Hmm. I've been successful for some boards but sometimes when I try to connect the board, this is what I get...

Code:
*****************************************************

Connecting to MPLAB PICkit 3...

Currently loaded firmware on PICkit 3
Firmware Suite Version.....01.54.00
Firmware type..............dsPIC33E/24E
Target device was not found (could not detect target voltage VDD). You must connect to a target device to use PICkit 3.

You are trying to change protected boot memory. In order to do this you must select the "Boot, Secure and General Segments" option on the debug tool Secure Segment properties page.
Failed to program device
Too much current has been drawn on VDD. Please disconnect your circuit, check the CLK and DATA lines for shorts and then reconnect.

Any idea why this happens?

Also, I find that when I try to upload a custom bmminer, I get this same error all the time,

Code:
dsPIC33EP16GS202_get_pic_sw_version failed on Chain[1]!

Which I'll then have to flash your working HEX in order for that bmminer to work. Any idea why that happens as well? Thanks!
