Hi Fabricio,
I use the BMD with CW too and as I recall Mark is correct in that there is nothing to change in configuration (config.h).
But you might want to change your linker a bit. For example the original linker file has this line:
ROM_C000 = READ_ONLY 0xC000 TO 0xF7FF;
The address 0xF7FF leaves some room for the serial monitor. If you need the space for one reason or another, you can change it to 0xFEFF. This frees up some FLASH, but still leaves the last 256 bytes for vectors and reserve registers for FLASH. If you plan to reload the serial monitor at a later time it might be better to create a separate target so you can leave the serial monitor linker as is and create a new linker file for the new target.
It's a minor thing, but it puzzled me for a bit since I need to make use of that space and it didn't work until I figured the linker reserved room for the serial monitor.
