MPASM

The required macros for this toolchain are:

  • MP_PROCESSOR_OPTION
  • MP_LINKER_DEBUG_OPTION

MP_LINKER_DEBUG_OPTION needs to be defined even if the definition is to nothing (MP_LINKER_DEBUG_OPTION=). This macro is only used when building a debug image. When the processor changes, this macro must also change to accommodate the places where the debug exec is stored, and how much data the debug exec uses. You can set this variable to nothing and the linker will build correctly, but any issues where code/data is placed on top of the debug exec will not be caught by the linker. So, it is best to set to the correct values. Correct values can be obtained by creating an MPLAB X IDE project with the correct device and doing a Debug Run, or by creating the Makefile using prjMakefilesGenerator.

The optional macros for this toolchain are:

  • MP_EXTRA_AS_PRE
  • MP_EXTRA_LD_PRE (for stand alone project)
  • MP_EXTRA_AR_PRE (for library project)
