/* About M480_mem.h/M480_mem.icf.h
|
||||
*
|
||||
* 1. M480_mem.h is created for centralizing memory configuration. It will be included by C/C++ files
|
||||
* and linker files (except IAR linker file).
|
||||
* 2. IAR linker doesn't support preprocessor, so M480_mem.icf.h, duplicate of M480_mem.h
|
||||
* is created for IAR linker file.
|
||||
* 3. To continue above, we name M480_mem.icf.h instead of M480_mem.icf because:
|
||||
* (1) Mbed OS build tool may mis-regard M480_mem.icf as the main linker configuration file.
|
||||
* (2) *.icf files may not be present in search directories for "include" directive. Per observation,
|
||||
* the search directories are inconsistent among normal example build and test code build. To address
|
||||
* it, we name M480_mem.icf.h instead because *.h files are always present in these builds
|
||||
* (already there or via copy).
