PIC Kit Debug Error

[hock]

i am using pic-kit 2 with my own pic boards.everything use to work fine last year.
the boards are working fine if i program them in program mode.
when i try to debug i get the following error.
can some one please help me. i have used 3 versions of MPLAB.

sounds like your chip is not debug enabled, what chip are you using as you may need debug header.

plus has your pickit2 been fitted with the 4k7 pulldown resistors to help with debug mode.
look on microchip site for details on how to fit them.

i am using pic16f917 with official pickit2, red button. i think i do not need the resistor.
all used to work well till last year on the same board.

i do not use PIC very often..

Check HW oscillator or configuration (ICD debug mode, wdt, LVP program mode) - ICD interface work fine, but CPU can't run. Or power supply.

Take a look here http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en027813

Use AC162060 ICD header & AC164110 adapter.
PIC16F87, 88
PIC16F818, 819
PIC16F870, 871, 872, 873, 874, 876, 877
PIC16F873A, 874A, 876A, 877A
PIC16F882, 883, 884, 886, 887
PIC16F913, 914, 916, 917
PIC16F946

your quote makes it look like a debug header is needed for the 16F917, thats not true the parts that have a * need a headed for debug.

My bad. I was reading the list to quick. With my squinting eye . The 917 do not need a debug header. As many of the newer PIC variants. The debug logic is on chip

Like the project manager (Dave Hewett ex Thorn EMI) that said we could not use the 16F917 in a design for switch monitor as the 16F917 was for LCD displays "Its in the Data sheet".
