I'm having some trouble with my ICD and a 16F877. Yesterday, before going home, all was great. Program, step through code, etc, etc. no problem. Today, I come in, plug things in, and the ICD reports programming successfully, but when I try to reset it, I get an "error performing requested operation" error. Nothing about my setup has changed, I've checked this several times. I've tried restarting MPLAB, rebooting the machine, and resetting power to the ICD... nothing. Has anyone else had this problem? And know what the cause/solution is? I found another reference to this while searching piclist.com, but no answer.... help! matt -- http://www.piclist.com hint: The PICList is archived three different ways.
