MC56F8357 - external RAM Test

[vineethcn]

Hello All,

     I'm working on external data RAM with the DSC MC56F8357. I am able to read and write external RAM.  I use CW 8.3 version and In linker command file (.cmd) i defined external memory address range and added section definition. In code i use Pragma, this every thing works fine for me. But now i need to add a test code to test the external RAM.

Kindly guide me how to develop the external RAM test code. All your comments and guidelines/notes are most welcome.

Thanks.

Hello Vineeth

There is no difference to test the external RAM with internal RAM or any other memory type (e.g. internal flash). 

The common method is verification by writing and reading back. Or you may use CRC check.  On this point, external memory is not special.
