Freescale has discovered a test inadequacy in the RAM for MPN MCF528x and MCF5214/6.  This could result in delivered product exhibiting RAM failures at a maximum failure rate estimated at 2-6%, based on fallout from test of similar devices. We do not expect the performance or reliability of affected units to degrade with time. This test code will allow for the identification of parts with defective internal SRAM and Cache.  Parts with data code before WW 10 and YR 05 are all affected.  Parts that have been screened and test by Freescale will have a 'T' on them.  

There are three folders included.  
The folder 'CW5.0 mcf5282 tests' contains a Metrowerks Codewarrior 5.0 project with five targets to test for defective parts.  The project file is located in ../build/mwerks/mcf5282.mcp

The folder 'CW4.0 mcf5282 tests' contains a Metrowerks Codewarrior 4.0 project with five targets to test for defective parts.  The project file is located in ../build/mwerks/mcf5282.mcp

If you don't have Codewarrior 4.0 or 5.0 the binaries, elfs, and .s19s are provided in the 'Object' directory.  With the elf files you should be able to download the code and run it with any debugger.  

In addition, all source code is provided to allow for the porting of the projects to any development tool.  The general file structure is below:

'CW5.0 mcf5282 tests' and 'CW4.0 mcf5282 tests' - Contain source files, build files for CW4.0 and 5.0.

..\build\mwerks - contains build files including linker files and .mcp project file

..\obj\mwerks\RAM tests - output directory for object files

..\src - contains all source files necessary to build targets

..\src\init - initialization files shared by all targets

..\src\Cache Test Lower - contains the source files used in the Cache Test target

..\src\RAM Test Lower - contains the source files used in the RAM Test Lower target

..\src\RAM Test Upper - contains the source files used in the RAM Test Upper target
