Strange issue came up from another project a friend is working on. Building and flashing within the C18 compiler, its just fine. Now if I take the .hex to another PC and try and flash it says its doing it, verifies...but the target does not run. To validate the setup, I can flash other targets built in assembly with that other PC and ICD3 by importing the hex file. It appears ONLY when built with the C18, it won't flash correctly. I am using MPLAB 8.3, ICD3 and current version of the C18 release. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
