Tried to use the memory map plugin on a STM32 ARM project, and I can not get any usable results. I seems to be working, but sizes in the graph is wrong. Always only 1 kbyte reported.
Looked around and found this issue. Maybe it is just a case of ARM not beeing supported yet.(?) There is however no info that I have seen that suggests that. Please have a look at the attached files.

Yes, ARM isn't supported yet...we hope to soon do it. Your files can help us as a good example. Thanks for that.
The compilers we support, are actually those available to chose in the plugin configuration.

It turns out that the GCC parser actually supports ARM32 when comping with a gcc-arm-none-eabi-* compiler. There are however a few problems needing workarounds and bugfixes.

• WordSize and radix when doing hex to dec conversion is mixed up, bug fixed in PR Fixed the wordsize/radix mixup bug.  #37 .
• INCLUDE file statements in linker command files are not supported. I did a workaround in Jenkins with a shell build step concatenating all need files into one linker command file. Needs fixing in this plugin, as it crashes when using such a set of linker files. It probably looks incomplete to the plugin.
• WordSize can be misunderstood. At first I thought that was the processor wordsize, e.g. STM32 is a 32-bit processor but still uses byte addressing and byte sizes. The Word size setting is NOT the processor wordsize, but rather the size used in the map file. i.e. must be set to 8 even on a 32-bit CPU. Might need some clarification. Help text says "The word size of the processor", this is wrong. It is "The word size in the map files."
