Pickit2 Kaput?

Hi all,

Today I started having trouble with my PK2. Neither MPLAB nor PK2 programmer see it. Tried plugging it in whilst holding down the red button - red led flashes but it makes no difference. Tried it all my usb ports to no avail.

When I unplug it, XP keeps flashing up a 'usb device not recognised' message on the sys tray. That stops when I plug pickit2 back in though.

Is it destined for the bin or is there a fix?

Despondantly yours........


Thanks in advance for any help.

I recently had the red flashing light syndrome, think there was a crossed up wire on the breadboard icsp that put it in this state. The PK2 told me I needed to download the OS again, did so, and back in business again. Don't know what you would do if Windows doesn't even establish the USB connection.

Hi,

I managed to get it working although not sure how long it will remain reliable. Just kept plugging / unplugging it and then Pickit2 programmer made connection but said there was no operating system. Started to download operating system but it hung. Disconnected / reconnected and voila! Not sure it even actually downloaded the operating system. Oh well. Now I can at least plug it into the pcb I made yesterday, the first one I've done with mainly smd components. Unfortunately that doesn't seem to be working properley either! It's just one thing after another. Think I should take up knitting instead.

Thanks for the help anyway.

When you have programmer problems test the programmer using a know good target board. Once you have verified that the programmer works try it with the new/suspect target. Most of the time you will find that the target is the problem.
