PBP3.1 Gold + MCSX+ + Microchip's ICD3 programmer?

[Ioannis]

Most of the time, there is even no communication with the ICD3.

Something with Endpoint ..etc.

All start with the new MPLABX thing. When I used the MPLAB 8.xx it worked OK.

After changing firmware and swithced to X all went too bad.

It is too pity as I really liked it as it was before.

Oh, so your problem is with MPLABX. Welcome to the club.

It's not the ICD3 that's crap, it's MPLABX. I've had problems with all the tools in every version of MPLABX.
Some versions are better than others. I've had the least issues with the earlier V3.xx releases, but V4.xx is basically unusable for me.

I try and use MPLAB 8.92 whenever I can.

I get that too with icd3 and pk3 , I think it may be a usb issue unplugging and reconnecting programmer fixes it for a while.
saleae logic8 now does it too [keeps saying it can't keep up even @50k s/sec it used to do 16million] . perhaps my i5 laptop just does not keep pace with the real world any more now its bogged down in windoze 10

I have the issues at Win-7 64 with the ICD3 and sometimes with Pickit3 but none with Saleae so far. Taday I downloaded the Beta version but have not test it.

Unfortunately going back to MPLAB 8 is not always an option.

Also using third party hardware has issues too. For example my trusted old Elnec Pikprog+ does not support new devices anymore and I have to buy a new programmer...

I have had issues with this too with both pk3 and icd3 . today I noticed it was much worse when using salea logic no salea in use minimal connection losses , so I did a bit of googling . one suggestion was to use a powered usb hub.

well guess what it really works problem is gone

[Ioannis]

Then, what about using USB3 ports on the PC as they supply more current?

Ioannis

[richard]

its not a power issue, even if I power the hub through its usb connection only the pk3 icd3 still work.
neither is powering the dev board in use.
I wonder if the pc usb ports behave differently when a hub is detected ?

[Ioannis]

Strange...

Also I noticed that when the PK3 is changing/loading new firmware, if the controller to be programmed is not connected, the IPE stays in loading for ever. No timeout, ne message, just waiting.
