LPCXpresso MAP file

When mapping variables to memory regions other then the default BSS, the map file seems to not attach the variable name.

Why is that?

E.g.:

static osStack_t digitaliotaskstack[128];

Will appear in the map file:

.bss.digitaliotaskstack
0x02002d64 0x200 ./app/digital_io.o

Where as mapped to RAM3 bank:

static __BSS(RAM3) osStack_t digitaliotaskstack[128];

it will appear in the map file as:

.bss.$RAM3 0x02005868 0x200 ./app/digital_io.o

That seem strange to me.

Thanks in advance,

Shlomi

The naming used is to allow the item to be placed into the correct memory block by the linker script. However the cr_section_macros.h header also provides macros "__BSS_EXT" and __DATA_EXT" which can be used to place DATA/BSS items into a more specifically named section than the default ".BSS.$RAM3" etc using something like:

__BSS_EXT(RAM3,digitaliotaskstack) osStack_t digitaliotaskstack[128];
