How to rebuild the EWL Libraries

The files (viz. libm.a, libc.a. ...etc.) are present in the ewl\lib folder under a sub-folder v<x>, where <x> is a number indicating the coldfire architecture. If the architecture supports PIC/PID then the library files for them will be present in a sub-folder (called pi) for that architecture.

The process to rebuild the EWL library files is given below.

1. Open a DOS command prompt.
2. Define the CWINSTALL environment variable ...

   For example, if the you CWINSTALL is in the folder C:\Freescale\CW MCU v10.x then you can define CWINSTALL as follows:

   set CWINSTALL='C:/Program Files/Freescale/CW MCU V10.x/MCU'

   Note: The single quote character (') is important because there are spaces in the path.
3. Change your working directory to the " ewl" folder, for example,

   cd C:\Freescale\CW MCU v10.x\MCU\ColdFire_Support\ewl

4. To clean the existing library files ... <path_to_make_utility>\make -f makefile clean

   You could skip the < path_to_make_utility> if you have " make" in your PATH variable.

5. All the library files can be re-built using the following command:

   make -s -f makefile PLATFORM=CF all cleanobj

   The "PLATFORM=CF" indicates that EWL is being re-built for ColdFire.

6. After the make command is complete, check the lib folder and its sub-folders for the presence of libm.a, libc.a, ...etc.

The EWL library files are rebuilt.
