When i attempt to compile to chip using an ICD 3 programmer and Explorer 16 development board, I get s successful compilation and successful hex file generation and the file is programmed into the chip, but it doesn't work. I've also compiled to hex successfully, but when using MPLAB IPE, I get the same results....successful programming, but doesn't work. I've double-checked the configuration file to ensure it matches the board. I've also configured the compiler options to point to the correct location and parameters.

I've also checked the integrity of the chip and development board by loading a Microchip sample file into the chip. It works.

So, the question is, am I missing something or is it a bug?

FC7 v7.3.0.5
Windows 10 64-bit
MPLABX IDE v4.05
MPLAB IPE v4.05

Have you tried a simple blink a led program?

Yes. (see attached)

Hi
If you are using the Explorer 16 it seems the LEDS ae connected to PORTA and you have PORTD in your Flowchart
So I am confused
Are you using External leds connected to PORTD or are you trying to Switch the LED on the Board ON and OFF ?
it will help if you could give more detail about your setup

Indeed, you are correct!
That's what happens when I look at the PCB instead of the schematic.
Thee LED's are labeled D3-D10.
Doh!
Thank you for catching that!

Great Happy you got it
