> Might you have a quick linker tutorial somewhere? No, but my HAL project (http://www.embedinc.com/pic/hal.htm) comes with the necessary linker control file and complete build scripts so you can see how all the tools are run and what is passed to them. It is a complete buildable operational example. I don't think a linker tutorial is necessary. MPLINK is pretty much a run of the mill linker, actually dumber than most. When I first started with PICs I read all the MPASM/MPLIB/MPLINK docs and recall that the linker pretty much worked the way I expected it to and haven't given it much thought since. The only problem I remember was that the linker wanted the keywords in the control file to be upper case even though there was no mention of this in the manual (that I noticed, at least). Fortunately that didn't take long to figure out. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
