Need help / verification error and invalid target id warning PIC16F877

[HenrikOlsson]

Hi,
Have you selected the correct target device in the MPLAB IDE?


If you have then it sounds to me like a problem with the communications between the device and the ICD2. But I don't have any experience with the ICD2 debugger/programmer...

yes it is the right device.
If thats the case,then what are possibilities that can make that go wrong?What do i need to do?

Possible causes....
Faulty ICD2
Faulty or wrong cable between target board and ICD2
Problem with the powersupply on the target board
Target board contains circuitry that prevents the ICD2 from functioning:



Make sure you read and understand the section in the ICD2 manual that covers the hardware connections. There's also a complete chapter on troubleshooting which I suggest you read.

Apart from that I'm afraid I can't help much since I don't have an ICD2 myself. Since you have a supervisor perhaps you could consult him/her.

/Henrik.
