   sorry, don't know what you mean by "map file".

   can you be more specific?

   ah, you mean like a linker script?

   the linker scripts for the Maple are here:
   https://github.com/leaflabs/libmaple/tree/master/support/ld/maple

   flash.ld is what's used for flash builds, and ram.ld is for ram.

   using those is hard-coded into the IDE build system. however, if you're comfortable with the command line tools, you could always just customize the Makefile. the relevant variable is MEMORY_TARGET, and the relevant section is here:

   https://github.com/leaflabs/libmaple/blob/master/Makefile#L52

   your other, less near-term alternative is patching that part of the IDE source. if you decide to go that route, let me know; it can be a little bit of a pain to build the IDE.

   sorry that this is fairly non-specific information; let me know if i can help you further.

   edit: "near-term" -> "less near-term", oops

   mbolivar - I think what x893 might be asking for is an "old fashioned" map file.
   It contains all the symbols in a program, and the offsets of every symbol.
   It was the 'fixup table' for a program loader.

   GDB uses something similar. I think it used to be that symbols weren't stripped be default, for a/s/gdb's benefit, so much of the information was in the symbols table.

   I am pretty sure it is easy to make something like that, but my google-brain isn't working at the moment (due to two bottles of Sheppy's Cider, very yum, hick! :-)

   hi,

   If you use the 'unix toolchain' as documented in the leaf documentation, you can simply add the linker flag to generate a map file.

   In the LDFLAGS section of the libmaple makefile, add '-Wl,-Map,build/maple.map' to generate a maple.map file in build/.
