WARNING: DO NOT INSTALL MPLAB V8.33 - PMP is not yet compatible with the new "generic" format of linker scripts (what a new idea!!!).
Maybe this applies to V8.30 (not tested yet).
Sentence to think about : Slow and methodical testing like this will eventually get you to a point where you will either be able to spot the bug, or go quietly insane. Maybe both. Persistence of Vision 2.1 software documentation.
