MPLAB v8 updated PICKit3's firmware to below.

Firmware Suite Version...... 01.27.20
Firmware type......................dsPIC33F/24F/24H


I succeeded to write .hex to PIC. :-)


Next, I stopped MPLAB v8.86 and started MPLAB X v1.30 .
I succeeded to write with tool button.


I hope this information helps someone.
Thank you.

A way to work fine when change from Pickit3 standalone to MPLAB, is that you have to change opertation mode, but how ? easy ... Tools> Revert MPLAB mode. You'll have to do the same to use with Pickit3 standalone again !

Re:PICKit 3 Connection Failed MPLAB X Could not connect to tool hardware 2012/09/27 23:26:41
Hi,
 
My Pickit3 worked only in safe mode. Therefor I investigated which driver was the problem.
The following program caused the problem:
Name: LaunchHPOSIAPP
Path:  c:\program files (x86)\hewlett-packard\hp mainstream keyboard\launchapp.exe
I used the freeware program Autoruns  (see http://technet.microsoft.com/en-us/sysinternals) to disable this program in the tab Logon.
 
You can use autoruns to disable the drivers at logon and try which one cause the incompatibility.
 
Hope this helps you.
Succes!

Installed MPLAB X (Windows XP SP3) and PICkit 3 no longer works -- it shows up with the serial number, so I selected that for the project, but trying to RUN gets Connection Failed.
 

Product Version: MPLAB X IDE v1.41
Java: 1.6.0_32; Java HotSpot(TM) Client VM 20.7-b02
System: Windows XP version 5.1 running on x86; Cp1252; en_US (mplab)
Userdir: C:\Documents and Settings\Jay\Application Data\.mplab_ide\dev\v1.41

 
A very simple project builds successfully, but trying Debug Project gives:
BUILD SUCCESSFUL
Loading completed
Connecting to programmer...
The programmer could not be started: Could not connect to tool hardware: PICkit3PlatformTool, com.microchip.mplab.mdbcore.PICKit3Tool.PICkit3DbgToolManager
   and on the PICkit3 tab:
Connection Failed.
From the looks of it, this problem has been around since the beginning of time (for MPLAB X).  Is there seriously STILL no fix?  I can see this problem posted for literally years.  And I have the latest MPLAB X announced this month!
 
Can anyone help?

JPAX absolutely right on this... isn't acceptable to wait over a year for a fix, I have should of read this before take Microchips advise and buy Pickit3 instead of Pickt2, due to unfortunate circumstances my PICkit2 no longer works [8D] so I ordered Pickit3, what a waste of money......

Hi,

According to one of the stickied threads at the top of this forum section, the hardware tools sometimes have problems with USB 3.0 ports (and manufacturer's drivers).  I had the same connection problem with the PICkit 3 on my machine and was able to fix it by using a USB 2.x port.

I had the exact same problem (MPLAB X says "Connection Failed" when trying to program, but it works fine if you boot Windows (7, 64-bit) into safe mode).  In my case, the offending application was Fierce3500Config.exe, which is started at boot up and shows in the tray-icon area.  It is for programming the Fierce 3500 Wireless Gaming mouse, and I guess makes the extra non-standard buttons work.
I believe I've read three other accounts of people with similar problems, and it seems that in each case the problem had to do with a piece of software that had something to do with a human-interface device (HID).  Since the PICkit 3 uses the standard Windows HID drivers, I think the process of elimination in the search for the offending application may be shortened if you first eliminate all non-windows processes that are associated with any non-generic peripherals.
This has been an incredible waste of time for me (2 days), and so I hope this information helps somebody else shorten the time!

I had exactly the problem with my new MPLAB-X installation on a pretty new Dell computer. I installed MPLABX then plugged in a new Pickit3. I got the same error message:
Connecting to programmer...
"The programmer could not be started: Could not connect to tool hardware: PICkit3PlatformTool, com.microchip.mplab.mdbcore.PICkit3Tool.PICkit3DbgToolManager"
 
Thank you for the advice in the post above - it limited my delay for this problem to only 3-4 hours!
For others with the same problem - I went to the Task manager and ended the following processes:
accuweather.exe, Delldock.exe, IAStarIcon.exe, iTuneshelper.exe, RoxioBurnLauncher.exe, SynTPEnh.exe - Synaptics TouchPad Enhancements, SynTPHelper.exe, tbbMeter.exe, WebcamDell2.exe
Then I unplugged and replugged the Pickit3. When I tried to program a chip, the Pickit3 was recognized and the firmware updated and everything worked fine.
I rebooted the computer hoping that the update of the firmware might avoid any conflicts, but it didn't solve the problem.
In the end, I worked through each process in the Task manager, stopping it, unplugging and replugging the Pickit3 until finally I got MPLABX to recognise the pickit3.
It turned out to be the accuweather.exe process that caused the conflict.
So now I have to reboot, start MplabX, stop "accuweather.exe", plug in the pickit3 and it works!
It's really disappointing that Microchip haven't sorted this out yet! But thanks to the posters above and I hope this help further.

Just curious with the accuweather solution, is the PICkit 3 on USB 3.0 or USB 2.0 port? I have a similar problem but only on USB 3.0 but I don't have accuweather.

Re:PICKit 3 Connection Failed MPLAB X Could not connect to tool hardware 2013/02/24 13:56:23

I can confirm similar results to the two guest posts above. There appears to be a USB device or driver conflict that prevents MPLAB X from communicating with the PICkit 3. In my case it was with my generic USB keyboard. I now have everything working but have no way to confirm which of the steps I took are actually necessary.

The following is primarily for Microchip, I hope someone reads it, I wish to share my pain.
I bought a new PICkit 3 last week for use with MPLAB X. There was obviously a problem from the start as the status LED was always red. Tried to use the PICkit 3 in MPLAB X 1.51 and 1.6, and the IPE with the same "Connection Failed" error.
  • Tried switching ports as suggested above, status red, "Connection Failed".
  • Tried safe mode as suggested above, status red,  "Connection Failed".
  •  Reverted to MPLAB 8 where I had used a different PICkit 3 in the past and the new one was not detected.
  • Updated MPLAB 8 to 8.88 and the PICkit 3 was recognized, firmware loaded, but still did not program the PIC24 but the status led was no longer red.
  • Tried another design with a 16F887 that I've loaded hundreds of times, PICkit 3 firmware updated and device programmed successfully. Finally some progress.
  • Changed to PIC24, firmware updated and device programmed successfully. Real progress now.
  • Tried IPE with PIC24, firmware updated again, apparently requires different code than MPLAB 8, device programmed successfully.
  • Switched to MPLAB X, attempted to program PIC24, "Connection Failed".
  • Start disabling all usb devices until just mouse and keyboard are left. Disable keyboard, device programs successfully.

At this point, I do not think this is progress. I am feeling frustrated, dismayed, and outraged. To borrow a line, in what possible universe is it acceptable that my programmer/debugger only functions when my keyboard is disabled?! I resist the urge to introduce my 12 pound sledge hammer to the PICkit 3 and create some fine dust, for while that would be a very satisfying resolution, it would not be a satisfactory solution as I have work to do.

So I resume debugging my debugger. I have seen a PICkit 3 working with MPLAB X under normal conditions so I know it's possible. Many on this forum have posted that they have managed to get things working through a variety of trial and error methods.
  • I confirm I can only program with the PICkit 3 under MPLAB X with the keyboard disabled or unplugged.
  • Reboot with PICkit 3 plugged in, keyboard unplugged.
  • Program under MPLAB X no problem.
  • Plug in keyboard. It is NOT recognized!
  • Plug keyboard into a different port. Driver loaded, keyboard works, and I can program under MPLAB X.
  • Switch keyboard to usual port, everything still works.
  • Reboot. Everything still works.

So what happened there? I know nothing about usb driver and device registration under Windows 7 but some steps in that sequence clearly resolved the problem.

A final comment for Microchip. Please add a sticky post to this forum acknowledging that users may encounter usb problems with their PICkit 3, other than the usb 3.0 one already noted. At the very least include links to threads where people have found solutions so others do not waste hours or days trying to track down solutions to problems with a device that should work right out of the box.

Have you made sure:
 
1) You have the correct configuration settings?
 
2) You have the correct configuration settings selected?  
 
3) You have the correct PIC chip selected in your configuration settings?
 
4) Your PICkit 3 is selected to power the device?
 
Have you just encountered this problem or has it been going on for a long time?
 
Thanks.

Re:PICKit 3 Connection Failed MPLAB X Could not connect to tool hardware 2013/06/29 15:57:57
The issue of using the PICkit3 programmer device with MPLAB comes down to the Programming Mode configured in the PICkit programmer device.

PICkit 3 can run in two modes: MPLAB mode and another mode used by the PICkit Software Utility (PICkit programmer Application)

When the PICkit 3 is used for the first time with the Software Utility, the device downloads an OS compatible with the programmer, then changes its operating mode from MPLAB mode to the utility software's compatible mode.

To use PICkit 3 with MPLAB IDE, the operating mode of the device has to be set to MPLAB mode.

To go back and forth between those two modes, you need to install the Software Utility ( PICkit programmer Application). This can be obtained at http://ww1.microchip.com/downloads/en/DeviceDoc/PICkit3%200.2.0.3%20Setup.zip

Once you have the software utility installed, to set the MPLAB Mode:
 - Launch the software utility
 - Go to the "Tools" Menu
 - Click on the "Revert to MPLAB Mode" option

This will set the bootloader to run in a mode compatible with MPLAB IDE.

Similarly, to go back to the Software Utility mode:
 - Launch the Software Utility (if not launched yet)
 - Go to the "Tools" menu
 - Click on the "Download PICkit operating system" option


Try this and let me know if you're still having the same issue

I have started having this problem, Using MPLAB V1.95 with pickit 3, before windows 8 did the update to 8.1 it all worked fine, but now I get the connection failed error.
The build window says the programmer could not be started: could not connect to tool hardware: PICkit3PlatformTool, com.microchip.mplab.mdbcor.PICKit3Tool.PICkit3DbgToolManager
It isn't the pickit unit as I use the old mplad IDE for programming some older device and it works fine. I had used a work around, using my own program to program the Pickit3 using PK3CMD but now I can't get that to work as I am trying to use a newish pic chip 24EP256GP202 and it isn't listed under the old programming utilities.
 
I can not believe in nearly two years that a solution for this isn't available.
I have tried all the methods in previous posts without any luck. I tried the about option using the pickit3 software utility, but it didn't have the option to switch mode and the download operating system was grey out.
 
This is driving me mad as I have a deadline to work to,

Hi Paul-
You are suffering a USB driver problem. It probably got stepped on in the update...
If you are going thru a hub, go direct to the PC USB port.
If you have programs that play with the USB ports (like VirtualBox) try not starting them or killing them with ProcessExplorer (google it if you do not have it already).
If this fails bring up device manager and check the drivers and ports to see if the device is even recognized. You should be able to re-install the driver to get this working.
