All firmware components are built using either RVDS running under either Windows or Unix/Linux:
For Windows, ARM RVDS can be used to rebuild the library.
Use a CodeWarrior project file to rebuild the library. The
RVDS make utility is not supported.
GNUmake is available for UNIX and Linux.
If you are using GNUmake to rebuild the Boot Monitor, set
your default directory to install_directory/Firmware/Boot_Monitormake from a command shell.
To rebuild the platform library component, set your default
directory to install_directory/Firmware/platformmake from a command shell.
After rebuilding the Boot Monitor, load it into NOR flash, see Loading Boot Monitor into NOR flash.
After rebuilding the platform library, you can link platform.a from
the target build subdirectories with your application (see Building an application with the platform
library).
You can specify the following build options after the make command:
BIG_ENDIAN=1/0,
defining image endianness (Default 0, little endian)
THUMB=1/0, defining image state
(Default 0, ARM)
DEBUG=1/0, defining optimization
level (Default 0, optimized code)
VFP=1/0, defines VFP support
(Default 0, no VFP support).
The Boot Monitor must be built as a simple image. Scatter loading is not supported.
The build options define the subdirectory in the Builds directory
that contains the compile and link output:
<Debug>_<State>_<Endianness>_Endian + further component specific options
For example, Release_ARM_Little_Endian or Debug_Thumb_Big_Endian.
The makefile creates a directory called Builds if
it is not already present. The Builds directory
contains subdirectories for the specified make options
(for example, Debug_ARM_Little_Endian). To
delete the objects and images for all targets and delete the Builds directory,
type make clean all.
