Trying to follow these instructions verbatim: http://chipkit.net/programming-chipkit-boards-in-mplabx/

The problems seems to be that the new linker files don't, well, link. Without the linker files my project builds fine (the template project for the MX795F512L btw) and as soon as I add the linker files (appropriately modified as per link above) it can't find all kinds of references. Hrm.

Win 7 (64), MPLAB X v2.05, XC32 v1.31, PICkit 3 (not that it matters)

Thoughts? Thanks!

Are you using the right linker scripts? XC32 1.31 uses a new format that is different to the "old" version that "normal" MPIDE versions use.

You will have to use the linker scripts from the very latest test version of MPIDE (as that uses an open version of XC32 1.31): [url]http://chipkit.s3.amazonaws.com/index.html[/url]

Well, I downloaded the 20140316 build of MPIDE which looked to be the newest non-test release.

I'll try 0605-test.

20140605-test didn't build either.
