Matrix user forums

Hi everyone,

I want to program a chip with a PICKit 4 like this PICKit 3 exemple.

But IPECMD don't want to apply /W parameter and display this error :

The configuration is set for the target board to supply its own power but no voltage has been detected on VDD. Please ensure you have your target powered up and try again.
Connection Failed.

This is my command line (BUR181413665 is my PICKit 4 serial number) :

C:\Program Files (x86)\Microchip\MPLABX\v4.15\mplab_ipe\ipecmd.exe /P12F683 /F"C:\test\Flowcode1.hex" -TSBUR181413665 /M /OL /W5

I tryed without success : /W /W5 -W5 /W5.0 /W5.00 /W5.000 /W5.0000 /W"5"

Please note that I have no problem with the IPE GUI.

Do you have a solution for me ?

Thank you.

Matrix staff, do you have a privileged relation with Microchip to report this bug ?

Have you tried the Microchip forums? Or even logging a support call with Microchip?

I have tried to post a new thread to the Microchip forums but my post never been accepted.
I have tried to sent an e-mail to PICkit4_update@microchip.com but I haven't received response.

I hope version 4.20 will fix this bug.

Hello,

We can certainly ask the question for you but it will likely end up on the standard support email as we generally deal with the marketing/sales side of the company. I have a PICkit 4 here but haven't yet been able to put it through its paces. Hopefully I can find some time soon to have a play and document what is required.

The microchip forums can take a while to refresh, probably due to anti spam reasons.

Hello,

Looking on the Microchip forums it appears we have to wait for MPLABX 4.20 to be released. It was pencilled in for April so hopefully it's coming soon.

MPLABX v4.20 solved the problem.

New location : C:\Program Files (x86)\Microchip\MPLABX\v4.20\mplab_platform\mplab_ipe\ipecmd.exe
New PICKit 4 parameter : /TPPK4

Powered externally
Location : C:\Program Files (x86)\Microchip\MPLABX\v4.20\mplab_platform\mplab_ipe\ipecmd.exe

Powered via the PICKit
Location : C:\Program Files (x86)\Microchip\MPLABX\v4.20\mplab_platform\mplab_ipe\ipecmd.exe
Parameters - Powered at 3V3 : /P$(chip) /F"$(outdir)$(target).hex" /TPPK4 /M /OL /W3.3

That's brilliant thanks for posting and for providing the details.

I have now added this information to the 3rd party programming tools section of the wiki.
